Epoxy Resin
From Makerpedia
1. Put on gloves!
Resin and resin hardener are uncomfortable on your skin, but if you do get any on you, use rubbing alcohol (or hand sanitizer in a pinch) to get it off.
2. Prepare your space
As hard as resin is to get off your skin, it's even harder getting it off most surfaces. Lay down a silicone mat, plastic wrap, or vinyl. If none of these are available, spread multiple layers of craft paper or scratch paper.
3. Mix the resin and hardener
In a disposable plastic cup, mix equal parts epoxy resin and hardening agent (the two matching bottles).
Tips
-Be as precise as possible when you measure them out. -Stir more than you think you need to - but stir gently to minimize air bubbles.
