GlassCast 10 Cloudy/crystalised Resin

I started using a fresh container of GlassCast 10 about 10 days ago using about 2/3rds of the contents.

Today, when I went to use the remaining epoxy, I found is was severely crystallised and not pourable.

There has been no contamination with the hardner.

What has gone wrong, or is there a very short shelf life once the container is opened?

As Hanaldo says, the resin has got cold at some point and crystalised.  Sticking it on a hot radiator, oven at 50C or in a sink of hot water for a few hours (lids sealed) is usually enough heat energy to turn it back to a liquid.
