What are good heat-resistant surfaces to use under a charcoal block
or annealing pan? Rio sells 12-inch by 12-inch Silquar(TM)
High-Heat Blocks for $21.50 U.S., rated to a maximum temperature
of 2000 degrees F (1093 C) -- is that a good choice? What type of
fire extinguisher is best to keep nearby when using butane?
The block from Rio you sited is similar to what I use, when
concentrating on soldering it is good to have the extra protection a
larger surface to work on.
On the fire extinguisher, I would use a C or one of the other clean
ones as you will be in the room with it. I have put out fires with
the ABC types and what a mess. On a car or trailer not that big a
deal and on liquids it is my preference, but should you ever have to
use it in the house, that white powder goes every where.
