My husband Michael is the rockman! We have some rough Blue John,
and are seeking some pine resin with which to stabilize it. Does
anyone know where we can get this? Thanks, Louise
Have you thought of using opticon? If it must be tree resin
try looking for Balsam resin or "oil of Balsam" at chemical
suppliers for schools and laboratories. The resin is used for
preparing microscope slides.
