I came to Idyllwild with three dear San Diego friends, Merle, Sandra and Danae, all with various expectations, from learning how to mix glazes to how to create a new glaze. There we rekindled with Harriet, whom Merle, Danae, and I had met last year at the Soda Firing workshop. And we made new pottery friends in the process. That's how it works at Idyllwild ! Oh, and the food on campus was excellent. Buffet style, and ice cream every day. And those almond cookies were to die for !

Overall, I think we all met our goals. Personally, I was interested in learning the process of creating a glaze from any kind of ashes. Ashes contain all the ingredients necessary for a glaze (fluxes, alumina, silica), it is simply a matter of finding out the right melting combination. I had brought some oak ash, previously sieved. A melt test with different fluxes and frits narrowed it down to a basic recipe to explore. Tweaking the melt to give a stable glossy glaze at cone 6-7 was then quickly achieved with the help of silica and EPK. With a recipe in hand for my oak ash, I can now explore different colors with oxides and stains, as well as varying the opacity of the glaze. Exciting !

The class also gave me the opportunity to try out new glazes from the a few books I brought, thanks to the full access of chemicals at the ceramics studio. That's more than what I have at home, but I know now what else I should procure for my own studio. Notably a particularly useful barium frit, Ferro Frit fb284m, which alleviates the manipulation of the harmful barium carbonate.
