Hashish mixed with oil (rosin)
Look at the bubbles on the surface. This is sometimes seen in hashish, hinting at the fact it may be mixed with another resin, not related to the hashish production.
This could be either good or bad, depending on the mixed resin.
Bad: Synthetically produced cannabinoids/distillate, with poor production.
Good: Properly produced resin, such as rosin, without any solvents or contamination factors.
@Greenconstruction If you mix distillate into your hashish, you will get the same bubbly surface on your hash as this picture.
The color doesnt have to be as dark. That is just because of the type of hash being dark (distillate is usually transparent).
