just smoke mad herb out of your fine glass piece, @ least an oz., preferably a quarter pound or more, but anywhere as little as a quarter ounce, and then just clean it out with 91% OR HIGHER isopropyl alcohol, shake it up good in there and make sure to get it ALL out, pour the now-black thc-laden liquid onto a nice ceramic or glass plate, leave it alone for a while until all the rubbing alcohol evaporates (anywhere from one hour to overnight, depending on environmental factors), dry product and smoke! You are now, once ALL the alcohol has evaporated, left with a very potent and pure form of HASH.

peace,
