Colored Glass


This is a nice batch of crushed Glass. The pieces range in size from 1/2″ to 1 3/4″ and vary in color as seen in the photo. Glass will polish best by not mixing it with other types of stone and using an additional pre polish step of 1000 grit Aluminum Oxide. In a rotary tumbler, use plastic pellets to cushion them in the last three finish steps. If you are using a vibrating tumbler, use ceramic media with them in the last three steps for best results.

MOHS hardness scale of  5.5

  • Please note this material may have sharp edges.


These are the steps we used to tumble the glass in our Lortone QT12 Tumbler:
1. 120/220 Silicon Carbide for 5 days for the first grind. We checked for shape at 4 days and suggest running another day if needed to get the desired shape.
2. 500 Aluminum Oxide for 4 days. We used small ceramic media in the last 3 steps.
3. 1000 Aluminum Oxide for 3 days.
4. Aluminum Oxide Polish for 3 days.
