Mik Kyklo Posted February 24, 2021 Report Share Posted February 24, 2021 Hello, I would like to know if there is any problem, cooking Linseed oil/Colophony type varnishes in corcked erlenmeyer flask. I cook till ~280 C and I am using a simple electric cooking plate (so tempereature let's say that has not so much stability -- it is not like pro magnetic/heat plates that are used in labs). (By the way how can I check temperature in a closed flask? I have an infrared thermometer.) Is it safe or am I making a kind of "bomb" by heating oil/resin in the absence of oxygen?
