Abstract
The stone holding downstem end is a modification to a standard downstem end to enable it to hold a porous stone. A standard downstem end is a full circle and only allows the stone to be heated from above. By subtracting material from the receiving end of the downstem we create a new downstem end that is not receptive to a standard bowl anymore, but is instead specially modified to hold a porous stone. With the modification the user can heat the stone from the side rather from just above. This increases the potential for material to be vaporized and less chance for the material to melt through.
