Then I'm not as savvy as I should be.
I saw a guy in Afghanistan(?) on a video who started with a big ball of what I assumed was hash. He worked it in his hand and over a propane flame until he had a thin, plate size piece that he sandwiched before sealing in plastic.
I had also assumed there was a mild heating process and compression to turn their (extraction method) kief into the plate. The non-bubble hash I've had has either been green hash or a piece broken off a block. I understand compressed kief being green. Not the block hash being brown. Also balls of hash that are kneadable. Scissor hash, finger hash, bubble hash, dry sift, beard hash I understand, too.
