Dry paint in a 2-dram glass vial (average weight varies by color). Mix with media, apply to bisque, and fire to Cone 018.
Add MATTER to your gloss china paint for a more satin finished look. A little bit goes a long way. You can experiment with different intensities and fire samples to determine the right mixture for the effect you desire. A good starting point is 1 part MATTER to 3 parts of a gloss color, or 1 part MATTER to 4 parts of a gloss color.
