Epoxy Pigments Scale Buying Guide: Accuracy, Capacity and Calibration

Posted by AWS Team on Sep 2nd 2026

Choosing the right scale for epoxy pigments is about more than finding a model that displays two or three decimal places.

A good pigment scale needs the right balance of:

accuracy, capacity, readability, repeatability and calibration capability.

For many resin artists, a practical starting specification is:

100–500g capacity × 0.01g readability

A 500g × 0.01g scale can be especially versatile because it provides fine displayed increments while leaving enough capacity for pigment cups, small resin samples, trays and multiple additives.

But the best scale depends on what you actually measure.

If your pigment quantities are several grams, 0.1g may be enough.

If you regularly work below 1g, 0.01g becomes much more useful.

If your actual formulation involves milligram-level quantities, 0.001g may be necessary.

This buying guide explains how to evaluate the specifications that matter before choosing an epoxy pigment scale.

Quick Buying Guide

Application	Suggested Capacity	Suggested Readability
General mica powder	100–500g	0.01g
Concentrated resin pigments	100–500g	0.01g
Small pigment formulas	100–500g	0.01g
Metallic powders	100–500g	0.01g
Glitter	200–500g	0.01–0.1g
Resin jewelry pigments	200–500g	0.01g
Small resin samples	200–500g	0.01g
Larger additives	500g+	0.1g where appropriate
Milligram-level ingredients	Application-specific	0.001g when required

For many pigment-focused workflows, 500g × 0.01g offers one of the most useful combinations of capacity and fine readability.

AWS explains exactly what those two numbers mean in What Does 500g × 0.01g Mean on a Digital Scale?.

1. Accuracy Should Come Before Extra Decimal Places

When people shop for a precision pigment scale, they often focus immediately on:

0.1g

0.01g

or:

0.001g

But those numbers describe readability.

They do not tell you everything about measurement performance.

A scale displaying:

0.37g

has 0.01g readability.

That does not automatically mean every measurement is guaranteed accurate to exactly ±0.01g.

When evaluating a scale, consider:

Readability
Accuracy specification
Repeatability
Minimum usable load
Calibration procedure
Capacity
Environmental sensitivity
Proper loading

This distinction becomes especially important when weighing small quantities of concentrated pigment.

NIST describes calibration in terms of establishing a mass value together with an appropriate uncertainty, illustrating why dependable measurement requires more than simply displaying additional decimal places. Learn more from NIST's Calibration of Mass Standards program.

2. What Is Readability?

Readability is the smallest increment the scale displays.

0.1g scale

might display:

1.2g

0.01g scale

might display:

1.27g

0.001g scale

might display:

1.274g

More readability gives you finer displayed detail.

It does not automatically mean the scale is better for your application.

The goal is to choose the level of readability appropriate for the smallest meaningful quantity you need to measure.

3. Is 0.1g Enough for Epoxy Pigments?

Sometimes.

A 0.1g scale can work well when your normal pigment quantities are relatively large.

For example:

4.5g

8.2g

12.7g

In those situations, hundredth-of-a-gram resolution may provide little practical benefit.

0.1g may also be preferable if you need considerably more capacity for resin, hardener and larger containers.

For dedicated small-pigment work, however, 0.01g is often more useful.

4. When Is 0.01g Better?

A 0.01g scale displays hundredths of a gram.

That can be especially useful when weighing quantities such as:

0.25g

0.48g

0.72g

1.35g

Common applications include:

Mica powder
Concentrated pigments
Small resin additives
Metallic powders
Jewelry color formulas
Small test batches
Multi-pigment blends

If you want to document a successful resin color and reproduce it later, 0.01g can provide significantly more useful detail than 0.1g.

AWS's 0.001g vs. 0.01g Scales guide explains how these finer readability ranges differ.

5. Do You Need 0.001g?

Usually not for ordinary epoxy pigment work.

A 0.001g scale displays:

one milligram

That means it can show readings such as:

0.125g

0.126g

0.127g

This can be valuable when your formulation genuinely requires quantities measured in thousandths of a gram.

However, finer-resolution scales are also more sensitive to environmental factors.

These may include:

Drafts
Vibration
Static
Temperature
Surface movement
Off-center loads

If your typical pigment quantity is:

0.65g

you probably do not need to buy a milligram scale simply because it displays another decimal place.

Choose 0.001g only when the actual application requires it.

6. Repeatability Is Critical for Pigment Formulation

Accuracy matters, but repeatability is also extremely important.

Suppose you create a color using:

Mixed resin: 75.00g

Blue mica: 0.46g

Pearl pigment: 0.24g

Silver pigment: 0.18g

A scale that provides stable, repeatable readings gives you a much stronger foundation for recreating that same formulation later.

Repeatability matters for:

Resin jewelry collections
Product batches
Custom colors
Prototype development
Customer orders
Formula documentation

If the same stable load produces noticeably different readings repeatedly, investigate your setup before assuming the pigment formula is the problem.

AWS covers common causes in Why Does My Digital Scale Give Different Readings?.

7. Minimum Usable Load Matters More Than Many Buyers Realize

This specification is especially relevant for epoxy pigments.

A scale may be labeled:

500g × 0.01g

but the smallest displayed increment is not necessarily the same as the smallest ideal working load.

If your ingredient quantity is extremely small, check any available manufacturer specifications for:

Minimum load
Accuracy
Repeatability
Tolerance

This becomes increasingly important as your samples approach the bottom of the scale's useful measurement range.

Do not assume a scale displaying 0.01g is automatically optimized for weighing exactly 0.01g.

8. Capacity Is the Other Half of the Decision

Pigments are light.

Your entire weighing setup may not be.

Capacity includes everything sitting on the platform.

That can include:

container + resin sample + pigment + additives

Suppose:

Container = 45g

Resin sample = 120g

Pigments = 2g

Other additives = 3g

Total physical load:

170g

A 100g scale would be unsuitable.

A 200g scale could technically support the example but would provide limited headroom.

A 500g scale would give you significantly more flexibility.

9. Why 500g Is a Practical Capacity for Pigment Work

For many resin makers, a 500g precision scale can accommodate:

Small pigment containers
Weighing trays
Resin samples
Jewelry-sized batches
Multiple pigment additions
Mica powder
Glitter
Metallic powders

Combined with 0.01g readability, it provides a useful working range without forcing you into a very low-capacity scale.

That is why 500g × 0.01g is such a common and practical specification for fine craft measurements.

10. Capacity Includes the Container

This is one of the easiest specifications to misunderstand.

Suppose you have:

500g maximum capacity

and your cup weighs:

60g

You put the cup on the platform and press tare.

The scale displays:

0.00g

However, the scale is still physically supporting 60g.

Approximately:

440g

of nominal capacity remains.

Tare does not restore physical capacity.

11. Leave Capacity Headroom

It is usually better to choose enough capacity so that your normal workflow does not constantly bring you close to the maximum load.

If your typical complete load is:

180g

a 200g scale may technically be enough.

But a 500g scale provides much more flexibility for:

Different cups
Larger samples
Additional additives
Future projects

Choose capacity based on realistic use rather than the smallest possible number.

12. Tare Is Essential

A pigment scale should include tare.

A typical workflow is:

Place the empty pigment cup on the scale.
Allow the reading to stabilize.
Press tare.
Confirm 0.00g.
Add Pigment A.
Record the mass.
Tare again if appropriate.
Add Pigment B.
Record the mass.
Continue until the formulation is complete.

This removes the need to manually subtract container weight during every measurement.

13. Calibration Capability Should Be Part of Your Buying Decision

A precision scale should provide a documented method for calibration or performance checking.

Different models can require different:

Calibration weights
Procedures
Button sequences
Setup conditions

Do not assume all 500g scales use the same calibration mass.

AWS explains the process in How to Calibrate a Digital Scale for Accurate Results.

For broader technical context, NIST also publishes calibration procedures used by weights-and-measures laboratories. See NIST Calibration Procedures for Weights and Measures Laboratories.

14. Use the Correct Calibration Weight

Do not calibrate your precision scale using:

Coins
Resin bottles
Pigment jars
Jewelry
Tools
Cured resin pieces
Random kitchen objects

Use the reference mass specified by the manufacturer for your exact model.

An object having an approximate advertised weight is not the same as using an appropriate calibration reference.

NIST's work on mass standards reinforces the broader measurement principle that reference masses need known values and uncertainties rather than assumptions based on ordinary household objects.

15. Calibration and Tare Are Not the Same Thing

This is another common misunderstanding.

Tare sets the displayed value to zero with a container or object on the scale.

Calibration adjusts or checks the scale's relationship to a known reference mass according to the manufacturer's procedure.

Pressing tare does not calibrate the scale.

Calibrating the scale does not eliminate the need to tare your container during normal weighing.

Both functions serve different purposes.

16. How Often Should You Calibrate a Pigment Scale?

There is no universal schedule that applies to every model and every workshop.

Follow the scale manufacturer's instructions.

It may be worth checking performance after situations such as:

Moving the scale
Long storage
Significant temperature changes
Accidental shock
Suspected measurement problems

Do not create an arbitrary calibration interval that contradicts the instructions supplied for your scale.

17. Calibration Requires a Stable Environment

Calibration should be performed under suitable conditions.

Use a:

hard, flat, stable surface

and avoid:

Airflow
Vibration
Temperature swings
Physical movement of the table

The same environmental factors that affect normal precision weighing can interfere with calibration.

18. Platform Size Matters

Capacity alone does not tell you whether your pigment cup will fit.

A suitable platform should allow your container to:

Sit securely
Remain centered
Be fully supported
Avoid touching the surrounding counter
Avoid touching other parts of the scale
Leave the display visible

Before buying, measure the containers you actually use.

A compact scale may have enough capacity but still have too little platform area for your workflow.

19. Stainless Steel Is Useful Around Pigments

Mica and resin work can be messy.

A stainless-steel weighing platform can be useful because it provides a smooth surface for routine cleaning.

However, do not allow uncured resin or pigment to enter:

Display seams
Buttons
Platform gaps
Battery compartments
Electronic components

Use weighing trays or disposable liners where appropriate and follow the manufacturer's cleaning instructions.

20. Trays and Protective Covers Add Practical Value

Precision pocket scales often include:

Protective covers
Expansion trays
Removable weighing trays

These can help contain:

Mica
Glitter
Metallic powders
Lightweight additives

If you use a tray, remember:

the tray counts toward scale capacity.

Place it on the platform and tare it before adding the material.

21. Display Quality Matters

When you are measuring 0.01g quantities, you need to see the decimal clearly.

Look for:

Backlighting
Clear digits
Visible decimal point
Useful viewing angle
Display placement that is not blocked by the cup

A scale with excellent specifications can still be inconvenient if the container constantly hides the display.

22. Stable Zero Is Important

Before adding pigment, the display should settle reliably.

If the empty scale fluctuates between:

0.00g

0.02g

-0.01g

0.03g

then weighing a 0.25g pigment quantity becomes difficult.

Possible causes include:

Drafts
Vibration
Weak batteries
Temperature changes
Static
Unstable work surfaces
Improper loading
Calibration issues

Evaluate the environment before assuming the scale itself is faulty.

23. Avoid Drafts

Fine-resolution scales react to forces that may seem insignificant.

Air movement can come from:

Fans
HVAC vents
Open windows
Air purifiers
Strong air conditioning

This is particularly relevant with mica powder because the material itself is also lightweight.

Perform precision weighing away from direct airflow.

24. Avoid Vibration

Precision measurement also requires a stable work surface.

Possible vibration sources include:

Sanders
Compressors
Rotary tools
Drills
Speakers
Machinery
Foot traffic

Turn nearby vibrating equipment off when performing fine pigment measurements whenever practical.

25. Temperature and Static Matter More as Readability Gets Finer

A scale that reads to 0.01g or 0.001g is more sensitive to environmental conditions than a typical whole-gram kitchen scale.

Allow the scale to acclimate if it has been moved from a significantly different temperature.

Static can also complicate handling very lightweight powders.

This is another reason not to buy 0.001g equipment unless your formulation actually requires that level of readability.

26. Battery or AC Power?

Both can work well.

Choose according to your workspace.

Battery Operation

Useful for:

Portable scales
Small studios
Flexible placement
Occasional use

AC Power

Useful for:

Permanent formulation stations
Frequent weighing
Long work sessions

Power source does not replace the need to evaluate accuracy, readability, capacity and calibration.

27. Should You Buy a Pocket Scale?

For pigment work, a precision pocket scale can be an excellent choice because these compact models frequently combine:

Low-to-medium capacity
0.01g readability
Tare
Compact storage
Protective covers
Small weighing trays

For larger resin batches, however, a higher-capacity scale may make more sense.

AWS compares these categories in Pocket Scale vs. Kitchen Scale: Which One Should You Buy?.

28. Do You Need One Scale or Two?

Many resin makers can benefit from separating pigment measurement from bulk resin measurement.

Precision Pigment Scale

A useful range is:

100–500g × 0.01g

Use it for:

Mica
Concentrated pigments
Metallic powders
Lightweight additives
Color formulation

Main Resin Scale

A useful general range is:

2–5kg × 0.1g

Use it for:

Resin
Hardener
Mixing containers
Larger batches

AWS's Best Digital Scale for Resin discusses why larger resin batches often benefit from higher capacity while pigments can benefit from finer readability.

29. Do Not Use Pigment Precision to Guess Your Epoxy Mixing Ratio

If your pigment scale is also used for resin and hardener, there is an important distinction.

Your scale tells you mass.

It does not tell you the correct resin-to-hardener ratio.

A resin system labeled:

2:1 by volume

does not automatically mean:

2:1 by weight.

Resin and hardener can have different densities.

TotalBoat's current guidance states that product-specific weight ratios should be used when mixing its epoxy systems by weight because weight and volume ratios can differ. See TotalBoat's guide to mixing epoxy by weight.

A current TotalBoat TableTop Epoxy technical sheet, for example, specifies 1:1 by volume but 1.2:1 by weight, demonstrating why the measurement basis must be checked for the exact product. See the TotalBoat TableTop Epoxy instructions.

Always follow the resin manufacturer's instructions for the exact epoxy system you are using.

30. Do Not Assume Every Pigment Uses the Same Loading Percentage

A scale can measure pigment accurately.

It cannot determine how much pigment should be added to a particular resin formulation.

Recommended loading can vary by:

Mica
Paste pigment
Liquid colorant
Dye
Metallic powder
Resin system
Manufacturer

Always follow the pigment and resin manufacturers' instructions.

If you record pigment as a percentage, define the basis consistently so that you can reproduce the formula later.

31. A Better Way to Record Pigment Formulas

Instead of recording:

“one scoop blue mica”

write:

Blue mica: 0.65g

Instead of:

“small amount of white”

write:

White pigment: 0.22g

For example:

Component	Mass
Mixed resin	100.00g
Blue mica	0.65g
Pearl pigment	0.28g
Metallic pigment	0.16g
Glitter	0.45g

This gives you a measurable reference for future batches.

A precision scale is particularly valuable when it helps turn a successful experiment into a repeatable formulation.

32. Best Capacity for Mica Powder

For many mica applications:

100–500g

provides an appropriate range.

A 100g scale may be enough if:

The tray is lightweight
Pigment is weighed separately
Resin samples are tiny

A 500g scale provides more flexibility if you want to weigh pigment directly into:

Larger pigment cups
Resin samples
Jewelry batches

For general versatility, 500g often offers better headroom.

33. Best Readability for Mica Powder

For many mica formulations:

0.01g

is useful.

It allows you to distinguish:

0.32g

from:

0.38g

rather than forcing both measurements into coarser tenths-of-a-gram increments.

If you normally use several grams of mica and smaller differences are not important, 0.1g may be sufficient.

34. Best Scale Range for Concentrated Pigments

Concentrated pigments are often used in smaller amounts.

A range around:

100–500g × 0.01g

can therefore be a strong starting point.

The 500g capacity provides room for the container while 0.01g readability provides useful displayed detail for sub-gram colorant quantities.

If the actual ingredient quantity becomes genuinely milligram-sized, investigate whether a 0.001g model is appropriate.

35. Best Scale Range for Resin Jewelry Pigments

Jewelry-sized resin work often benefits from:

200–500g capacity

combined with:

0.01g readability

because both resin and pigment quantities are relatively small.

This range can be useful for:

Earrings
Pendants
Charms
Small molds
Colored inclusions
Small resin samples

A 500g model provides more capacity flexibility if you also weigh the resin mixture on the same scale.

36. Price Should Not Be Your Only Buying Criterion

The cheapest precision scale is not necessarily the best value.

The most expensive scale is not automatically the correct one either.

Compare the specifications that matter:

Capacity
Readability
Accuracy
Repeatability
Minimum load
Calibration
Platform size
Power source
Display
Included trays
Warranty

A scale is a better purchase when its measurement range matches the work you actually perform.

Frequently Asked Questions

What is the best scale for epoxy pigments?

For many resin pigment applications, a scale around:

100–500g × 0.01g

provides a useful balance of fine readability and practical capacity.

Is 500g × 0.01g good for pigments?

Yes.

It offers hundredth-of-a-gram readability while leaving enough capacity for many pigment cups, trays and small resin samples.

Is 0.01g accurate enough for mica?

0.01g describes readability rather than guaranteed accuracy.

However, hundredth-of-a-gram readability is useful for many mica formulations, especially when quantities are below 1g.

Do I need 0.001g?

Usually not for ordinary epoxy pigment use.

Choose 0.001g when your actual ingredients require milligram-level measurement.

Is 0.1g enough?

It can be if your normal pigment quantities are several grams and hundredth-of-a-gram differences are not important.

What does minimum load mean?

It refers to the lower part of the scale's useful weighing range.

The smallest displayed increment is not necessarily the smallest ideal working quantity.

Why does repeatability matter?

Repeatable measurements help you recreate successful pigment formulations later.

Does tare increase capacity?

No.

Tare changes the display but the container continues to count toward physical capacity.

How much capacity should I leave?

Choose enough capacity that your normal complete load does not constantly approach the maximum limit.

Should my scale be calibratable?

A clearly documented calibration or checking procedure is valuable for precision weighing.

Can I use coins for calibration?

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

Does platform size affect accuracy?

The entire load should sit properly and securely on the platform without touching surrounding surfaces.

Why does my pigment scale drift?

Potential causes include airflow, vibration, weak batteries, temperature changes, static, unstable surfaces and calibration issues.

Can I use one scale for resin and pigment?

Yes, if your entire measurement range fits within its specifications.

For makers handling both sub-gram pigments and multi-kilogram resin batches, two scales may be more practical.

What two-scale setup should I consider?

A useful starting combination is:

100–500g × 0.01g for pigments

and:

2–5kg × 0.1g for resin and hardener

Final Verdict: How to Buy the Right Epoxy Pigment Scale

When comparing scales for epoxy pigments, evaluate three areas first:

accuracy-related performance, capacity and calibration.

Start with your smallest normal pigment quantity.

If your ingredients are generally several grams:

0.1g readability may be sufficient.

If you regularly measure sub-gram pigments:

0.01g is often the better choice.

If your formulation genuinely requires milligram-level quantities:

consider 0.001g equipment.

Then calculate capacity using:

container + resin sample + pigment + additives

For many pigment workflows:

100–500g × 0.01g

provides an effective balance.

500g × 0.01g

scale is especially versatile because it combines fine readability with enough capacity for many pigment containers and small resin samples.

But never purchase on capacity and decimal places alone.

Also compare:

accuracy specifications, repeatability, minimum usable load, tare, calibration, platform size, display visibility and environmental stability.

Use the correct calibration reference.

Place the scale on a hard, stable surface.

Keep it away from drafts and vibration.

And remember the three rules that prevent many scale-buying mistakes:

Readability is not automatically the same as accuracy.

Tare does not restore physical capacity.

More decimal places do not automatically make a scale better.

For makers handling both pigment formulas and larger epoxy pours, a two-scale system can provide the most practical measurement range:

100–500g × 0.01g precision scale for pigments

plus:

2–5kg × 0.1g scale for resin and hardener.

That gives you fine measurement where it matters while preserving the capacity required for larger mixing work.
