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).
Step 2: Removing the labels from the wine bottles
1. Cut the plastic bit off of the neck of the bottle.
2. Soak the bottles in a 5 gallon bucket filled with hot tap water. Let it soak for at least 20 minutes, the longer it soaks the easier it comes off.
3. Using the copper scouring pad, scrub the labels off. The copper is too soft to scratch the glass. Make sure to get the adhesive off as well as the label.
