Carnauba contents can be calculated almost any way you choose, and some wax companies have used this to their advantage. So we came up with Flat Earth to prove that a 70% pure carnuaba wax wasn't much of a wax at all. But a pretty useless curiosity best used as a paperweight.
If you want a lump of almost-pure carnauba to fiddle with on your desk, or to impress your detailing mates with, then look no further. 30ml of unusable, BS-busting goodness.
