Begin by pre-heating your oven to 350 degrees.
Have your marbles nearby in a container or bowl, or in a yellow Augustana frisbee in my case.
With the marble pack I purchased, some of them had a matte paint covering (shown on the top). DO NOT USE THESE, OR ANY MARBLES WITH COATING ON THEM! The paint or gloss will burn in the oven.
Lay a sheet of foil over the tray and place each gem in a single layer along the tray. Try to have the marbles avoid touching the sides of the tray or each other (to prevent melting).
Set a timer for 20 minutes.
