Sabbir Posted April 17, 2020 Report Share Posted April 17, 2020 Hi guyz, Now i want to share a glaze recipe with you, If you want to transparent glaze on your pottery you can use this recipe, i showed a figure which body color is gray so its show gray color, if you applied it on white body it will look so gorgeous. Soda feldspar: 5% Potash feldspar: 31% Quartz: 30% China clay: 6% Calcium carbonate: 13% Barium carbonate: 4% zinc oxide: 10% Talc: 1% Try& share it.. #stay_home & stay safe from covid-19. Thank you Link to comment Share on other sites More sharing options...
neilestrick Posted April 17, 2020 Report Share Posted April 17, 2020 @Sabbir What temp/cone is this recipe for? Link to comment Share on other sites More sharing options...
Hulk Posted April 17, 2020 Report Share Posted April 17, 2020 Two issues I'm working on for mid fire (cone 6) clear glazes, i) micro bubbles, red and black clays and ii) crazing, buff, white and light red clays - have a good solution for first, working on the second. I'm not seeing any barium carbonate in my future... https://ceramicartsnetwork.org/daily/ceramic-glaze-recipes/glaze-chemistry/leaving-bariumville-replacing-barium-carbonate-in-cone-10-glazes/ https://digitalfire.com/4sight/hazards/ceramic_hazard_barium_in_materials_and_fired_glazes_26.html That's a good looking pedestal sink!

Have you looked into the much less reactive but related strontium carbonate? Link to comment Share on other sites More sharing options...
Sabbir Posted April 18, 2020 Author Report Share Posted April 18, 2020 @neilestrick i used this glaze recipe at 1205 ℃ Link to comment Share on other sites More sharing options...
Mark C. Posted April 18, 2020 Report Share Posted April 18, 2020 I'm a high fire guy why add Barium carbonate: 4% to a cone 6 clear?/ Clears can be had without any Barium carbonate I'm sure. especially for sanitary wares But Thanks for sharing the glaze looks great on that pedestal sink Link to comment Share on other sites More sharing options...

A bit o' lithium via petalite is what I'm looking into for second problem (crazing, clear glaze, cone 6, some, not all clays), also a small amount of zirconium and tweaks to recipe. To the op, thanks for the mid fire recipe. I'm not interested in barium at this time. Link to comment Share on other sites More sharing options...
Rae Reich Posted April 19, 2020 Report Share Posted April 19, 2020 The book referenced the CM article in @Hulk's post, James Chappell’s The Potter’s Complete Book of Clay and Glazes, is very useful for finding alternate glazes to get the effect you want at the temp you want - highly recommended! Interesting article. Link to comment Share on other sites More sharing options...

Hulk Posted April 19, 2020 Report Share Posted April 19, 2020 My latest iteration of low expansion clear's coe < 5.7 (per GlazeMaster), still crazing, already have some Magnesium (from talc) in there, low sodium - looking to go lower coe. As for new/other recipes, some notes might be helpful, e.g. was developed to resolve specific issues a,b,c; includes ingredients because logical explanation ab,c; behaves with specific clay(s) as described; usage and application notes a,b,c; is sensitive to a,b,c ...and etc., etc. Link to comment Share on other sites More sharing options...

Adjusting COE with different materials has its challenges. Just wondered if you had explored taking your existing recipe and adjusting RO and total alumina per Her research. Just an idea.
