Stephen Posted November 26, 2016 Report Share Posted November 26, 2016 I no longer have access to small test kiln and running round of test tiles in 7 cf Skutt 1027 digital controller. I put in shelves and put my tiles on middle shelf. cone 5 with 20 minute hold. I normally would plan to add test tile to next load but this is first test of all newly mixed glazes so need to run test before first load. I'm wondering will my results be different than normal kiln load? Link to comment Share on other sites More sharing options...
glazenerd Posted November 26, 2016 Report Share Posted November 26, 2016 Depends if you are using a cooling segment, or controlled ramp holds to produce color effect. If it is a straight forward firing to peak, then cool: very little. Your small test kiln cools much faster; which would cause very slight to no changes.

Mark C. Posted November 26, 2016 Report Share Posted November 26, 2016 Empty kilns can fire quicker and cool quicker -this can make your glazes look different than a slow full load. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted November 26, 2016 Report Share Posted November 26, 2016 Too bad you couldn't fill the kiln with pots. It will be an inaccurate load for test tiles. Marcia Link to comment Share on other sites More sharing options...
Stephen Posted November 26, 2016 Author Report Share Posted November 26, 2016 thanks guys, ya know I'm stting up solo but have used this glaze lineup for 3 years and mainly wanted to make sure on thickness as I am using different water source. I make serveral and buy the rest from the same source. Putting together a booth from scratch and the serveral hundred pieces I am glazing are really all needed and I could bring my self to isolate a potentially sacraficial load. It is a controller controled ramp up and down to I think 1200, wouldn't that help? Link to comment Share on other sites More sharing options...
Mark C. Posted November 26, 2016 Report Share Posted November 26, 2016 Instead just buy a plastic 100ML vile and weigh your liquid glaze-when you have it right (water to material) write it down and then you can mix to this number every time. No more firing to test thickness. Hope this is clear. You should be able to scratch the thickness as well instead of firing tests. Link to comment Share on other sites More sharing options...
neilestrick Posted November 26, 2016 Report Share Posted November 26, 2016 If you normally do a controlled cooling in your firings, then do the same with your test tiles and your test will be accurate. Without a controlled cool, the kiln will cool much faster and your results may be different than in a full kiln. Link to comment Share on other sites More sharing options...
Stephen Posted November 27, 2016 Author Report Share Posted November 27, 2016 Thanks for all the great advice everyone, firing finishing up now so will see whatever it is in the morning and make a few adjustments and start a load tomorrow.

High Bridge Pottery Posted November 27, 2016 Report Share Posted November 27, 2016 If I ever did not have a full load I would refire some pots that were below par (never going to be sold) to fill up the empty space. Link to comment Share on other sites More sharing options...
