Page "Thermite" Paragraph 37

Apart from magnesium ignition, some amateurs also choose to use sparklers to ignite the thermite mixture.

These reach the necessary temperatures and provide enough time before the burning point reaches the sample.

However, this can be a dangerous method, as the iron sparks, like the magnesium strips, burn at thousands of degrees and can ignite the thermite even though the sparkler itself is not in contact with it.

This is especially dangerous with finely powdered thermite.
