Just need to know if I need to wrap it, with what, and how.
binding wire is ok, I would not use duct tape personally because it
burns, and combustion of plastics and vinyls require a good
cartridge type respirator…another more permanent and efficient
method is to embed it in a simple frame with investment or plaster
poured round the block. it absorbs more thermal shock and forces the
block into submission- or not cracking so readily ! anything from a
recyclable double walled cardboard box to a wood frame can be used
and freezer paper makes an adequate temporary base to pour it on (
shiny/plasticized side to the pour…) if selecting a wood frame sans
Another tip is to buy the hard grade charcoal block (Contenti Co. in
Rhode Island is one source of varying sizes of hard grade block) as
they inherently last longer due to the temperature,kiln conditions
and woods that are chosen for production of that grade of charcoal.
