Resin creates glass-like coasters, tumblers, keychains, pressed-flower bookmarks and river-style trays. There are two main types. Two-part epoxy is mixed from resin and hardener at a set ratio and cures over hours or days. UV resin cures in minutes under a UV lamp but only in thin layers, so it's ideal for small jewelry pieces.
Resin rewards patience: measure precisely, mix thoroughly, and give it time.
Supplies worth knowing about
Epoxy resin kits
Check the mix ratio, maximum pour depth and cure time. Coating resins and deep-pour casting resins behave differently.
UV resin & lamps
Great for bezels, charms and quick fixes. Cure in thin layers so the light reaches all the way through.
Silicone molds
Coasters, trays, keychains, letters and spheres. Glossy molds give glossy finishes.
Mica powder & alcohol inks
Mica adds shimmer; alcohol inks create cells and petri effects. Use colorants designed for resin.
Mixing cups & stir sticks
Graduated cups make ratios easy. Reusable silicone cups peel clean once cured.
Gloves & respirator
Nitrile gloves are a must. Follow the manufacturer's safety data sheet on ventilation and respiratory protection.
Pro tip: Keep resin tools separate from kitchen tools, and cover pieces with a box while curing to keep dust and pet hair out.
Know before you buy
Can I pour resin in my garage?
Resin generally wants a warm room, and many manufacturers recommend working around typical indoor room temperature. A garage in a northern winter or a hot, humid summer can cause cloudy, sticky or rushed cures. Follow your resin's temperature and humidity guidance.
Is resin food safe?
Only if the manufacturer specifically states it is when fully cured, and even then usually only for incidental contact. Don't use resin pieces as cutting boards.
How do I get rid of bubbles?
Warm the bottles before mixing, stir slowly, and pass a heat tool or torch briefly over the surface.
