Glasscast 10/50 curing issue

Doing a river table indoors (have made a couple previously) and did the first pour yesterday about 6pm.
Mixed for 15 minutes and used an electric drill with a mixing tool attached. Pour is about 15mm - 20mm. Final depth is going to be 30mm.
Problem I’m having is getting it to the B stage.
Having done this before it was at the B stage after 24hrs but it’s now 24hrs and it’s nowhere near setting.
Remnants in the pot I used for mixing is still gloopy.
Now, I would say room temp was about 12degs to 15degs yesterday evening in the front room.
Do you think it just means it’s likely to take longer to get it to the B stage.?

Thanks. Should still be ok though shouldn’t it?Just take longer to cure?

Like above, you need at least 20°C for a proper cure, at 15°C the resin wont even want to start curing in most cases.
Nothing lost here, put it somewhere where it is a bit hotter and it will start to cure, only problem you might have is moist that got onto your resin after such a long time exposed, but is a minor problem that can be solved mostly by sanding if needed.
