Pete is the professor at University of Nebraska at Lincoln. I thought I'd share his comments on this particular glaze: <br /><br />This glaze performs best at a true cone 6 or a hot cone 6. The key to developing good color is to hold at one temperature on the cool down (in the range of 1800° to 1600°F) for 1 to 3 hours to allow the crystals to develop. The hotter the hold temp, the more deep burgundy red. The cooler the temp, the closer to orange red color. Do not confuse this with a slow cool down. Pick a temp, cool normally until you hit that temp, and then stay there for 1 to 3 hours, after which you'd resume cooling down at a normal rate. Anne M.

So you are correct to suggest stiffening with kaolin or alumina. However, with single dip, there was no running with most of these glazes, Terry Rorisonhttps://www.blogger.com/profile/07140059292969610708noreply@blogger.comtag:blogger.com,1999:blog-2219868802206191151.post-71076279954500692912013-10-01T15:37:35.887-04:002013-10-01T15:37:35.887-04:00Looks like most all these glazes run.

Im particularly curious about the Tomato red, Waterfall Brown 72, 122 Transparent - T12 C/6 Reddish Brown, and 145 - Satin Matt Cone 6 Lt. Green. <br /><br />Also, thank you so much for the effort and time youve dedicated into making these test tiles. They are wonderful!

Make lots of pieces so you get lots of practice so you can learn to control the process. Best of experiences to you.

I need all the help that I can get because we are doing our own Cone 6 high fire glaze. I'm just hoping that my experiment comes out just as good as these. The glazes are beautiful and I look forward to trying some of these recipes out.Anonymoushttps://www.blogger.com/profile/06787733406356485293noreply@blogger.comtag:blogger.com,1999:blog-2219868802206191151.post-60346880969857480552013-01-18T23:24:21.385-05:002013-01-18T23:24:21.385-05:00I have not visited John's page but if he is th...I have not visited John's page but if he is the source of some of these recipes then he is due credit for them.

Basically a similar heating cycle but the cooling was done dthe following way: fast to 1800 then up to 2000 at 50/hr.<br />I have results posted on http://vvargespottery.typepad.com/vvarges_pottery/2011/01/old-iron-red-photos.html<br />Also look for results on Coleman teadust with same schedule.
