Hi DB, in the same boat as I have 2 pots and went to use one of them today and it was as solid as.....?
Will it soften up if you gently heat the container by immersing in some hot water for a period of time perhaps? Or would I do better leaving it out in the sun and use some natural solar energy to soften things up? Not much sun around today so that wasn't an option.
Cheers, Waz
