1 to 2 teaspoons of mica powder per gallon of epoxy is the standard ratio for optimal color saturation.
Mica powder is a popular pigment for epoxy resin projects, offering vibrant colors and shimmer effects. The amount used can significantly impact the final appearance of your project.

This ratio can be adjusted based on desired opacity and color intensity.
