Mel, I’m unsure to be honest, but all I can say is I still have my Scrooge from Dec 2013 and he’s perfectly intact.

I only mix enough modelling choclate for what I need but if you want to mix more and know you AR not using it for a while, store it in the fridge. The longest I’ve kept modelling choclate so 3 months. If making for a client, I alway make fresh. For display work I use older stuff xx
