You newb, you need to wear nitrile gloves! And a ventilator mask rated for fumes! And you picked uv resin?! That stuff is so much weaker than epoxy that I wouldn't be surprised if it breaks again! Plus did you make sure to cure both sides? It's gonna be sticky if you just cured one side.......
...ahem, sorry resin crafts is my hobby, kinda got carried away there.
That said, this would've been a good opportunity for some kintsugi design, which could thematically make sense. "Yes, it broke, but it can still be beautiful"
