It is important to heat the tube gently and uniformly. Use a medium blue flame and move the test tube around in the flame to heat the entire surface of the tube as evenly as possible. This is important to minimize bumping and cracking.

Explanation:
A boiling tube is a large tube made of glass, which is used in laboratory to strongly heat substances. This larger size allows substances to boil freely inside a boiling tube. Boiling tubes can also be used as a replacement for test tubes specially when a larger volume is desired.
