7. Terrazzo Coasters with Jesmonite
What This Idea Means
Jesmonite or eco-resin terrazzo coasters bring a bold, Mediterranean stone aesthetic to tabletop surfaces. Creators combine liquid acrylic resin with mineral powders, adding crushed colorful chips to achieve iconic mosaic-style composite stone coasters.
How to Make It
- Prepare colorful terrazzo chips ahead of time by spreading thin layers of colored Jesmonite mix onto plastic sheets, letting them harden, and crushing them into small flakes.
- Mix the primary Jesmonite liquid and base powder according to the exact product weight ratios in a mixing cup.
- Stir in your prepared colored terrazzo chips until distributed evenly.
- Pour the liquid mixture into silicone coaster molds, tapping the sides firmly to release trapped air bubbles.
- Let the material cure for 30 to 45 minutes until set and warm to the touch.
- De-mold the coasters and sand the surfaces under running water with progressively finer sandpaper (from 120-grit up to 600-grit) to expose the embedded colorful chips.
- Wipe dry and coat with a food-safe wax sealer.
Tips and Variations
- Tip: Wet-sanding is essential to keep dust down while quickly uncovering the hidden terrazzo chips beneath the top layer.
- Variation: Integrate metallic gold leaf pieces alongside crushed chips for an elevated look.
