Well..... not too sure by what you meant by 'pure glass' but this shtuff is rocks and sometimes have a slight yellow tent to the bigger rocks.. and it smashes up to a VERY fine WHITE WHITE WHITE powder.......
i told him to get a spoon, put some saline in it, or Ill tell him to use bottled spring water if he cant get saline, and to put the line in the liquid, shake a bit, possibly stir with a needle (not the syringe needle) and then take a piece of cotton, like a little piece, put it in the spoon, then press the open edge of the needle to the cotton and suck it up that way, then get al the bubbles out by flicking the side, then find big vien that is visiable, stick in slow, pull back to see red inside tube, then inject that mixture......
should this be right?
