SWIM is doing the Q21Q21 tek, without lye. She is extracting a kilo, though, and cake-mixing bowls are too small!
Is it OK to use a plastic, 5 gallon paint bucket? Just for mixing - not for precip, of course.

I wouldn't use one. Purity is Important.

Just do it in little bits.

Doing a whole kilo at once is very risky. If you spill the vessel you could be saying good bye to 10+ grams of spice. Who needs 10g's of spice all at once anyway?

Try and find some glass or hdpe containers.

Do it in 500g lots keeping the rest of the plant matter in the freezer, and use HDPE bottles check out milk, distilled water etc bottles and look for the markings http://en.wikipedia.org/...U%2B2674_DejaVu_Sans.svg

Wow 1kg bark, do smaller extractions and use them HDPE2 milk jugs.

...but yeah....the white 5-gallon bucket with the lids are really tough to get off...those are HDPE.

Do know though, that hand mixing a 1.5 kilo mud mix of mhrb/lime is going to require some tough stirring and a strong stirrer (like stainless steel)

He may find that it's impractical to physically work with such an amount.

I wouldn't do more than 500g with a manual hand mixing lime tek.

Thank you all so very much.

And, by no means does SWIM need 10g of spice for herself. SWIM just likes information.
It might be illegal in her country, and she doesn't take any chances with stuff like that.
