I REMEMBER TRYING TO DEVELOP A PERFECT BOWL WHICH ALLOWED COMPLETE CONSUMMATION OF THE MARIJUANA OR HASH WHICH WAS BEING SMOKED USING MY PRECIOUS METAL CASTING FACTORY AS A LABORATORY.
Centrifugal casting
I FOUND THAT SOLID STERLING SILVER BOWLS WERE JUST FINE AND PURE ALSO.
THIS WAS THE PIPE USED AND THE STERLING SILVER BOWL WHICH RESULTED.
HOWEVER, STICKY RESIDUES WOULD ACCUMULATE ON THE INSIDE OF THE HEAVY, COOL SILVER BOWL AND HASH OR GRASS WOULD BE STUCK THERE INSTEAD OF BEING SMOKED. IT WAS HARD TO CLEAN.
I MADE A HALF OF A CIGARETTE PAPER INTO A CONE AND NIPPED THE POINT OFF.
THE PAPER DOES NOT BURN AND IT ABSORBS OILY RESIDUES AND AS IT INSULATES THE BURNING CANNABIS FROM THE COLD BOWL THERE IS NO BUILDUP OF STICKY RESIDUES.
THE PIPE STEM ALSO STAYS COOLER.
