How to tell if flex-con (or acrylic) has been frozen

After the flexcon thaws out it looks like water with soap flakes floating in it Also when you put your finger in flex, it should feel sticky. If it has frozen, throw it away. Most places keep their flex in a heated space

The state of Virginia uses Kaufman products from Baltimore and every time I have used Kaufman it had been frozen.

They gave me a free bucket once to try and it had been frozen. I complained and they gave me another bucket that also had frozen. They probably make a good product, but when I tried it, it had frozen. I wouldn't buy it unless you can open the bucket first.
