Frozen paints?

[Verderer]

So I ordered some Army Painter acrylics and other stuff online from Germany to Finland, and the parcel arrived just now. Only the paints seemed frozen or very close to it anyways, I could see the agitator balls in the varnish bottle, and they didn't move when I tried shaking. Once they were in room temperature, they started moving and mixing fairly quick...

But the question is, do acrylic paints like this survive after being in extreme cold? It's been around -15 to -22 Celcius this week locally, and seems like the parcel was kept in a cold container or something, cause the paint bottles like ice at first.

Found two Reaper threads. Basically, if the paint gets clumpy, it's separated beyond use. Test the paints on some sample mini's?

Yeah, I think I read one of those... By the way, I contacted the seller, and they said not to worry, as according to them the Army Painter paints contain 'anti-freeze'

I wonder if that really is the case, and what the substance is... but I will try to get some hobby time this week to try out the paints.

If the agitation balls inside aren’t moving, I don’t think the antifreeze was doing it’s job… At a minimum the contents were gelled, if not frozen. Even with antifreeze in vehicle radiators there’s a point where coolant freezes (around -40 Celsius, depending on concentration) - that’s why vehicles in places like Canada (and I am assuming Finland?) have block heaters as a standard feature to prevent engines from failing in winter.

I really hope your paint turns out to be okay!

So yeah, I tested the paints just now, and they're all perfectly fine.

I’m glad to hear that they turned out okay! I would suck to have a batch of new paint be unusable.
