  1. I can't find much information on this at all. From what I've gathered 1.4 to 1.5 is typical for a homemade glaze. I think I'm going to try testing different sp gr around that range. Someone help us!!
  2. I was about to ask the same question, instead I'll follow this topic
  3. I'm not sure about the kiln or the firing cycle but I will be sure to find out! I'm not in control of the kiln myself. The weird thing is that both of these glazes worked and didn't work in the same firing, which is why placement seems most likely.
  4. Thank you for the input. I will try increasing EPK and Silica!
  5. I'm back with more glaze issues what fun. I've made two white glazes, one a glossy white and the other a matte white. I will share the recipes used below. I'm having a lot of mixed results with each of them, which is confusing because it's coming from the same firing, same glaze batches and same number of dips... sometimes my designs done in oxides look melted and other times they come out crisp and clean as intended. This is the desired effect: These are the issues: (the lines are blurry and have this "melting" look issue) Glaze recipes used: - Glossy - Dolomite 4 Gerstley 26 Whiting 6 Minspar 31 EPK 8 Silica 25 Zircopax 12 Bentonite 2 - Matte - Zinc Oxide 8.6 EPK 15.4 Silica 5.6 Whiting 18.8 Feldspar 51.6 The glossy recipe was used at a previous studio and worked consistently, never had this melting look issue. The matte glaze recipe I just found online to try out. It seems that it could have more to do with where these pieces are placed in the kiln rather than the actual glaze but I'm not sure, I'm very new to making glazes so I'm looking for any advice. Thank you.
  6. Thank you for your help! I'm going to give this a try.
  7. Here's more natural light to show the glossiness. They are etched in with oxides over the glaze.
  8. Here's a better example with white clay, the speckled makes it appear more matte. Ideally I'd actually prefer a matte white glaze but this recipe worked well so wanted to stick with it until I'm able to learn how to achieve that.
  9. The original was a glossy white (second picture added)
  10. Yes it is cone 6. Do you recommend doubling the silica and alumina then?
  11. I've finally ventured to make my own white glaze and now I'm having issues with the oxides reacting to the glaze weirdly or the glaze is simply messed up somehow. I followed the recipe from a studio I had worked in previously and got different results when making it myself. I even had a pottery professor attempt to make the same glaze and she produced a similar result to my own ( the messed up one ). Please let me know if you have any insight. Thank you Here is a photo of the messed up glaze and the desired outcome.
  12. This is an example of the issue I'm running into.
  13. The wax gets the excess oxide off best, then I pat the oxide with toilet paper. Thank you for insight, this is quite helpful. I normally wax / wipe almost immediately and it works perfectly (with the handmade glazes)
