A recent thread included a link to the web site of Hansruedi
That site contained a slide show demonstrating mokume and showed
wrapping the mokume in stainless steel tool wrap and THEN clamping
the wrapped mokume in the clamping plates. This differs from the
technique I was aware of which is to clamp the mokume and then
wrapping the ENTIRE assembly in tool wrap. Which works best? Wrapping
only the mokume certainly uses a lot less tool wrap and (if you wrap
it tightly enough), should eliminate the need for charcoal.
