  1. A lovely blue glaze that breaks to a golden brown that our community studio loves. Needs to be applied rather thick but is also a runner so careful application is necessary. The last batch that was mixed turned out to be a transparent honey brown and we are calling caramel for lack of a better word. Re-tested - same results. Re-tested again using the 3 frits that we store in large containers thinking maybe the wrong frit was used - same results. We are stumped. The Alberta Slip is from a bag we have had for some time. The rutile may be from a new bag. Any suggestions. Thanks so much for your help. I am not a glaze specialist - give me a recipe and I am good. 80% Alberta Slip 20% 3134 Frit 5% Rutile
  2. Thanks, I will order a small amount of the Gillespie and give it a test.
  3. I have tried reducing the Rutile to get a more blue look as it was looking rather green at one point. When doing that, should the other colorants be reduced as well? Also, what are the issues with the Gerstley? Thanks so much for your input - I value it all as I am certainly no glaze expert.
  4. Thanks for the tips. I have tried soaking and that did not seem to solve the problem. Do you have a blue recipe that I can test that you would be willing to share. I am, by no means, a glaze expert - following a recipe is pretty much the extent of my knowledge. Thanks for your help.
  5. Hey everyone. I need some help with a cone 6 Blue Hare's Fur recipe. Nephaline Syenite 47.30 Laguna Borate (Gerstley) 27.00 Silica 20.30 EPK 5.40 100.00 RIO 2.00 Cobalt Oxide 1.00 Rutile 4.00 Bentonite 2.00 I teach at a community studio in Vernon, BC. Our Blue Hare's Fur recipe was one of our most popular and stable glazes but in the last year or so has been pitting. We have re-mixed and no luck. It is the only glaze that we are having trouble with - all others are fine. Had the same issues with Floating Blue. Members are crying for a blue - what do I do..... Thanks for your help.
  6. Yes, the color of the first piece is wonderful and we love the glaze and we are very sad that we seem to have lost it. The recipe comes from the ceramics handbook Glazes Cone 6 by Michael Bailey. We used a potash feldspar. If you test it, please let me know the results.
  7. Our Orange Red - OR cone 6 glaze recipe is now turning out a very sad, plain brown. The recipe is: Potash Feldspar - 46.7% China Clay - 4% Bentonite - 2% Bone Ash - 15% Lithium Carbonate - 4% Talc - 16.9% Fling - 11.4% Red Iron Oxide 11.5% Does anyone know if the make-up of any of the ingredients has changed or what might be the problem for us? The firing is taking almost 15 hours and we are allowing a natural cooldown. The cones (5, 6 & 7) were all totally bent. Someone told me that this may not actually be an overfire but is possibly that the firing took too long. May timing be the problem? In the last firing we had one piece that was sprayed with an old mix of the glaze and it turned out ok but the new mix did not. This is the lovely OR we had in the past: And this is what we are getting now: www.VernonCommunityPotters.wordpress.com
