Just an interesting note: finally got around to working over a based and painted Lizardman army I had picked up on fleabay.
Overall, the paintjob was serviceable: I cut my teeth with Howard Hues paints, so my tendency is to lean toward the matte and the drab. Well, this one is quite colorful... but I suppose it's alright for lizzies.
But the basing/flocking job was, let's say enthusiastic. Even the Kroxigors were wading up to their ankles in brown sand, with some sort of fairly rigid glue holding it all together. The worst part was that the flocking had even gotten glued to the bottoms of the bases, perhaps to a depth of 1mm or 2mm.
I started probing with the thumbnail clipper, got some of the sand to come off... broke some bases and popped a couple of strips off... then I figured it couldn't hurt to dip 'em in water... got some more sand off. Looking like a nasty job, but the water seemed to help somewhat.
And then the teapot started whistling...
To conclude a long story; 100C was, evidently, above the expected operating conditions for whatever glue had stuck these miniatures on. It remained sticky, but became quite pliable, and about 90 minutes later I had about 2k points worth of painted lizardman strips ready for touch up, dry-brushing, and rebasing.
As MOK would say: I'm chuffed.
FWIW, I've been getting in the habit of using Elmers glue and wooden bases -- seems perfectly serviceable under most conditions... and quite easy to rebase should the need arise: why not?
