I had a very frustrating firing. I usually clean my studio, write emails, check on lists while my gas kiln is firing. On Monday, I threw some new work and made about a hundred Christmas ornaments. But, I kept delaying watching the kiln at the very end. I paid the price! Fired it just a bit too long. Three large casseroles had glazes that ran onto the kiln shelves. Ruined! Cracked! $200 potential dollars gone! Life of a potter.
