I bought one of those laser-remote-thermometers the other day and today while casting took some interesting measurements:
- Temperature od hotplate set to medium: 600 degrees
- Temperature of brass mold after sitting on hot plate for 20 minutes and removed for measurement: 200 degrees
- Temperature of sprue plate attached to mold (sprue plate is closed while mold is sitting on hot plate. mold removed and sprue plate opened for this measurement): 350 degrees.
