Beach glass is frequently used in jewelry, stained glass, mosaics, and a number of other arts and crafts projects. Nowadays it can be difficult to come by, so it's in increasingly high demand.
So, following are the steps to make your own beach glass:
Make Your Own Sea Glass
1. Fill a tumbler barrel 3/4 full with broken, recycled glass.
2. Add water until you can see it just below the top layer of the glass.
3. Begin with a coarse grit, 60/90 silicon carbide. The amount you use is determined by your tumbler size. This step shapes your glass by rounding the edges.
4. Close the barrel and tumble your rocks for 7-10 days. Check the glass every day to see if it is round to your liking. Once it is, you can move on to phase 2.
5. Wash the glass, barrel, lid, and your hands. Be sure to pour the murky water outdoors, not into your sink.
6. Repeat phase one, using 120/220 grit silicon carbide. Allow the glass to tumble for 7-10 days, or until it has frosted to your liking.
7. For a more refined frosting, repeat the process one more time with 500 grit silicon carbide for 1 to 5 days.
