Anyone know how long it will last? I have pracs scheduled for over a 7 day period. If I make up the gel in bulk, will it be ok?

Sorry I am a bit late, just keep it warm. I always found if it set, it was hard to use.

I set it in petri dishes and stored in the fridge up to ten days, the students lightly press in the nails etc.
I was going to be away when they did the prac so I did it in advance. It worked fine and didn't change colour or go watery.

Thanks. It has seemed to survive the long weekend without discolouring so I assume it will be good to go this afternoon
