A few weeks ago, somebody posted casting techniques that
mentioned a medium called ’ Tufa’. The process sounded much like
Cuttle Fish casting however, the material sounds as though it
might be more durable than cuttle fish. I would really like to
know if this material is available on the open market and if it
is as good as it sounds. Thanks in anticipation.
