Glass - Engraving of glass floor

As part of a small series of tests, we gave whiskey glasses a personal logo that is perceived when drinking.
The engraving was created mirror-inverted.

The art of engraving glass lies in the dosage of energy. Too much energy quickly leads to sharp edges on the edge of the engraved area. This can cause injury during use or cleaning.

The trick to a clean and not-so-sharp surface is to use a wet kitchen towel to absorb the energy that hits it.
