Can tufa be used as a soldering block? as you would
charcoal? Is it cheaper? Any advantages? Just wondering!
Gini in already hot Fla.
You probably could use it. maybe it’s cheaper. Dunno. But it
would not offer the nice reducing atmostphere and heat reflecting
qualities of charcoal. And, it’s a bit coarser grained than
charcoal. And I’d guess that a direct flame would start to melt
the stuff… If you’re gonna go that route, then save the cash
or trouble of getting tufa, and go get some decent fire brick.
Cheaper than tufa, and it comes (if you get the right kind) with
a fairly smooth surface… At least that’s my thought on the
