Protoplast plastics

Irecently tried some of the new protoplast plastic available
from aquaplast and got some really great results. My problem is
now i want to cast some of these results and can’t get any
burnout such as temp, time or ash. also toxic gases
from burning? so anyone out there had any experience with this
stuff in a burnout? I will be trying it out anyway,but would
appreciate any existing knowledge. thanks orchid Frank,
