Quartz Fuming Tubes

Quartz tubing makes the ideal material to hold Fine Silver or 24 Karat Gold for fuming glass. Quartz, with its low COE of 8, is extremely shock resistant and requires an immense amount of heat to melt, thereby giving you secure control of the molten metal during the fuming process when it is placed in a small depression. 11 mm OD, 8 mm ID, 8" (20 cm) long.
To use the Plain Quartz Tubing for fuming, heat up a spot near one end until white hot. Then push a slight depression into the side of the tube with the tip of tweezers. The heating can be accomplished using a beadmaking size torch turned up to its maximum setting if you are using bottled oxygen. If you are using an Oxygen Concentrator/Generator the flame will not likely be hot enough. Purchase the Quartz Tubing with the Depression already in it. Caution: always point the end of any tubing downstream to the flame to prevent the flame from entering the tubing and burning your hand.
