Filling and Heating Without Bumping
Fill no more than a third of the tube when it is to be heated. Hold it in a wooden holder at a slant, point the mouth away from everyone, and warm the liquid near its surface while shaking gently so it does not shoot out. Borosilicate glass copes with the change in temperature, but let the tube cool before washing it.
