Guest posted a topic in Ceramic Events of InterestUNDERSTANDING GLAZE CHEMISTRY WORKSHOP (CER074SA) Sharon Campus of New Hampshire Institute of Art Nov 12 (Saturday), 10am â€“ 3pm Professor John Baymore $129 This one-day seminar workshop will provide participants with a basic understanding of the core concepts that can impact the creation, use, and evaluation of ceramic glazes for studio use. The use of the popular Insight ceramic chemistry calculation software will be introduced, and the approach used to this can be applied to any ceramic chemistry software. Troubleshooting of fired results, "food-safe" qualities, health and safety, legal requirements, and ventilation concepts will also be touched upon. Handouts will be provided to all participants.

hey all, I'm determined to work with cobalt and get detailed brush strokes on an opaque white background. I'm interested in Delftware, Chinese blue and white pottery, etc. I keep having issues with the glazes and I keep trying different ones and combos and I'm not getting anywhere. This technique/aesthetic seems so classic and universal that this shouldn't be so hard, and I shouldn't have to keep reinventing the wheel! Would anyone be able talk with me about this? - - - Specifically, I'm using low fire majolica process for it's simplicity (i'm using this recipe: http://digitalfire.com/4sight/education/g1916m_cone_06-04_base_glaze_226.html?logout=yes), but the cobalt which is mixed 1:1 with non-opacified base glaze, is either chalky and almost unmelted in heavy/dark areas and in other random seeming areas the cobalt seems to bleed out onto the background. I'm looking to have relatively sharp/clean lines and brushstrokes, a more even, smooth texture (not the hard buildup in the darkest areas). - - - I'm ready to head to Delft, NL and beg the folks at Royal Delft Blue to explain to me what they're doing. Someone, please! How is this done? (p.s. don't know why CAD rotated this image, but it did. Sorry)
