In Aleks Foolproof method, step 18 recommends using %25 of the total glycerine and mix with 10% phosphoric acid. Can you use other types of acids for this? how about citric or sulfuric? i have seen these mentioned when doing the bubble wash? Should you use the same acid when doing the bubble wash as what was used in step 18?
************ step 18 *************** 18. For easier washing: Drain off the glycerine. Measure off 25% of the total glycerine (including previously drained glycerine if you followed step 15) and mix with 10 milliliters of 10% phosphoric acid (H3PO4) for each litre of oil/fat processed. The mixing can be done with a wooden spoon in a plastic container. Pour the acidified glycerine back into the reactor and stir for 20 minutes, unheated. Allow to settle for at least six hours and then drain the glycerine fraction completely. ------------------------ Yahoo!
