zip dry glue

[mokkabella]

HI

Not sure if I am posting in the right board,, I got out of card making for two years lost my mojo and I am starting up again.. I was a glue and adhesive hoarder bought when on sale or coupon


I have a few zip dry glues that totally dried up . sunk 1/2 way down the bottle.
Is there any way to unplug it liquidfy it (spelling) again or its a lost cause

Thanks so much.\

ps they are still in their packaging

I kind of doubt it since its not a water based adhesive.
