To enhance the appearance of your engraved slate coasters after the engraving process, consider the following steps:

• Cleaning: Ensure that the coasters are free from dust and debris. Wipe them gently with a damp cloth, then dry thoroughly.
• Sealing: Apply a stone sealant to protect both the slate and the engraving. This step not only preserves the clarity of the engraving but also enhances the color and sheen of the slate.
• Polishing: Use a slate-safe polish or a natural stone polish to give the surface a subtle shine. Apply with a soft cloth and buff gently.
• Enhancing Engravings: If you want to make the engravings stand out more, consider using a food-safe filler, like epoxy or colored resin, to fill in the engraved areas. This can create a striking contrast against the slate.
• Display: Finally, showcase your coasters on an attractive holder or display them on your coffee table. This can transform them from functional items to decorative pieces.

With these simple steps, your engraved slate coasters can look fabulous and last for years.
