What do these mean?

Recommended Posts

Penetration is a measure of the hardness of the wax using ASTM (American Society for Testing and Materials) method D1321. It's based on how far a needle penetrates into the material using a given amount of force. The lower the number, the harder the wax. 10 is on the harder side of average for the waxes that we typically see. It may indicate a fairly normal, narrow-cut paraffin.

Saybolt color is another test method (ASTM D6045) that determines how far the color deviates from colorless. +30 is virtually colorless or white. Fully-refined paraffins usually have that value or close to it.
