Bisque Fire 5 (High Fire)

Tonight we are in the process of finding out whether our kiln will actually make it up to high fire temperatures. For the first time ever we are attempting to fire to Cone 6.

We started the kiln at 5:40 and followed the standard Bob Protocol. If it was a Cone 06 fire the kiln would have shut off around 4.5hrs after we started it.

It is now 1am, which means it’s been going for just over 6 hours now. The problem is we have no way to see how hot the kiln is right now or whether the heat is actually still climbing or not.

We should be able to see the colour of the inside of the kiln shift to yellow-hot instead of orangey-hot. Seeing as I don’t really know what that should look like I won’t be able to tell :/

So the plans now are to let it go for as long as possible before giving up and going to bed. And I suppose Googling to see if I can get any recommendations on how long this should take.

Anywho: in this firing is the stuff that me and Nic had been throwing at his house. It’s the first time we’ve been using the new PSH 455 clay… which I talk about in this post here.

Out of the Kiln

Glaze Tester – Top Shelf

A: Amaco Teachers Palette – Midnight Blue
D: Duncan – Really Red
DB: Dick Blick – Seafoam
Duncan Clear Glaze
PSH Snowflakes (Cone 6)
PSH Copernican Sky (Cone 6)

I was expecting the first bunch to run a little.. or something since they’re not specifically “Cone 6” glazes. As far as I know only the Duncan concepts are rating to go that high. I’m impressed with how well they stayed where I put them.

Little teacups/shot glasses – Bottom Shelf

Nic’s Mugs with Red Clay Slip – Bottom Shelf

The red slip got much darker than any of the other pieces we’ve used it for, so we know that the kiln fired higher than it has before (Nic’s guessing we got to about Cone 4 maybe)

Mugs – Top Shelf
and I’m either nuts, or these ones are slightly darker in colour the ones on the bottom shelf.. which I’d guess means the top shelf didn’t get as hot

Bowls – Top Shelf
