My daughter is a nun at an Abbey in Connecticut and is responsible for making all of the candles used by the religious community. A benefactor donated several hundred pounds of Carnauba wax (in powder form), thinking it could be used in the candle making process, but it can not be used for that purpose. I thought the wax could be processed into furniture polish but I do not know the best way to proceed. One suggestion I've received was to melt a mixture of bee's wax and carnauba in turpentine, another suggestion was to use mineral spiritis and naphtha as the solvents. What would you suggest?


The answer depends on what you mean by "turpentine." Naphtha and mineral spirits are both petroleum distillates used, for example, as paint thinners. Something commonly referred to as "turpentine" is also used as a paint thinner. If that's what you mean by "turpentine," it makes no difference whatever (all three are quite flammable!)

BUT, the paint thinner "turpentine" is more correctly referred to as "oil of turpentine" or "spirits of turpentine" and is distilled from actual turpentine, which is a more-or-less viscous natural resin. I came across a simple recipe for a beeswax/carnauba wax polish, but it apparently calls for actual turpentine, not spirits of turpentine or oil of turpentine (which the maintainers of the site I reference call "rectified turpentine"). Some experimentation may be in order.

My Scientific Wild Guess (as a craft-impaired person) is that the use of a paint thinner like naphtha or oil of turpentine is not the thing you want to do. Apparently actual turpentine is a hardening agent (like a varnish, and it's certainly used in some varnishes) and gives the wax finish more durability.

According to the Merck Index, turpentine is "gum from Pinus palustris and from other species of Pinus, Pinaceae."
I'm glad to know of another (presumably) more-or-less recent vocation to the religious life; one is always afraid that the communities Thomas Merton called "the center of the universe" will die out for want of novices. Please pray for me and ask your daughter to do so.
