Compared to most crystalline glaze reci...Hi Carole,<br />Compared to most crystalline glaze recipes the DeBoos Number 84 is very well behaved in that it has some clay content and thus there is a little more alumina then the more difficult ones. The alumina will "tame" the tendency to run excessively, but the glaze will still move so you will have to allow for this when you glaze a piece, and you will need to ensure that you protect the kiln shelf from any glaze runs. Crystalline glazes really do have to be low in alumina and quite fluid for large crystals to develop. I would fire this glaze between cone 9 and cone 10 for good results. <br /><br />PeterPeterhttps://www.blogger.com/profile/03078608554226394069noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-17980608216138325922019-06-30T21:47:08.499+12:002019-06-30T21:47:08.499+12:00Hello Peter,I'm interested to know if you were...Hello Peter,I'm interested to know if you were able to achieve a non runny result with DeBoos No.84. Some years ago I put a test into the kiln at our Art Centre in Perth in Western Australia & it was gorgeous.However it was only achieved via a big power failure in the area.When I tried it in my home kiln it was a dismal failure- no crystals. Ofcourse I hadn't altered the program to slow cool & I haven't had the courage to try again.(The test didn't run).CaroleCarolenoreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-76301005720193482282018-04-28T15:15:10.631+12:002018-04-28T15:15:10.631+12:00Thank you CristopherJG! :-)Thank you CristopherJG! :-)Peterhttps://www.blogger.com/profile/03078608554226394069noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-49678152348048766522018-04-28T14:39:05.618+12:002018-04-28T14:39:05.618+12:00Amazing!!!Amazing!!!CristopherJGhttps://www.blogger.com/profile/06390945536837301106noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-15625613772940044912017-12-22T13:38:39.685+13:002017-12-22T13:38:39.685+13:00Hi Rick,
Thank you for your comment, it is nice to...Hi Rick,<br />Thank you for your comment, it is nice to hear from you. I do hope you give crystalline glazes a try. The Janet DeBoos Recipe (number 84 in her second book of glazes) is probably one of the easiest ones to try, and you are quite likely to get good crystals forming if you fire to Orton Cone 9 or 10. The crystals will be better still if you slow cool the kiln, holding it at about 1100 Celsius for 2 - 3 hours (or more!) as it is cooling should help the crystals grow larger.<br /><br />Potash Feldspar 35<br />Whiting 12<br />Zinc oxide 24<br />Silica 22<br />China Clay 5<br />+1.5 Nickel oxide<br /><br />Do remember to protect your kiln shelves when firing crystalline glazes, because the glazes are very runny when they are at high temperature! You could try a test on an inside of a small bowl to start with.<br /><br />Good Luck and Merry Christmas!Peterhttps://www.blogger.com/profile/03078608554226394069noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-57873007478111551312017-12-22T02:10:25.052+13:002017-12-22T02:10:25.052+13:00Wow! this is really cool glaze man! really love th...Wow! this is really cool glaze man! really love the cristal shape and the size of it, i have never seen such large cristals in one glaze! deffenitly going to try this glaze..<br /><br />i wish you all the luck developing glazing and making more ceramics!<br /><br />Greetings from the Netherlands and the best of luck!<br /><br />RickAnonymoushttps://www.blogger.com/profile/17265365130602927923noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-71917805496273983862016-08-13T13:50:51.465+12:002016-08-13T13:50:51.465+12:00Hi Kees,
Thank you for your comment, it is good to...Hi Kees,<br />Thank you for your comment, it is good to hear from you. I often use 1 or 2 percent bentonite with crystalline glazes to make them less difficult to apply, and to help them behave better in the glaze bucket! Generally I use little or no other clay. I would love to see your results, and am impressed that you are firing with vegetable oil, I have emailed you directly so that you can reply with photos. <br /><br />Looking forward to seeing your work,<br /><br />PeterPeterhttps://www.blogger.com/profile/03078608554226394069noreply@blogger.comtag:blogger.com,1999:blog-3580639918656230427.post-4530528457417717792016-08-13T11:09:51.748+12:002016-08-13T11:09:51.748+12:00Hello Peter

All a busy whirl here, with one stoneware firing through the night finishing 9.30am today, instead of around 5.30am due to kiln problems. Now firing a crystalline glaze firing with the other electric kiln that is due to finish around midnight. Exhibition deadline is looming very close!! Must go and check the kiln, I'm currently busy putting growth rings into crystals by doing controlled dips in temperature.
