Hello everyone, got a question about the ratios here. swim has done several lazymans stb extractions in the past with mhrb with no problems. recently they tried acacia confusa using the same tek and it worked just great. always got 6-12g yields. the tek used was 3L water mixed with 200-250g lye. and after the solution cooled, 1 lb root was added and a few days later did pulls with naphtha. anyway the last 2 attempts yielded very low 3-6g. it also liquified after it was filtered, no crystals. the only thing they could imagine they did different was not measure the lye and added to much maybe? is this lye lock?. anyone know if the quality or chemicals changed in colemans camp fuel in the last couple years? same source, same tek. another question swim had was if they used the same tek would it be too much lye if they only used 220g root bark instead of 456g or would they have to change anything? any feedback would be appreciated.
