When we're talking about resin for art or crafting, we're referring to epoxy resin. Epoxy resin is a clear liquid plastic made of up two parts: resin and hardener. When the resin and hardener are mixed together, a chemical reaction occurs that takes it from a liquid to a hard, shiny solid. Resin was used mainly for industrial applications -- that is, until artists discovered that a shiny coat of resin makes color pop, giving paintings and photographs an unparalleled depth and a sleek, modern finish. In recent years, resin art has soared in popularity and is being used to create jewellery, crafts, coasters, flow art, mosaics, charcuterie boards and so much more.
