Add 100g lye (been seeing a lot of talk lately that 10-15g may be all that's needed. Check your pH. It should be over 12) to 750ml water, 25g/15 minutes. Stir until dissolved and rest.
Don't allow lye to stick to the sides and don't add too quickly or it will boil and potentially crack your glass. Once added, rest for 4-6hrs until it looks clear.
Add your root bark slowly, stirring out the clumps before adding more. Stir for three 3 every 3 hours for 4-8 cycles. Soup should be deep purple to black and consistent.
Add 150ml and stir 3 minutes. Rest 2-4 hours (if emulsion layer forms, wait until it falls). Stir and rest 4-6 times. Use PTFE paper to protect the lid from being exposed to the heptane, as it will dissolve the underside of the lid into your soup.
Mix 50ml water and 10g wash powder in pint jar, then carefully pipette the solvent layer from the root base into the wash solution and shake the hell out of it with PTFE protecting the lid.
Pipette the washed layer onto the Pyrex dish, cover with lid and cling wrap the whole thing to protect it from excess moisture in the freezer. Rest 12-24 hours. Pour off heptane back into root base for a second extraction.
Place the dish upside down at an angle over paper towels with a fan blowing under to for 2-6 hours. All that's left is to razor it and repeat for second extraction.
