  1. glaze help!

    So if you can't find it commercially then why not try mixing one yourself. What you could do if you want to give it shot at mixing your own is take a Celedon recipe, such as Pinnell Celadon, and remove the opacifiers and colorants. This glaze is a very nice transparent celadon so altering it to a clear would make a very nice smooth clear. Pinnell Celadon Custer Feldspar 24.50g Silica 34.30g Whiting 19.60g Grolleg Kaolin 19.60g Barium Carb. 1.90g Tin Ox. 1.00g Yellow Iron ox. 0.50g So if you remove the Yellow iron and the Tin from that recipe you should end up with a nice clear. Also Barium can be substituted 1:1 with Strontium Carbonate. This glaze is very stable and doesn't crawl or pinhole. I know in the states this is a very affordable glaze to put together minus the Tin which you wont need anyway. Hope this was helpful, i dont think i missed anything in terms of the chemistry but mixing up a few test batches 100-200g couldn't hurt. example clear Custer Feldspar 24.50g Silica 34.30g Whiting 19.60g Grolleg Kaolin 19.60g Strontium carb. 1.90g Total 99.9%
  2. Nelly, Ive had the best results with this technique using a porcelain slip, more specifically from a porcelain body that uses soda feldspar such as Helios. Using that epsom salt mixture reconstitutes the soda back into the deflocculated slip so it holds up nicely when applied and gives that full bodied fluffy look that Steven Hill gets. As for your slip, i don't think you made something that wont hold a glaze. I have never had a problem with that solution effecting my glazes negatively so im pretty sure you wont have any problems. Hope I was able to give some useful info, good luck
