CMW Team Visits Fiesta Dinnerware – Part 1
The CMW team recently had the opportunity to visit Fiesta Tableware in Newell, WV. It was a thrill, as we always love visiting factories and seeing how they produce their ceramics. It is amazing that the way they work with clay is the same way the artist community...
More Talk About Tin…
More Tin talk...one more example of what Tin does. These are the same glaze, again made without Tin on the right, adding Tin to the same batch on the left. This time, the glaze is just increasing the level of opacity. As we said in earlier post today, when we opacify...
Conversations about Tin Oxide (SnO2) – Part I
Reduction is a new concept for a lot of people, that’s because the majority of people are firing in electric kilns, which basically only fire in Oxidation (there are some ways to do it, but they aren’t the safest or most stable). Most people think about Reduction in...
Conversations about Tin Oxide (SnO2) – Part II
Continuing on the conversation about Tin! Copper Red glazes are interesting as they often contain a lot more Tin than Copper. We’ve seen formula that will have 0.5% Copper and 6x or more Tin. These two glazes are from the same batch. The tile on the right is without...
Getting boron levels right
When we talk about converting a glaze from Cone 10 to cone 6, we need to have a precise understanding of our chemistry. First we need to understand what materials we are using to get the temperature down. The majority of the time, the best option is Boron. We find...
