Why is my resin cloudy and not crystal clear?

The resin you received is cloudy and not crystal clear as described. In cold weather, it is normal for epoxy resin to become cloudy and lose its crystal-clear transparency. This process is called resin crystallization.

To stop the crystallization process, immerse the bottle or tube you received in a bucket or similar container, then pour hot water.

Wait about 10 minutes until it returns to its crystalline appearance.
