Apparently, it was thin-film cast without heat treatment and I was heat treated at 200 degrees. The difference in heat treatment temperature is large, and it can not be said because "It is good that it is possible to do heat treatment or not, or if it is the same if not heat treatment, why do you do heat treatment?" Here they are. If you do not think about it, just do it. Ethanol is not boiling too high. What the hell are you thinking?
