Stains, Underglazes, and Pigments

I have also been testing Velvet underglazes, stains, and making my own Talavera paints out of pigment and frit. As well as square test tiles, I made little goats and birds to test out these glazes.

I read online that a 50 50 mix of pigment and frit is ideal for the traditional terracotta paints I am testing.

The end result is not as bright as I expected, so I may try more pigment in the next batch.
Although the colors came out smooth and shiny, they are not as vibrant as I hoped.
