Make sure your engraving surface is relatively stable, horizontal and won't roll. The cream is relatively viscous but will drip during the time it's left to engrave, so be mindful of the areas it may drip to. For the wine glasses pictured, bunched up paper towels and newspaper served to prevent motion.
Make sure all PPE is in place before opening the cream. Chemical burns are no joke! Any skin contact should be put under running water. Using the popsicle sticks, apply a consistent coat of cream to all the exposed areas of glass. A small amount of cream goes a long way, as long as every area is covered. Allow the engraving to settle for ten minutes, then dunk the surface into a basin of water. Using gloved hands, remove as much white residue as possible, then use running water to remove the rest of the cream. The engraving will look very faint, this is normal.
