To remove nail glue from glass, you can start by soaking the affected area in warm, soapy water to help loosen the glue. Then, use a plastic scraper or a credit card to gently scrape off as much of the glue as possible. If there is still residue left, you can try using acetone or nail polish remover on a cotton ball to dab at the remaining glue until it comes off. Be sure to wash the glass thoroughly with soap and water afterwards to remove any remaining residue. **

Then, use the pointed end of the iron nail to carefully scratch the glass, applying even pressure to create the design. You can also use a template or stencil to guide your engraving. It's important to work slowly and carefully to avoid shattering the glass. **
