Does resin jewelry turn yellow?
Once cured, epoxy resins change with exposure to UV light (as most things on earth do!).

What is the difference between epoxy resin and UV resin?
Epoxy resin cures without any aids, UV resin only cures under UV irradiation. Its maximum layer thickness is 1mm. Epoxy resin allows layer thickness of up to 5cm per casting, on the other hand. UV resin always requires a UV lamp to cure and is therefore only suitable for smaller areas.

Why does resin have a shelf life?
All solvent-free epoxies have essentially unlimited shelf lives so long as they are stored in sealed containers. The resin may crystallize or the hardener may darken (YELLOW) but this does not affect its performance. If the material is more than a year old do a test to satisfy yourself that it cures properly.
