A friend has an opportunity to buy a used 72" Denver clamshell kiln. In reading past threads here, I saw several unfavorable comments about them (i.e.sagging blanket).. Has anyone had good experiences with them? And I realize they are out of business, which could be problematic if the kiln has issues.
thx.

kind of telling that you can't find any positive testimony on denver kilns
I remember using a couple of Denver front loading Annealers in school settings, they must have been made in the late seventies. The original controls were funnily made, pre-electronic devices.
The Denver 40 pound electric pot furnace was also a decent design for its time
Seems they were heading downhill by the time the warm glass movement got going. The only kiln I didn't make for myself was a large denver top loading one, and it was very poorly made. I had to redesign it almost as soon as I got it, as the wall the hinge was attached to couldn't take the weight of the door, and when I complained, they sent a kit to fix it that wasn't up to the job either
I wound up selling the thing, and haven't missed it one bit

We decided not to get it, but thanks for the info and sorry you went through all that with your kiln!

I have one, it's been good for last 10 years, only thing I replaced was a thermocouple last year. I use it almost every day.
