Basification with Lime:
This step utilizes the alkalinity of the lime to convert the polar DMT-acetate in the vinegar-water (a polar solvent) into non-polar DMT freebase which is soluble in limonene/xylene (non-polar solvents) and not soluble in water. Since lime can raise the pH to 12-12.5 the pH of the "mush" should be close to that though once again pH testing shouldn't be necessary.
MAKE SURE YOUR LIME IS Calcium Hydroxide OR ELSE THE TEK WILL NOT WORK!
Step 1: Add to the mix at least 3g of lime for every 4g of MHRB used. (IE: 150g lime for 200g MHRB.) Don't be fussy though, more lime will not hurt.
For those of you without scales: 1 cup of lime is 130-150g.
Step 2: Stir it very thoroughly until all the pure white lime is mixed and there is no more red. The mix tends to form a "dark top" when you stop mixing - that is fine. It is completely normal.
Step 3: Create the right consistency.
There are 3 different consistencies that you can shoot for with a lime-tek. Each one will require slightly different methods of mixing and separating the solvent, but none of them are obviously superior so I'll just briefly talk about them.
Once you have achieved your desired consistency, move on the the Pulling with Non-Polar Solvent
