When enhancing laser engraved coasters, several finishing techniques can elevate their aesthetic appeal and functionality:

• Sealing: Apply a clear sealant or wood finish to protect the surface and bring out the natural colors of the material. This helps prevent moisture absorption and enhances durability.
• Staining: Use wood stains before engraving to add color depth and richness to the coasters. This technique allows the engraving to stand out more distinctly against a colored background.
• Burnishing: Gently rub the engraved areas with a soft cloth or fine sandpaper to smooth out any rough edges and enhance contrast between the engraved and unengraved areas.
• Polishing: Use a polishing compound or beeswax to give the surface a glossy finish, which not only improves appearance but also offers a protective barrier.
• Edge Finishing: Consider rounding or beveling the edges for a smoother feel and to minimize splinters, ensuring a more professional and polished final product.
• Customization: Add additional elements like paints or metallic foils to emphasize certain parts of the design, making the coasters more visually appealing.
