[Gasification] Junked Hot Water Heater Tanks.

I've found most of them to have sprayed porcelain on the interiors.

Dear Mark & List,


Since the early 80's junked hot water heaters have found a soft spot in my
heart. BUT, the one I am using now has somekind of coating on the inside.
So ventilation, ventilation, ventilation when welding or cutting them!!

Recycling at it's best!
