The slips and glazes shown on this website have been tested on Coleman Porcelain. This gives us a "base" color pallet for the true color of the finished slips and glaze combinations. Just like painting a wall - the color of a clay body will influence the finished color of your glazes.
The only real porcelain is made with Kaolin (not ball clay). And, real porcelain has a high percentage of silica (glass). This gives you a good "melt" with your glaze and gives the surface more depth. Where the glaze and the clay body meet is called the "interface" layer. This higher quality porcelain material fired to cone 10 makes sense when you factor in all the work it takes to create work in clay. The value of the material is a better match to the value of your investment.
Firing in an electric kiln is a different melt than firing in a gas kiln (reduction). Oxygen is readily available in an electric kiln. A lot of commercial dinnerware is fired to cone 10 in oxidation. Reduction firing is starving the kiln of oxygen forcing the heat to go into the clay body searching for more oxygen. Either atmosphere works well when your firing to cone 10.
