I'm using a pan witn a rubber seal... you think water is still getting in? I'll know here in a few hours I guess..Could well be that, could also be some water ice in there, could be final product with water ice crystallised around it ( I'm only saying that because some of the blobs look quite like ice, but it's not the best photo to be fair ) in which case let the water evaporate before assuming your DMT melted. Top left looks like definite signs of DMT crystals though.
