Hash Tips - by Robert C. Clarke
What color is it after a piece is pressed in your hand? Higher quality resin powders turn darker much faster than lower-quality powders.
How pliable is the hash? Hashish should be hard at room temperature and become pliable after hand warming. Hold the piece in your hand for a few minutes. The higher the percentage of resin, the faster it will soften enough to be kneaded. Really hard hash can be potent, but it is almost certainly far older and harsher.
How fast does it burn? The rate at which a piece burns is determined by its density, which is determined by the ratio of resin to plant matter. Fluffy or spongy hash is predominantly plant matter. Denser, purer hashish burns slowly and completely.
What does the hashish taste like? If a small piece of high-quality hash is put in the mouth and chewed, it often produces a peppery sensation. If hashish tastes like vegetable matter or contains gritty/sandy dirt, it is contaminated.
How does the smoke smell and taste? When pure cannabis resin burns it produces a pungent, spicy aroma, like fine quality incense. Good hashish always smells rich and sweet.
What color is the smoke? When high-quality hashish burns it gives off milky-white to slightly blue-gray smoke. If the embers give off a brown smoke it is a sign of contaminants. If the smoke from the embers is very dark brown or black, the hash is highly adulterated with substances which might be hazardous to your health, and the hash is likely of exceptionally low quality.
