How to remove paper that’s stuck to resin?

Hey! I’m new to resin, so apologies if I use the wrong terms ^^

I was making this coaster yesterday, and I picked it up and pulled it from the mold since it seemed like it was sturdy (I made another coaster the other day and had no issues, but that one and the one pictured are different brands, so maybe that’s why my judgement was off??)

Anyways, I realized that it wasn’t done curing yet since it’s still bendy, so I placed it on the somewhat waxy(?) instruction paper from the old/used up resin from my previous coaster since I’d ended up using it as basically a workmat since I didn’t really have anything else. Later I went to take a picture of it to show my friend, but realized it was stuck to the paper. Pulling it off left me with this.

Is there a way to get it off? I tried burning it, scraping it off with a razor – neither really worked (as you can see in the pictures). Should I wait for it to fully cure before I try again? Or is there something else I should try?

Any advice is greatly appreciated!
