I got a fuge, separated some live. I have a vacuum/pressure vessel to decarb in. I pull a vacuum in the vessel then toss it on the hot plate. First batch came out beautiful, slight pale yellow, clear looking when thinned out. Ran the hot plate at 250c for 3 hours, then 280c for 2 hours because it didn’t appear to fully decarb at 250
Ran another batch today. 280c for 4 hours. Now these are hot plate temps, I have a hard time reading the oil temp. It’s inside a ptfe cup so it’s not reaching those temps.
When I opened it, it had sat and cooled for hours, looked gorgeous, almost clear. Dug into it with my dab tool, came back later and it picked up a purple hue. Dug in some more, got even more purple.
Now I don’t know how to proceed, it appears it’s related to oxidation because it’s only where I’ve dug into the oil.
Should I warm it and dump in my live hte? Will it continue to turn purple?
