Kristine posted a topic in Clay and Glaze ChemistryI have recently set up my own studio, but lack knowledge in the area of firing . I have found some great cone 6 glaze recipes but have not been able to find a commercial cone 6 clay. Before I experiment and do something which might damage my kiln I wonder if anyone has any experience in doing this. It is my understanding that the cone 5 clay would likely fire to cone 6 and worst case scenario I might have some warping. Any recommendations?
