How to Choose a Scale for Epoxy Pigments

Posted by AWS Team on Sep 2nd 2026

Choosing a scale for epoxy pigments starts with one simple question:

What is the smallest amount of pigment you actually need to measure?

Pigments, mica powders, metallic powders, dyes and other resin colorants are often used in much smaller quantities than the resin itself. Because of that, the best scale for pigments may be very different from the scale you use for resin and hardener.

For many epoxy pigment applications, a practical starting range is:

100–500g capacity × 0.01g readability

This combination can provide enough capacity for a small weighing container, pigment and even a small resin sample while displaying changes in hundredths of a gram.

But 0.01g is not automatically the correct choice for everyone.

Some makers can work comfortably with 0.1g readability, while applications involving genuinely milligram-level quantities may require 0.001g.

The right choice depends on:

Your smallest pigment quantity
Your largest complete load
Readability
Accuracy specifications
Minimum usable load
Repeatability
Tare
Calibration
Platform size
Your weighing environment

This guide explains how to choose a scale for epoxy pigments without paying for precision you do not need—or choosing a scale that is too coarse for your formulations.

Quick Answer: What Scale Should You Choose for Epoxy Pigments?

Use this as a starting point:

Pigment Application	Suggested Capacity	Suggested Readability
General mica powder	100–500g	0.01–0.1g
Small pigment formulas	100–500g	0.01g
Concentrated colorants	100–500g	0.01g
Metallic powders	100–500g	0.01g
Glitter and larger additives	200–500g	0.01–0.1g
Resin jewelry pigments	100–500g	0.01g
Small color-development batches	100–500g	0.01g
Milligram-level ingredients	Appropriate low capacity	0.001g when genuinely required

For many hobbyists and resin artists:

500g × 0.01g

is an especially versatile specification.

It offers substantially more capacity than an ultra-low-capacity milligram scale while still displaying measurements to the hundredth of a gram.

American Weigh Scales explains the relationship between these specifications in What Does 500g × 0.01g Mean on a Digital Scale?.

1. Start With the Smallest Pigment Quantity You Use

Do not start by shopping for the scale with the most decimal places.

Start with your formulation.

Ask:

What is the smallest amount I regularly need to measure?

Suppose your normal pigment quantities are:

5g
8g
12g

You may not need 0.01g readability.

But suppose your formulas look more like:

0.25g
0.45g
0.75g
1.20g

Now hundredth-of-a-gram readability becomes much more useful.

And if your actual formulation requires:

0.015g

then you may need to investigate milligram-level equipment.

The scale should match the measurement—not the other way around.

2. Understand What Readability Means

Readability is the smallest increment shown by the scale's display.

Common options include:

0.1g

0.01g

0.001g

These specifications represent very different measurement ranges.

A 0.1g scale might display:

2.3g

A 0.01g scale might display:

2.34g

A 0.001g scale might display:

2.347g

More digits provide finer displayed increments, but they do not automatically make a scale more accurate or better suited to epoxy pigment work.

3. When Is 0.1g Enough for Epoxy Pigments?

A 0.1g scale displays tenths of a gram.

Examples:

2.1g
2.2g
2.3g

This may be sufficient when:

Pigment quantities are several grams or more
You use larger amounts of glitter
You work with larger resin batches
Hundredth-of-a-gram differences are not important to the formulation
The scale is also used for resin and hardener

A 0.1g scale can also provide substantially more capacity than many fine precision scales.

For general resin work, AWS notes that 0.1g provides a practical balance between capacity and displayed detail. Read How to Choose a Scale for Resin.

For pigment-specific work, however, 0.01g can often be more useful.

4. When Should You Choose 0.01g?

A 0.01g scale displays hundredths of a gram.

For example:

0.25g
0.48g
0.72g
1.36g

This is useful when:

Pigments regularly weigh less than 1g
You make small resin batches
You formulate resin jewelry colors
You combine several pigments
You use concentrated colorants
You perform pigment tests
You want to document repeatable formulas

For many resin pigment applications, 0.01g is the practical sweet spot.

It provides much more displayed detail than 0.1g without automatically moving you into the more environmentally sensitive world of milligram measurement.

5. When Should You Choose 0.001g?

A 0.001g scale displays thousandths of a gram.

That is:

one milligram

This level of readability is useful when the actual ingredient quantity genuinely requires milligram-level measurement.

For example:

0.015g

cannot be meaningfully displayed on a 0.01g scale with the same level of detail.

But 0.001g scales involve tradeoffs.

They tend to be more sensitive to:

Drafts
Vibration
Static
Temperature changes
Surface movement
Off-center loading
Movement around the workbench

For most normal epoxy pigment applications, 0.01g is more practical than 0.001g.

AWS explains the difference in greater depth in 0.001g vs. 0.01g Scales: Which Precision Do You Need?.

6. Do Not Confuse Readability With Accuracy

This is one of the biggest mistakes when choosing a scale for epoxy pigments.

Suppose a scale displays:

1.27g

That tells you the scale has 0.01g readability.

It does not automatically establish that the measurement is guaranteed accurate to exactly ±0.01g.

These terms describe different characteristics.

Readability

The smallest increment displayed.

Accuracy

How closely a measurement agrees with an appropriate reference under specified conditions.

Repeatability

How consistently the scale produces the same measurement when the same stable load is measured repeatedly under similar conditions.

Minimum Load

The lower part of the weighing range at which useful measurement performance can be expected according to the scale's specifications.

When comparing scales, evaluate all of these rather than simply choosing the model with the longest decimal display.

For broader technical context, the National Institute of Standards and Technology's Mass Standards program explains how reference mass and measurement uncertainty form the foundation of dependable mass calibration.

7. Minimum Usable Load Is Especially Important for Pigments

A scale marked:

500g × 0.01g

has:

500g maximum capacity

and:

0.01g readability

It does not automatically mean that 0.01g is the ideal minimum working quantity.

The smallest displayed increment and the smallest dependable working load are not necessarily identical.

If your pigment formula requires extremely small quantities, investigate the manufacturer's:

Minimum load
Accuracy specification
Repeatability
Tolerance

This becomes increasingly important as your measurements approach the lower end of the scale's range.

8. Choose Capacity After Calculating the Complete Load

Pigments may weigh less than one gram.

That does not necessarily mean a 50g or 100g scale is enough.

Remember what actually sits on the platform.

Your complete load may include:

Container + resin sample + pigment + additives

For example:

Container = 45g

Resin sample = 125g

Pigment = 2g

Additional colorant = 1g

Total physical load:

45 + 125 + 2 + 1 = 173g

A 100g scale would not be sufficient.

A 500g scale provides much more flexibility.

9. Why 500g × 0.01g Is So Useful

For many resin artists, 500g × 0.01g provides an excellent balance.

You get enough capacity for:

Pigment cups
Small resin containers
Jewelry batches
Formula-development samples
Multiple colorants
Lightweight additives

while maintaining hundredth-of-a-gram readability.

This makes a 500g × 0.01g scale more versatile than an extremely low-capacity precision scale for many normal resin workshops.

10. Remember That the Container Counts

Suppose your pigment container weighs:

60g

and you are using a:

500g scale

You place the container on the scale and press tare.

The display reads:

0.00g

But the scale is still physically supporting 60g.

You have approximately:

440g

of nominal physical capacity remaining.

Tare does not physically remove the container.

This is why capacity should always be calculated from the complete load.

11. Look for a Reliable Tare Function

Tare is essential for pigment formulation.

A basic workflow is:

Place your empty pigment container on the platform.
Allow the display to stabilize.
Press tare.
Confirm 0.00g.
Add your pigment.
Record the measurement.
Tare again if your workflow requires it.
Add the next ingredient.
Record the new amount.

This is far easier than manually subtracting the container weight after every measurement.

12. Repeatability Matters for Reproducing Colors

Suppose you create a successful resin color.

Your formula is:

Mixed resin: 100.00g

Blue mica: 0.65g

Pearl pigment: 0.30g

Metallic pigment: 0.15g

Total colorant: 1.10g

If you want to make the same color again next week, you need more than decimal places.

You need consistent measurements.

Repeatability becomes particularly important for:

Matching jewelry sets
Product batches
Customer color requests
Resin-art collections
Prototype development
Production formulas
Multi-pigment blends

If a scale gives noticeably different readings for the same stable object, investigate the environment, batteries, loading, calibration and condition of the instrument.

AWS discusses these factors in Why Does My Digital Scale Give Different Readings?.

13. Platform Size Matters

Do not focus only on capacity and readability.

Your container must fit correctly.

A suitable weighing container should:

Sit securely
Remain centered
Be fully supported
Avoid touching the counter
Avoid touching the scale housing
Leave the display visible

If part of the container rests on another surface, the scale is no longer supporting the complete load.

That can interfere with the measurement.

Before buying a scale, measure the cups and trays you actually plan to use.

14. Choose a Display You Can See While Pouring

Pigment containers can obscure small displays.

Look for:

Backlighting
Clear decimal points
Large enough digits
Good viewing angle
Display placement that remains visible

This is especially important with 0.01g and 0.001g scales because accidentally reading the decimal incorrectly can significantly change a small formulation.

15. Calibration Should Be Straightforward

A good pigment scale should have a clearly documented calibration or performance-check procedure.

There is no universal calibration process for every digital scale.

Different models may require:

Different calibration weights
Different button combinations
Different warm-up periods
Different calibration sequences

AWS provides a complete explanation in How to Calibrate a Digital Scale for Accurate Results.

Always follow the procedure for your exact scale model.

For additional measurement-science context, NIST's Calibration Procedures for Weights and Measures Laboratories describes standardized calibration procedures designed to support traceability and understood measurement uncertainty.

Your resin workstation does not need laboratory-level procedures, but the underlying principle remains relevant:

use an appropriate reference and a defined procedure.

16. Do Not Calibrate With Random Household Objects

Do not substitute:

Coins
Resin bottles
Pigment jars
Tools
Jewelry
Cured resin
Kitchen utensils

for the manufacturer's specified calibration reference.

Use the calibration mass specified for the exact scale.

NIST's Selected Laboratory and Measurement Practices and Procedures to Support Basic Mass Calibrations provides broader technical context on good mass-measurement and calibration practices.

17. Consider the Weighing Surface

Pigment work can be messy.

Mica powder can spread easily.

Liquid pigments can drip.

Resin can damage a scale if it reaches sensitive areas.

A smooth weighing platform—often stainless steel on precision pocket scales—can make routine surface cleaning easier.

Still, prevent uncured resin and loose pigment from entering:

Button gaps
Electronics
Display seams
Battery compartments
Charging ports
Platform openings

Use a removable tray where appropriate.

18. A Tray or Protective Cover Can Be Very Useful

Some precision scales include covers that double as weighing trays.

Others include separate expansion trays.

These can be useful for:

Mica powder
Metallic pigments
Glitter
Lightweight additives
Small pigment containers

The tray itself still counts toward physical capacity.

Place it on the scale first and tare it before adding your material.

19. Use a Hard, Level Surface

A 0.01g precision scale should be used on a:

hard, rigid, stable surface

Avoid:

Towels
Fabric
Foam
Flexible silicone mats
Wobbly tables
Flexible shelves

The finer your measurement range becomes, the more important environmental stability becomes.

20. Avoid Airflow

Lightweight pigments and precision scales are both sensitive to air movement.

Avoid measuring directly beside:

Fans
Open windows
HVAC vents
Air purifiers
Strong air-conditioning airflow

Wait for the display to stabilize before recording the measurement.

This becomes particularly important with 0.001g scales.

21. Avoid Vibration

Vibration can come from:

Sanders
Drills
Compressors
Rotary tools
Speakers
Nearby machinery
Foot traffic
Flexible workbenches

If you are measuring a small quantity of pigment, perform precision weighing before operating nearby vibrating equipment.

22. Temperature and Static Can Matter

Fine-resolution measurement can also be influenced by environmental conditions.

Allow a scale to acclimate if it has been moved from:

A hot garage
A cold vehicle
An outdoor environment
A significantly different room temperature

Lightweight powders can also be difficult to handle when static is present.

The finer the measurement, the more carefully the environment should be controlled.

23. Decide Whether You Need Battery or AC Power

For a portable pigment station, batteries can be convenient.

For a permanent formulation bench, AC power may be useful.

Battery Power Is Useful For:

Portability
Flexible placement
Small workspaces
Occasional use
Easy storage

AC Power Is Useful For:

Permanent workstations
Frequent weighing
Production environments
Long formulation sessions

Choose according to how you actually work rather than treating one power source as universally better.

24. Consider Whether You Need One Scale or Two

This is one of the most important decisions.

A 500g × 0.01g precision scale may be excellent for pigments.

It cannot support a 2kg resin batch.

A 5kg scale may be excellent for large resin batches.

Its readability may be too coarse for tiny pigment quantities.

For makers who do both, two scales can be the better solution.

Main Resin Scale

Approximately:

2–5kg × 0.1g

Use for:

Resin
Hardener
Mixing containers
Medium molds
Coasters
Resin art

Pigment Scale

Approximately:

100–500g × 0.01g

Use for:

Mica
Pigments
Colorants
Metallic powders
Lightweight additives
Formula testing

AWS's Best Digital Scale for Resin explains why these two measurement ranges can complement each other.

25. Choose a Scale That Helps You Record Formulas

One of the biggest benefits of weighing pigments is repeatability.

Instead of writing:

“one scoop of blue”

you can record:

Blue mica: 0.72g

Instead of:

“a little silver”

you can record:

Silver pigment: 0.18g

A formulation record might look like this:

Component	Mass
Mixed resin	100.00g
Blue mica	0.72g
Pearl pigment	0.25g
Silver pigment	0.18g
Glitter	0.40g

This provides a much more useful reference for recreating the color later.

26. Follow the Pigment Manufacturer's Loading Instructions

Precision does not mean you can add unlimited pigment.

The appropriate pigment concentration depends on:

Pigment type
Pigment concentration
Resin system
Desired opacity
Manufacturer recommendations

Adding excessive colorant can affect the final resin system.

Use the instructions supplied by the pigment and resin manufacturers rather than assuming that every mica, paste, dye or liquid pigment should be used at the same percentage.

For broader educational context on pigment loading and how different colorant types behave in epoxy, Epoxy Guide's epoxy pigment and dye overview discusses mica, pigment pastes and other colorant types.

27. Do Not Confuse Pigment Measurement With the Epoxy Mixing Ratio

Your pigment scale measures mass.

It does not determine the correct resin-to-hardener ratio.

If you also use the scale to weigh epoxy resin and hardener, follow the exact manufacturer's instructions for that resin system.

A ratio given:

by volume

is not automatically numerically identical to the ratio:

by weight

because Part A and Part B can have different densities.

The correct ratio must come from the exact epoxy manufacturer's instructions.

For additional technical background on measurement requirements for weighing devices, NIST Handbook 44 provides specifications, tolerances and technical requirements used in weighing and measuring applications.

For hobby resin work, however, you should rely on the specifications and instructions for your actual scale and resin system rather than treating commercial weighing regulations as a requirement for craft use.

28. Best Scale for Mica Powder

For many mica powder applications, consider:

100–500g × 0.01g

This range gives you fine displayed increments without the extreme sensitivity of a milligram scale.

If you routinely use several grams of mica at a time and hundredth-of-a-gram control is unnecessary, 0.1g may be sufficient.

Choose according to your real formula.

29. Best Scale for Concentrated Resin Pigment

Concentrated colorants can be used in relatively small quantities.

If your measurements regularly fall below 1g:

0.01g readability

can be particularly useful.

For example:

0.35g

is easier to document on a 0.01g scale than on a scale displaying only tenths of a gram.

If quantities fall into the tens-of-milligrams range, investigate whether a 0.001g scale is actually necessary.

30. Best Scale for Metallic Pigments

Metallic powders can vary greatly in typical usage quantity.

Do not assume that every metallic pigment requires the same precision.

If your formula uses:

3.5g

0.1g may provide enough displayed detail.

If your formula uses:

0.35g

0.01g becomes much more useful.

Again:

Choose the scale according to the quantity.

31. Best Scale for Resin Jewelry Pigments

Resin jewelry often combines:

Small resin batches
Small molds
Mica powder
Concentrated colorants
Glitter
Metallic additives

This makes:

500g × 0.01g

an especially versatile specification.

The same scale may be able to handle both the small resin sample and its pigments while maintaining fine displayed increments.

For larger jewelry batches, you may still prefer a separate 0.1g scale with more capacity.

32. How to Test Whether Your Current Scale Is Good Enough

Before replacing your existing scale, evaluate it.

Ask:

Can it display the quantities I actually use?

If your pigment quantity is normally 0.35g and the scale reads only whole grams, it is too coarse.

Does the reading stabilize?

A constantly drifting display makes fine formulation difficult.

Does it repeat?

Place the same stable reference on the scale several times under the same conditions.

Is there enough capacity?

Include the container.

Does the container fit?

The entire load should be properly supported.

Can the scale be checked or calibrated?

Follow the manufacturer's instructions.

If your current scale performs well for your actual pigment quantities, you may not need additional resolution.

33. Common Mistakes When Choosing an Epoxy Pigment Scale

Choosing by Decimal Places Alone

More decimal places do not automatically mean better performance.

Assuming 0.01g Means ±0.01g Accuracy

Readability and accuracy are separate specifications.

Ignoring Minimum Load

Very small quantities require an appropriate usable weighing range.

Buying Too Little Capacity

Include your container and any resin sample.

Assuming Tare Restores Capacity

It does not.

Buying an Extremely Small Platform

Check your real containers first.

Ignoring Repeatability

Color formulation depends on being able to reproduce measurements.

Ignoring Calibration

Know how the scale should be checked.

Using Random Objects as Calibration References

Use the specified calibration weight.

Working Beside a Fan

Air movement can affect fine measurements.

Using a Flexible Work Surface

Use a rigid, stable surface.

Ignoring Vibration

Precision scales need a stable environment.

Choosing 0.001g When You Only Need 0.01g

Extra resolution can introduce unnecessary sensitivity.

Using One Scale for Every Possible Resin Task

Separate pigment and resin scales may provide a better working range.

Frequently Asked Questions

What scale should I use for epoxy pigments?

For many applications, start with a precision scale around:

100–500g × 0.01g

This provides useful capacity for small containers while displaying measurements in hundredths of a gram.

Is 0.01g good for epoxy pigment?

Yes, particularly when pigment quantities regularly fall below 1g or you want to document repeatable color formulations.

Is 0.1g enough for mica powder?

It can be if your mica quantities are relatively large and 0.1g increments provide sufficient detail.

For smaller formulas, 0.01g may be more useful.

Do I need a 0.001g scale?

Usually not for ordinary resin pigment work.

Choose 0.001g when the actual quantities you need to measure require milligram-level readability.

Is 500g × 0.01g a good choice?

For many resin makers, yes.

It combines enough capacity for small containers and resin samples with hundredth-of-a-gram readability.

What does 500g × 0.01g mean?

The scale has a maximum capacity of 500g and displays measurements in increments of 0.01g.

Does 0.01g mean ±0.01g accuracy?

No.

0.01g describes readability.

Check the manufacturer's accuracy, tolerance, minimum-load and repeatability specifications separately.

Does tare increase scale capacity?

No.

Tare changes the displayed value but the container still contributes to the physical load.

Should I choose a pocket scale for pigments?

A precision pocket scale can be very practical for pigments because compact scales are commonly available with 0.01g readability.

Make sure the platform is large enough for your containers.

Should I calibrate my pigment scale?

Follow the manufacturer's instructions for checking and calibrating your exact model.

Can I calibrate it with coins?

Use the calibration reference specified by the scale manufacturer rather than random household objects.

Why does my scale fluctuate when weighing mica?

Possible causes include:

Airflow
Vibration
Static
Temperature changes
Weak batteries
Unstable surfaces
Off-center loading
Calibration issues

Should I buy separate scales for resin and pigment?

If you work with both large resin batches and sub-gram pigment quantities, two scales can be more practical.

Consider:

2–5kg × 0.1g for resin

and:

100–500g × 0.01g for pigments

Final Verdict: How to Choose a Scale for Epoxy Pigments

Start with the smallest amount of pigment you actually need to measure.

Do not start with the number of decimal places.

If your pigment quantities are several grams and small differences are unimportant:

0.1g may be sufficient.

If your pigments regularly fall below 1g or you want more detailed, repeatable color formulas:

0.01g is often the better choice.

If your actual formulation requires milligram-level quantities:

investigate 0.001g equipment.

Then calculate capacity from:

container + resin sample + pigment + additives

For many resin pigment applications:

100–500g capacity × 0.01g readability

is a practical range.

500g × 0.01g

scale can be particularly versatile because it provides enough capacity for many small containers and resin samples while maintaining hundredth-of-a-gram readability.

But do not stop at capacity and readability.

Evaluate:

Accuracy specifications
Repeatability
Minimum usable load
Tare
Calibration
Platform size
Display visibility
Power source
Environmental stability

And remember:

Readability is not accuracy.

Tare does not increase physical capacity.

0.001g is not automatically better than 0.01g.

The best scale is the one whose measurement range matches your actual pigment quantities.

If you work with both pigments and larger resin batches, a two-scale setup can be especially practical:

2–5kg × 0.1g for resin and hardener

plus:

100–500g × 0.01g for pigments and additives

That gives you capacity where you need it and finer measurement where it actually matters.
