Tell your wife to suck it up.
It's now known that NO plastic is safe to use in a microwave and microwaves aren't safe to use either. Especially for something like your meds.
They break apart amino acids making them useless for your body to build proteins from and create carcinogenic particles at a much higher rate than conventional cooking. And to do it 5 or 6 times is huge overkill.
I would lay out a sheet of tinfoil then lay a slightly smaller sheet of parchment paper or a silicon baking sheet if doing a larger batch on top of the foil. Then carefully fold the tinfoil over and do a double seal all around the edges. Maybe wrap again with foil and seal well. With kief it can stick to the foil when it melts so the paper or silicon prevents that.
Then preheat your oven to 250 and heat for 30-45min. Put a cookie sheet on the rack below the foil pack so it doesn't get hit with a blast of too high heat when the element cycles on.
Leave the oven door open a bit when done to allow the foil pack to cool slowly and the evaporated cannabinoids to reabsorb into the pot/kief rather than condense onto the foil if it cools too fast.
With the exhaust fan over the stove going there should be no smells at all. Then you can just simmer the pot/kief in the oil at low temp on the back burner of the stove with the fan on again and marital bliss is maintained.
If you are going to use your oil for baked goods you really shouldn't need to decarb at all. I make cookies or banana bread with kief or pot and it can kick my ass. It decarbs fine as it bakes. If pot has been sitting around at room temp for 6 months it's already decarbed too. I'll eat a raw bud out of a jar I have sitting around and get baked.
