  1. Latest results. Added a good bit of acrylic glazing medium and a few drops of dish soap to make it more brushable and it really worked this time.
  2. I think it would help if I added some kind of bonding agent like a gum to help keep lay the layers down so they don't lift off when brushing. I make quite a few pots and I like to use the ones that I trimmed through/cracked for testing because it makes sense to me to use the glaze on actually pots because the glazes acts differently on different forms besides tiles. It also factors in how this glaze will react to a trimmed surface (usually pinholes) and a surface smoothed with a rib, how easy it is to apply on the banding wheel and how it will work on the underside of the footring. I would just hate to develop a glaze that worked well on a test tile but doesn't work for my tablewares. I never thought about leather hard glazing, will try that for sure.
  3. I've had problems with pouring and dipping in the past, even on bisque wares I could never get that smooth finish it usually ended up with lots of drips all over the piece and puddles. If I pour on the greenware it will always crack apart 100% of the time, my pieces are on the thinner side. Most of the time I just brush on a good 3-4 coats on the inside, set it aside then do the outside and usually everything is fine. (except this one) I have more test firing right now with thinner glaze so we'll see.
  4. So this is the result of the first recipe, the perfect shade of white for me, perfect gloss at ^6. Just one issue...Magnificent crawling. I applied it in the greenware state. The consistency was about thick as yoghurt and brushed on 2-3 coats. I noticed it didn't crawl in the thinner spots where I applied the glaze. Maybe it needed to be thinned down a little bit more and brushed on finer layers but I believe it could be from the high zinc content and maybe I fired the kiln too fast. Any tips for crawling?
  5. That glaze looks great! Thanks for sharing this recipe, I might just go with this if the glaze isn't how I imagined.
  6. What type of Frit would you recommend for this glaze? There's quite a few to pick from and I'm not quite sure. Also, is there a way to increase the pinholing in this? I know this is a defect but I would like to have this glaze good and smooth in the interiors and subtle pinholed on the exterior. Maybe increase the whiting? I think if the kaolin was increased the glaze would be more prone to shivering?
  7. Yeah I noticed that, what is it with tin oxide that makes it almost $30.00 per lbs. I wonder? I think I will also purchase the Zircopax too, I've heard it creates an industrial bright white also. So what would be the percentage of replacing the tin with Zircopax, maybe 8- 10%?
  8. Hello Everyone! This is my first official time at making a glaze from scratch. Its a simple white glaze from a Lucie Rie recipe, fired to ^6 oxidation 58 Soda Feldspar 14 China Clay 10 Zinc Oxide 10 Tin Oxide 8 Whiting 8 Flint Now I cant exactly find the ingredients listed on here but I think I've found the equivalents. Such as Minspar 200 (F4) , Kaolin, and Silica 325 mesh. So the recipe would look like this? 58 Minspar Feldspar 200 (F4) 14 Kaolin 10 Zinc Oxide 10 Tin Oxide 8 Whiting (calcium carbonate 325) 8 Silica (325 mesh) Does this look like it would work? I am hoping this will be a bright white stark white I can use on my creamy beige stoneware.
  9. The leaves are good on this one, the vine travels nicely. But the vase is a little skimpy, maybe a little bit sturdier on the bottom
