Has anyone tried this laser thermometer? You can't use it on a reflective surface like aluminum.. I was thinking since I use a metal crucible, I could take the temp of the crucible, and be close enough, or make an adjustment..

As long as you can set the emissivity (which for aluminum melt is between 12-15%), you should get a number close enough to work with. Always good to have a contact thermometer to use once in a while as a sanity check.
