TEST COLORS
ca: PROVA DE COLORS
Test colors: keep a file on the all the colors you use, classifying them under the temperature at which they are fired. File the name of the color, where you buy it, the industrial names of the ingredients and the measurement of everything needed to make it, plus two fired samples of each color and a photo of the sample. To test colors, use a small piece of dry clay or bisque, prepare it with the color, code it on the back and fire it. Read more about: Color testing
