Heating a Tube in the Holder
Push the slide back with your thumb, place the jaws around the tube near its mouth and let the slide return so the jaws close on the glass. Hold the tube at an angle in the flame with the open end pointing away from everyone, and move it gently so the contents warm evenly instead of boiling up suddenly. Wood is a poor conductor of heat, unlike the steel wire frame, which is why the handle is made of it.
