Coelho! Good to hear from you!

I just took 12 drops, so we will see soon if there is anything in this stuff. I took your suggestion and counted drops into a 1/4 teaspoon measuring spoon. The spoon is also labeled as 1.25 ml. About 25 drops went into the spoon, so about 20 drops per ml. So it looks like I was probably taking very small doses. Hopefully this dose will work!

If it does work, then I think next time I will skip the decarboxylization and rely on the longer cook time. I always feel like the decarboxylization step in the oven is one where you could accidenally vape out all your weed and ruin the whole thing. If that step can be avoided, I would like to do that.

I also want to avoid any problems with oxidizing. The weed stayed pretty much submerged in the glycerin, so I wonder if that shields it some from oxygen. Also, I covered the cup with foil, so even if there was some oixidizing, maybe there was less air mixing to replenish the oxygen. I don't know if that would help or not.

Also, I was thinking about this. I have various sized "mason jars" with lids that seal with a rubber gasket and a clamp. They are designed to be used for canning fruit, so they can take some high temperatures. I have a small one that might be useful for some of these cooking experiments. I'm thinking I could put the mixture in the jar, put the jar in the roaster without the lid clamped shut, let the jar and air inside come to temperature, then clamp it shut. I don't want to create a bomb, so I don't want something where a lot of pressure would build up inside. But it seems like if the air is already up to temperature and there is not a lot of water moisture, then there should not be a pressure build up. Glycerine does not evaporate at low temps like 200 F, does it?

Actually, now that I think of it, I have one small mason jar that does not close with a clamp. The gasket is built into the flat metal top. The top rests over the lip of the jar, and you can seal it down with a threaded ring that you tighen down over the top. I wonder if I could just rest the lid on top of the jar with the ring in place, but not tight. Then if pressure needed to be released, the lid would have room to let some vapor escape, but if pressure dropped inside the jar, no air would mix back in because the lid would seal itself against the vacuum.

Wow. I fell like I am rambling a bit now. I think I am starting to get high. Maybe it is working. I'm loggin off now and going for a swim. Thanks for the feedback!
