use enough alcohol to comletely cover the charas.
let it evaporate in a pot on the stove for about 20 to 30 minutes. do not let the mixture boil im order not to destroy the thc. it should only bubble and never boil. let the charas soak in alcohol for a 2 to 3 hours and stir regularly before evaporatin it.
thanks for that, ive got it stewing as we speak, ;-) could i leave it over night then cook it up tomorrow? i purchased it from a friend, never had anything like it outside of amsterdam, am planning on a trip myself in the near future to go make some myself, would be an amazing experience.
