Results Discussion:  

The difference in wax hardness can be easily resolved with the Shore D durometer

A strong correlation was seen between room temperature and 25 Deg F measurements on the subset of waxes so the results at room temp should be representative of hardness at colder temperatures

testing method using the shore D durometer

1. A flat surface was created on the wax block by heating it against a waxing iron

2. Five measurements were taken at different locations on the wax block

3. Average result of the 5 measurements shown in the chart below

4. A subset of the waxes were placed in a 25 Deg F freezer and the hardness measured again when the wax was cold (2nd chart below)
