Adding things to resin is an easy way to make your resin crafts and jewelry special. Your possibilities are endless! While there is so much you can add to resin, there are five things you should never set in resin:
Fresh flowers will turn colors in resin. They can do anything from go clear to turn brown after putting them in resin. If you want to use flowers in resin, you will need to dry and preserve them first. You can learn to do that here: How to dry flowers for using in resin
Anything you think you might want to get back out later
While photos, mementos, and heirlooms look great when embedded in resin, think twice before putting them in a resin casting. It will be almost impossible to get the item back out of the resin without destroying it in the process. Instead, make a copy of the thing if possible (especially easy in the case of photos, tickets, notes, etc.) and include that in the resin.
Fresh food items with high water content, like fruit, will rot and turn disgusting in resin. You must dehydrate the food first, and even then, it’s difficult to get all the moisture out to keep the food from rotting. This extra moisture will also keep your resin from curing. What can you do instead? Create a food lookalike with clay. Clay and resin go great together! You can see what I mean here: How to make a resin and polymer clay ring
Resin hates moisture, and some resins, like polyurethane resins, hate it more than others. It’s why I stress using colors explicitly designed for resin because the moisture in paints and food colorings can keep the resin from curing. If you want to change the viscosity of your resin, solvents like alcohol and acetone work better and are less likely to impact curing.
Bugs and other small specimens that aren’t entirely preserved
Like flowers and fruit, small animal specimens will rot if included in resin without preserving first. We have a great discussion about this topic in our forum that will get you inspired to give this project a try. How to embed a spider in resin.
