PS One more thing - I see some articles about building pizza ovens that talk about using portand where you have to wait about 3 weeks before first heat. As it is now past mid-November in Vermont, this just isn't an option. I need something that will be ready in 2 or three days if possible, if just to get me through winter, and then in spring I can do something better.
12 oz tube of high temp caulk as opposed to heavy machinery digging up clay from open pit mines that take centuries to revert back to their original look. I think I'll go with the 12 oz tube of caulk.
I don't want to screw this up so I thought I'd ask first.
What should I mix to together that is going to do a good job sealing the bottom of the barrel, as well as mechanically holding it in place but at the same time not concreting it in place for all time?
