How is black tar heroin made into powder?

Real quick all you do is put a piece of black on a microwave safe plate or glass plate. Next you add 1-2 drops of water (balloon size piece of black ex) and rub the black and water together till the black is liquid form. Now last step you take the plate with the watered black product and stick it in microwave for 15-20 seconds. After it is done it will have turned into a solid brown hardened product. You get a razor blade and scrap it off plate and make your lines! That's All! And now instead of just having one (1) balloon, now you can have a days and a half worth or snortable Black Tar Powder, which works stronger, better, longer, if snorted!.... Enjoy!
