The process is super simple and doesn’t require many resources/tools. But keep in mind the safety while sanding glass or any other material.

How to polish glass edges

The simplest method for this is to use wet/dry sandpaper and wet sand the bottle. This way reduces the glass particles in the air during sanding. Make sure you use safety goggles and a respirator to protect your eyes and lungs.

Tools and materials

Polishing the cut glass edges

As mentioned above, sanding glass can be hazardous to your health. In order to avoid these issues, you should do wet sanding so that the particles from the glass are not suspended in the air and contaminate anyone nearby who is breathing them in. Always wear eye protection AND a face respirator when doing this task!

> Start with coarse-grit sandpaper- P60/80 to smooth the edges

In order to get these cuts looking nice and smooth, you’ll want to start with some coarse-grit sandpaper. First, wet the sandpaper before placing it on a flat surface, and using circular motions, begin sanding the edges. Rotate the polished piece to sand it evenly. Wipe the water off the edge and check if the edge is sanded down/smooth enough.

The green bottle had a pretty smooth edge from this method of cutting glass bottles, so it didn’t need much smoothing out.

Then take the wet paper and sand the inner and outer edge. You can use a soft sanding sponge(for wet sanding) for that purpose or material-backed sandpaper for more flexibility, especially for the coarser grits.

> Next, move up the grits until you are happy with the result and smoothness of the glass.

Next I used P100 to continue sanding/polishing the glass. Remember to sand the inner and outer edge of the glass.

Then I used P150, P180, P240, P320, P400, P600, P800, and then finally P1200 and P2000 to finish off polishing the glass.

The final result
