  1. Hello all, Just inherited a 13litre tub of clear earthenware glaze (duncan). I'm not a studio potter, but a sculptor (ceramic). I'm dreaming of making lots of new glazes from this tub. So I'm looking for a list of additives ie. Silicon carbide to make it foam and thicken, Zirconium oxide to whiten, Tin to blush. I'll be adding oxides and stains. But I want more info on new weird behaving ingredients to test. Any other ideas folks? Thank you all for your expertise, your feedback has helped me learn so much : )
  2. I have a couple of buckets of unknown glaze materials. When I test fired them I got a very dry underfired result. Then I set about adding various materials, looking for what would make it fusible, something like a glaze. Testing systematically, I have added every material I have at hand and in combinations, such as, silica, feldspar, talc, whiting, gerstley borate, china clay, alumina, nepheline syenite, borax, rutile, and so on, at various quantities 10, 20 %. I can not get much of a change, and it has got me beat. Surely something has to give. Of course maybe if I added something at 50 to 100% I would get a change but this would be counter productive, adding a lot of material and just creating a double lot of some unknown recycled glaze, and not making primary use of this quantity of waste unknown material. At that rate I might as well discard the waste glaze. But to actually find a solution, adding something in the order of 10 or 20 %, does anyone have any insights? I am quite amazed that I have not found any addition that works. I have tested at cone 1, 3, and 6. Of course it could be it needs a higher temperature, but that's not the point, because even a higher temperature glaze can be modified. The obvious additions just don't seem to be working. Let me put it this way. How can a mix of glaze material not be a glaze? For materials which generally are a glaze, which ones when added together will not act like a glaze? A strange question? Any thoughts?
