Waxing, waterproofing and polishing

The bulk of the demand, and the least of the writing

Candles and casting get the attention. Across most societies, most beeswax went into ordinary maintenance: waxed thread for sewing leather and sails, waxed bowstrings, waterproofed cloth and boots, protected wood and metal, lubricated drawer runners, saw blades and nails, and sealed vessel mouths and stoppers.

• Waxed thread, which resists rot, holds a knot and passes through leather without fraying — the standard in shoemaking, saddlery and sailmaking.
• Waterproofing for canvas, boots and cordage, generally as wax blended with oils or fats.
• Polish for wood, leather and metal, where wax fills the surface and takes a shine without a hard film.
• Sealing jars, amphorae and stoppers, keeping air and moisture away from what was inside.
• Protecting metal from corrosion — a use that survives in conservation practice today.

Why wax rather than something else

Beeswax is water-repellent, chemically stable, workable at hand temperature, harmless to skin and to most materials, and does not go rancid the way animal fats do. For a pre-industrial household or workshop it was the one substance that could waterproof, lubricate, protect and seal, which is why it appears in inventories of almost every trade.

The non-rancidity matters more than it sounds. Tallow and oils will do many of these jobs and then, over months, go off — souring the thread, staining the cloth and attracting vermin. Wax simply stays as it is. For anything that had to be treated once and then left alone for a season, that stability was the whole argument, and it is why wax turns up in maritime, military and agricultural contexts where nobody was going to reapply anything.
