I purchased some resin off Amazon to make a little ornament for Christmas and after about 3 weeks with the resin still not curing fully (it’s about the consistency of cold caramel) I found myself here. Turns out the ambient temperature I had been working in was far too cold (it was about 45 degrees Fahrenheit). The manufacturer never mentioned anything in the instructions about what the ambient temperature had to be so I’m going to point my finger at them. I’m wondering if putting this in the oven (turned off where the inside is still fairly warm due to the pilot light) would harden the resin or if it’s too late?
I’m sorry to hear about your bad luck with the resin. I’m afraid at this point, putting it in the oven won’t do anything to make it cure. If you want to try again, having your room temperature in the low 70’s F is ideal for resin curing.
