While colorful glazes on the outsides of pieces get lots of praise and glory, the transparent or white providing the functional surface on the insides of pieces often gets little attention. Really, what good is an attractive piece if the food surface is crazed, pinholed, blistered, leached, cutlery marked. This liner glaze, G2926B, is special at cone 6. It is a good example of how I found a recipe, recognized its potential and tuned and adjusted it to be better. It has proven itself as a base to host all manner of colorants, opacifiers and variegators. One of the reasons it is so widely used is that it has a story, it is well documented, with a code number that Google indexes. Drinking from a mug having a quality functional surface instills pride as its maker. And it minimizes complaints from customers.
