Project Overview & Aesthetic Design
A dramatic, high-contrast coaster inspired by Spanish Nero Marquina marble. A deep, glossy jet-black resin base is fractured with fine, branching veins of metallic gold leafing.
Step-by-Step DIY Execution Guide
-
Mix 150ml of clear epoxy resin. Mix 85% with rich black resin paste (ensure it is fully opaque when held to the light).
-
Pour the black resin into four round silicone coaster molds, filling them almost to the brim.
-
Mix the remaining 15% clear resin with rich metallic gold mica powder and a drop of gold alcohol ink.
-
Drizzle the metallic gold mixture in jagged, lightning-bolt fracture lines across the black resin surface.
-
Use the low-speed, low-heat setting on a heat gun to gently blow and spread the gold veins, creating a shimmering, feathered lacing effect.
-
Torch the surface to remove bubbles and let cure for 24 hours.
-
Paint the outer edge rim with liquid gold leaf using a fine-detail flat brush.

Pro Crafter Tip
Angle your heat gun at roughly 45 degrees to blow the gold resin across the surface without pushing it down to the bottom of the mold.
