I made it at TechShop.
These were etched on the Trotec Speedy 300 laser engraver.
Step 1: Supplies Needed
2. A silicon oven mitt
3. Empty wine bottles
4. A 5 gallon bucket
5. A copper scouring pad
6. A glass bottle scoring jig. I used Ephram's Bottle Cutter Kit that I purchased from Amazon. I've also seen a lot of homemade jigs on Instructables as well.
7. A stock pot. Here is the one I used.
8. A small towel
9. Ice cubes
10. Sandpaper. I used 60 grit, 80 grit, 120 grit, 180 grit, and 320 grit.
11. A TechShop membership (for access to a laser engraver with a rotary tool).
