akin4843 Posted December 4, 2013 Report Share Posted December 4, 2013 I am using a Skutt Manual Kiln (Lo/Med/High Knobs) and this is my second glaze firing on the kiln. The first batch came out where I'm pretty sure I over fired because they all came out brown. Well this time I stopped the kiln (sitter is broken) earlier to see what happens and I noticed that the color of some pots are "ok" while others are still too dark. You can see below and example. In the pic those two bowls are the same glaze color (croc blue/coyote) but the one on the right is just way to dark. I forgot to note what part of the kiln the pots were stationed so I can't rule out uneven elements....although the elements are new. Also, this was done at cone 6. I was wondering if I fired at cone 5 would I get better results...Not sure what to do here as I have little knowledge of kilns and this old manual kiln was all I can afford at the moment..Any ideas/suggestions? Thanks in advance! Link to comment Share on other sites More sharing options...
bciskepottery Posted December 4, 2013 Report Share Posted December 4, 2013 Looks to be more of a glaze thickness issue . . . the one that looks too dark probably had too thin of a glaze application; the nice blue one had a better thickness.

mregecko Posted December 4, 2013 Report Share Posted December 4, 2013 I agree it's a glaze thickness issue. This appears to be a pretty typical floating blue glaze (or blue rutile, or whatever you want to call it). They pretty much always go on brown where their application is thin. And, in my experience, cone six floating blues are very resilient to changes in temperature up or down a cone. They will still come out blue, just with a different visual texture.

neilestrick Posted December 4, 2013 Report Share Posted December 4, 2013 Agreed, glaze should be thicker to get the blue. Link to comment Share on other sites More sharing options...
Roberta12 Posted December 4, 2013 Report Share Posted December 4, 2013 I agree, because I have done that myself. Too thin of an application, and bingo! It's brown. Link to comment Share on other sites More sharing options...
akin4843 Posted December 4, 2013 Author Report Share Posted December 4, 2013 Oh thanks guys......I was so worried it was an issue w/ the temp in my kiln. When I mixed my glaze I think I ended up thinning it out too much. Is there a way to thicken it back up again, or should I add more dry powder to the mix?

Chris Campbell Posted December 4, 2013 Report Share Posted December 4, 2013 One way to get water out of a glaze is to hang a cloth on the rim with one edge just touching the glaze ... The water will wick up the towel without disturbing your glaze. This works well with slips too. Link to comment Share on other sites More sharing options...

Pam S Posted December 5, 2013 Report Share Posted December 5, 2013 Coyote glazes are great when applied properly. When they suggest thick application, they MEAN thick. Link to comment Share on other sites More sharing options...

Bob Coyle Posted December 6, 2013 Report Share Posted December 6, 2013 Wow Chris... I'll bet this will work to get the last standing water out of a bucket of raw clay I dug up and slacked without pouring off any of the fines. Thanks! Link to comment Share on other sites More sharing options...
