The pot the burner was on was not a brew pot. It is a solid stainless steel, very heavy, very expensive, pot that we cook large amounts of soup or lamb-curry in. It was far better and much more stable than the Outdoor aluminum BBQ table I have. It is also very impervious to heat. It's not ideal, but it worked perfectly. I also had a full-size fire extinguisher at hand ready if need be.. just in case.
I wish I had a bigger house with a backyard and an off-house man cave with a workshop. THen I could do it right. ... one day.
