Step-by-Step Instructions

1. Prepare the Wood

   • Sand wood slices smooth and ensure they are completely dry.

   • If needed, seal the wood with a thin layer of resin to prevent bubbles.

2. Set Up Your Workspace

   • Work in a well-ventilated area and cover surfaces with plastic.

   • Place silicone molds on a level surface.

3. Mix the Resin

   • Follow manufacturer instructions to mix resin and hardener thoroughly.

   • Divide into smaller cups if using multiple colors.

4. Add Color & Pour

   • Stir pigments into resin until evenly distributed.

   • Pour a thin base layer into the mold, then place the wood slice.

   • Add more resin around and over the wood until fully covered.

5. Remove Bubbles

   • Gently pass a heat gun or torch over the surface to pop air bubbles.

   • Avoid overheating, which can cause curing issues.

6. Cure Completely

   • Cover lightly to protect from dust and let cure for 24–48 hours.

   • Demold carefully once fully hardened.

7. Sand & Polish

   • Sand edges and surfaces until smooth, moving from coarse to fine grit.

   • Use a polishing compound for a glass-like finish.

8. Enjoy or Gift

   • Pair coasters with a stylish holder or box them as a set.

Creative Variations

• Geode Style: Use crushed glass or crystal flakes around the edges.

• Pressed Flowers: Embed dried botanicals for a springtime look.

• Ocean Waves: Create swirling blues and whites with resin art techniques.

• Map Inlays: Add a small map cutout under the resin for a travel theme.

• Metallic Veins: Use gold or copper leaf to highlight wood cracks.

Pro-Tips for Success

• Measure Precisely: Incorrect resin ratios can prevent proper curing.

• Seal Porous Wood: This minimizes bubbles rising from the wood.

• Work in Layers: For thick coasters, pour in thin layers to avoid overheating.

• Test Colors First: Practice color combinations in small batches.
