I hope Janice in NC will not mind if I forward this response to the whole
list, because it is an important thing to consider. One practical
compromise between highfire and lowfire is high-bisque/low-glaze. The wares
are bisqued to midrange or highfire temperatures, and then glazed at lowfire
temperatures. You get a strong body, but the full color range of lowfire.
The disadvantage is that glaze coating itself is still quite brittle and
chips easily. Quite a bit of commercial china is either
high-bisque/low-glaze, or else is high-fired with a clear glaze and then
low-fired with enamels and lusters. That is why the decoration starts to
wear off while the dish itself is still in good shape.
