Rendering Beeswax and Making Your First Candles

Of all the byproducts of a beehive, beeswax might be the most extraordinary. It takes roughly 8 pounds of honey for bees to produce 1 pound of wax. Making something beautiful with it — a candle that burns for hours with the warm, sweet scent of the hive — is one of the quiet rewards of keeping bees.

Understanding beeswax

Fresh beeswax from cappings is pale yellow to almost white. Older comb wax is darker — golden amber to deep brown, picking up colour from propolis, pollen, and the cocoons of successive bee generations. All of it is usable.

Pure beeswax has a melting point of about 145°F (63°C), significantly higher than paraffin or soy wax. This is part of why beeswax candles burn so long and cleanly. Beeswax is also flammable above 400°F (204°C) — always melt in a double boiler, never in direct contact with a heat source, and never leave melting wax unattended.

Collecting and storing raw wax

The best beeswax for candles comes from cappings — the thin layer sliced off honey frames during extraction. Cappings wax is clean, pale, and minimally contaminated. Store in a sealed container or freeze until ready to render — cappings attract wax moths if left exposed.

Rendering: the solar method

For small amounts, solar rendering is the most effortless method. Build a simple solar melter: a shallow box lined with foil, a coarse metal strainer across the top, and a tray below to catch the wax. Cover with a pane of glass. Place raw wax on the screen, set in full sun at 45 degrees. On a warm day the interior reaches 150°F+ and melts the wax, which drips through the screen leaving debris behind.

Rendering: the double boiler method

For larger quantities, use a dedicated wax pot (never use for food again — wax is nearly impossible to clean) inside a larger pot of simmering water. Keep wax at 160–170°F; don't exceed 185°F.

Add raw cappings or broken comb. Stir gently as wax melts.
Ladle liquid wax through cheesecloth or a nylon stocking into a clean container.
For cleaner wax, remelt and filter a second time.
Pour filtered wax into molds. Allow to cool slowly — rapid cooling causes cracking.
Scrape off the bottom layer of "slum gum" (dark residue of pollen and propolis) and discard.

Expect to recover 60–70% of raw cappings as clean wax.

Choosing your candle format

Pillar candles: The most traditional form. Requires a rigid mold and a stiff wick. Beautiful results, more precise technique required.

Container candles: Easiest for beginners. Pour into wide-mouth mason jars — charming aesthetic, no mold needed, shrinkage is less critical.

Rolled beeswax candles: The absolute easiest. Purchase pre-made beeswax sheets, warm slightly, place a wick along one edge, and roll tightly. No melting required.

Tapers: Dip a wick repeatedly, building up layers. Meditative to make but time-consuming.

Making container candles: step by step

Wick sizing guide for beeswax:

Up to 2" diameter: CD-10 or ECO-4 wick
2"–3" diameter: CD-14 or ECO-6 wick
3"–4" diameter: CD-18 or ECO-10 wick

Beeswax requires larger wicks than other waxes — don't use wicks sized for soy or paraffin.

Step 1: Warm jars in an oven at 150°F. Attach wick tab to the bottom centre with hot glue. Wrap the top of the wick around a pencil laid across the jar rim to centre it.

Step 2: Melt wax to 160–170°F using double boiler.

Step 3: Let wax cool to 150–155°F before pouring — pouring too hot causes the wax to pull away from jar sides.

Step 4: Expect shrinkage and a sinkhole around the wick. Once the first pour has set completely (2–4 hours), do a small top-up pour to fill and level the surface.

Step 5: Once completely cool (allow 24 hours), trim the wick to 1/4 inch. Allow a curing period of 24–48 hours before first lighting.

Troubleshooting

Frosting (white, chalky surface): Slow the cooling process — place candles in a warm spot away from drafts. Cosmetic only, doesn't affect burn quality.
Tunnelling (wick burns down a hole): Wick is too small. Size up one wick size.
Mushrooming wick (large black carbon ball): Wick is too large. Size down.
Wax pulling away from jar sides: Poured too hot, or jar was too cold.

What to do with candle scraps

Save all trimmed wicks, cooled drips, and candle stubs and remelt for future use. Even small amounts of wax can wax thread, coat tools to prevent rust, condition wooden handles, or lubricate sticky drawers.

A candle made from your own bees' wax, burning on your table in November, is one of the most satisfying possible outcomes of a beekeeping season.
