Today I'm retrieving old potassium carbonate and distilling alcohol from when I made absolute alcohol a few weeks ago. This helps cut down on costs and reuses a lot, as a lot of material is used in this process. You can see in the picture what the goopy potassium carbonate looks like when it's dried. Because it tends to spit a lot, getting everything around it covered with potassium carbonate, I use a cylinder made out of flashing for roofs as a shield to help with this. Stirring when it's closer to being completely dry helps as well, as it otherwise is very difficult to scrape out of the pyrex dish. The distillation is just a normal distillation in a water bath. Usually the alcohol ends up being at around 90%.
I'm also calcining some caraway for both Salt and Salt of Sulphur. Every time I calcine Salt of Sulphur it always takes more heat and longer periods of time and regular Salt (of Salt). Maybe because of the increased amount of organic compounds in the Salt of Sulphur.
