National Endowment for the Arts
The National Endowment for the Arts was established by Congress in 1965 as an independent agency of the federal government. To date, the NEA has awarded more than $4 billion to support artistic excellence, creativity, and innovation for the benefit of individuals and communities. The NEA extends its work through partnerships with state arts agencies, local leaders, other federal agencies, and the philanthropic sector.
I used Porcelaine 150 about 14 years ago on some glasses; they have been washed over and over in the dishwasher, and the color is still bright and beautiful. I did bake them in the oven as the directions specified. This is a great product!
I like the White Galaxy Marker very much for writing on dark paper, and I have used it to cover another color when I needed to disguise a mistake or simply change effect.
For example, I bought an ornament with name SCARLETT spelled on it and by covering the last 't', I was able to give this to someone with a cat named SCARLET.
If color to be covered is a paint or other pen color, that can make the other color "stain" the white marker tip. This can be avoided if one is sure first color is dry before trying to cover it with white.
