Empty the peasl into a heat proof container, a sauce pan should do.
Pour hot water over the peasl, it has to be over 64º C or 147º F; freshly boiled water works well.
Watch the peasl turn clear, it is now ready to use, but be careful it could still be hot enough to burn you, make sure you use a wooden spoon or something similar to remove it from the water.
Shape the peasl, but be careful it can stick to fabrics and other plastics.
As it cools it will turn white and harden. You can see more at our YouTube channel: https://www.youtube.com/mypeasl
