Hmm...Partial success. Looks like it needs to be 1650 C.

I totally did not realize I was increasing 110 C each time. 😕
archeaids.bsky.social
Me, "I'll try 320 C."

Nope...

"Okay, 430 C."

No...

"Alright, 540 C should do it. That is 1004 F."

TBD

It has all to do with oxygen. With this kiln there is no way to do a reduced or neutral firing. I'm running an experiment this afternoon that should give me more options.

I see the Lawnus impetitis (lawn imp) made the grass grow again. I wish Patch could catch the little bastard.

I have the kiln in cool down mode now. If like yesterday, the cool down will take 7 hours before I can bring it in the house & 9 hours before I can open it at a safe to touch temp.

Me: Frozen pizza or pot pie?

Ann: I'm tempted to order a pizza from Milan's & pick it up.

I pull out a $20 & hand to her.

Ann: What are you saying?

Next time I have to turn the cart sideways so I can see the frigging temperature instead of constantly getting up to check if it has reaches the target temperature yet. 🤨
