Project Overview & Aesthetic Design
A coastal-inspired geode coaster combining vibrant ocean blues, cobalt inks, and translucent icy resin, accented with floating flakes of genuine holographic silver foil.
Step-by-Step DIY Execution Guide
-
Mix clear resin and divide into cobalt blue, cyan shimmer, opaque white, and clear.
-
Place flakes of silver foil into the center of a round or geode silicone mold.
-
Pour clear resin in the center over the silver foil, and pour cobalt blue around the outer perimeter.
-
Fill the intermediate gap with cyan shimmer resin, drizzling a thin ring of opaque white along the blue-cyan boundary.
-
Gently feather the boundaries with a toothpick to create realistic agate rings.
-
Torch for bubbles and let cure. Paint the outer edge with liquid silver leaf once demolded.

Pro Crafter Tip
Crumble your silver foil into tiny flakes before placing it in the mold; large sheets will float to the top and create an uneven surface.
