I've been working with my old glaze recipe that i call 301 Bristol Borate. In the Advancing Glaze class i decided to see how in this glaze silicon carbide would react as a reducing agent in combination with copper carbonate. I've neen running a lot experiments with varying mesh sizes, changing chemical ratios, varying amounts of copper carbonate, tin, titanium dioxide, bone ash, etc, etc, etc. These two tiles are glazed with the same batch glaze. The difference? Temperature-the tile on the left was quickly fired to cone 4 in 4.5 hours. The tile on the right was fired to cone 5 in 6.5 hours with a slow cooling. Chemistry is temperature and temperature is chemistry! I'm very grateful to be able to take classes from Matt and Rose Katz of Ceramic Materials Workshop. They have been teaching and guiding me to learn what can happen and why. I doubt i would have ventured down this road without taking classes from Ceramics Materials Workshop. I'm very excited to start experimenting how to apply these glazes to pieces. . . . #glazetesting #ceramicmaterialsworkshop #experiment #siliconcarbide #cone5 #electricfire #maker #handmade #potterslife #selfemployed #glazechemistry #glazemaking (at Gerton, North Carolina) https://www.instagram.com/p/CIUsTOyDpuj/?igshid=1v32u1acx7gn0
