what is a spark tester
Spark Testing. Spark Testing is used to identify different types of steel. Carvers are always unearthing tools at flea markets or reviving tools passed down through generations. Sometimes it is just a tool that has been over sharpened and it was your favorite. Whatever the case, these are tools that you would like to be able to rework. 2. Spark Test for Metal Identification. A spark test is a simple but reliable way to identify metals. A handheld grinder is all that is needed to produce the sparks. The different colors of the sparks can help identify the type of metal. To do a spark test, simply hold the grinder against the metal and give it a short burst of sparks.
