Fabric burn test

I'm just working on printing on different fabrics, and realised I've no idea what type of fabrics I have in my vast collection. I've just found this online and thought it might be useful.

How to determine fabric content by using the burn test.


Snip a piece of fabric equivalent to 1" square. Using a butane lighter and holding the fabric with a pair of tweezers ignite the fabric over a non-flammable surface in a well ventilated area. Examine the quality and color of the flame, the odor produced, and the  quality of the resulting ash or cinder.  Use this table to help determine your fabric's content.
