Re: Glass bowls and screens?
I saw a few videos where the people went to a crafts store and got glass "rocks/marbles/stones" (like in a flower vase or fish tank) and use it as a screen. The only issue was ask falling onto the tobacco. Just make sure to heat up the rocks/stones before hand to burn off any impurities.
