I bought a cofee grinder from wall mart for 15 that works real well. I grind about a quarter into almost dust and seperate a good bit of kief that i press into hash by putting it into a pice of plastic bag to hold all of it. Then i form it into a kief ball inside the pice of plastic. Then i stretch rubber bands as tightly as i can around it. After you get maby 3 rubber bands tightly around it i open it up and adjust the ball which is firm but will crumble. I adjust the plastic to firmly fit the hash ball and then repeat the tight stretching of rubber bands around the ball. I make it as tight as i can and bounce it and play around with it for about 18 hours(but it doubt it takes that long) then i open it up and its a hard rock. It looks the same color as the kief started but you can make it a dark green but black looking color by adding slight moisture before you apply the rubber bands and it will also occur if you find a way to heat it inside the rubber band ball. I have found that steaming it(because i work at a place that uses steamers) heat from being in your pocket or from a heat source like a car air conditioning on heat or somthing simmilar will also give it that dark color rock most simmilar to black lava stone. The rest of the bud i smoke in my one hit.
