"Dripping in" of alu foil, see

(LaBTop: "Re: Making Clear", Methods Discourse), so it works as expected. Now try alu powder added with a powder funnel.
Should bring your alu consumption back to very acceptable minimal quantities.
You see, it's advantageous to be drunk on a regular basis.

Btw, if those 1 on 15 and 1 on 10 ratios of ketone to solvents could be brought back to normal quantities, then you have your "Most wanted" Hive procedure! Good work!
Btw2: In summer, put your bucket and the whole stirrer setup in an open freezer, the cold air will stay inside if you use only a PC exhaust fan to blow cold air to the bottom of the bucket. Cold air is much denser than warm air.
If you can buy a small camping freezer, fill the bottom with car-antifreeze up till 10-20 cm, use an overhead stirrer, and put your bucket in there, the freezer will work much better that way, only choose your quantity of antifreeze carefully, if too much, the freezer will have to work too hard, overheats it's compressor and shuts down or simply burns out when it has no overheating breaker device.
Bin there, done that, works FINE! Slowly increment the freezers knob settings to give the compressor time to adjust to the antifreeze temp. They are meant to cool AIR, you know, but you can fool them this way. Clever ones precool their antifreeze!
Look for a freezer which doesn't have it's coils fit all the way up along the walls, then the coils which are above the antifreeze level will get HOT! Older types cool only the bottom. LT/
