“A group of us has been experimenting with a new temperature this year,” said Colorado Potters Guild member Mary Lou Steenrod of Littleton. “We have been firing Cone 6 glazes in the gas kiln (instead of the electric kiln usually used for these lower temperatures).
“It gives us a new palette of colors,” she said, adding: “A number of pieces with these new colors will be included” in the guild’s Spring Show and Sale, scheduled May 2-4 at First Plymouth Congregational Church, she said.
She, personally, has been doing more work in porcelain, which she will also display.
She uses a combination of glazes available at the guild’s studio, such as a copper glaze is enhanced by use of wax resist and then the addition of a black glaze, which gives green color where the two blend together. Choices in glazes “depend on what you come up with that pleases you,” she said.
She works in her home studio in Roxborough Park, where she has a potter’s wheel, slab roller, electric and raku kilns. For gas firing, she uses the large kiln at the guild studio, which can involve a considerable time commitment, as firings take longer. It does give different colors with glazes and can go to the higher Cone 10 temperature, which allows different effects.
About 30 potters will exhibit and sell almost 2,500 pieces of original, handmade functional and sculptural pottery.
