How to make a cannabis tincture - The Cannigma

Take your dried cannabis and grind it. A hand grinder is best, but you can also use a food processor or coffee grinder. Once you've finely ground the cannabis, place it on a cookie sheet and bake at 240°F (115°C) for 20-30 minutes. This decarboxylates the cannabis, a necessary chemical reaction in the production of edibles.

"High Grade" | & Metal Extraction Forum

Gold ore from the ground that produces an ounce of gold from one tonne is considered very high grade ore. A tonne of ore is about a square yard of crushed or milled material. I consider gold scrap in relation to work needed to recover the gold. I consider IC chips as the true high grade electronic scrap.
