If the beeswax is in a block, grate it over a bowl until there is 1/4 cup. If it is really cold, microwave the block for 20 seconds to make it easier to grate.
Add metal rack to pot. Add approximately 2 cm water and bring to a simmer.
Add beeswax, grapeseed oil, honey, and shea butter to glass measuring cup.
Set measuring cup on rack in pot with simmering water and leave for approximately 10 minutes or until beeswax has melted. Mix with spoon.
Pour melted mixture into sterilized glass jars. Allow mixture to cool.
