Candles

A candle is a portable source of light, traditionally made from wax or tallow with an embedded wick that burns to produce a steady flame. Candles have been used for centuries for illumination, heat, and ceremonial purposes. Today, they are more often used for ambiance, decoration, fragrance, and rituals than for lighting.

History

Candles date back to ancient civilizations. Egyptians used rushlights soaked in animal fat as early as 3000 BCE. The Romans are credited with developing the wicked candle around 500 BCE, using tallow (rendered animal fat). In China, beeswax candles appeared during the Qin Dynasty (221–206 BCE).

During the Middle Ages, candles made from beeswax became common in Europe, especially in churches. Beeswax burned cleaner and smelled better than tallow, but was expensive. Tallow candles were cheaper but smoky and unpleasant.

The 19th century brought major advances. Stearin, a hard, clean-burning wax, became popular in Europe. Paraffin wax, developed from petroleum refining in the 1850s, revolutionized candle making and remains widely used today.

Materials

Wax

Common waxes include:

Paraffin wax – the most common, made from petroleum byproducts.
Beeswax – natural, clean-burning, with a honey scent.
Soy wax – made from hydrogenated soybean oil; popular in eco-friendly candles.
Palm wax – derived from palm oil; produces textured surfaces.
Coconut wax – smooth-burning and often blended with other waxes.

Wick

Wicks are typically braided cotton. Some wicks include a paper or metal core for rigidity. Wick type and size affect how the candle burns—too small and the flame drowns; too large and it soots or tunnels.

Uses for Candles

Lighting: Historically, candles were essential for illumination.
Aromatherapy: Scented candles, often infused with essential oils, are used to create mood or relieve stress.
Ceremonial and Religious: Candles are common in rituals, from church services to birthday cakes.
Decorative: Used to create ambiance in homes, restaurants, and events.
Emergency: Kept as backup light sources during power outages.

Types of Candles

Pillar candles: Thick and free-standing.
Taper candles: Long, slender, used in holders.
Tea lights: Small, round, often in metal cups.
Votive candles: Short, cylindrical, meant to burn in glass holders.
Container candles: Poured into glass or ceramic jars.
Floating candles: Designed to float on water.
Novelty candles: Shaped for aesthetic or humorous appeal.

Candle Safety

Candles are an open flame and can pose fire hazards. Basic safety tips:

Never leave burning candles unattended.
Keep away from flammable materials.
Trim the wick to 1/4 inch before each use.
Use a stable, heat-resistant surface.
Keep out of reach of children and pets.

Environmental Impact

Paraffin candles release small amounts of soot and potentially harmful compounds when burned. Plant-based waxes like soy and coconut are renewable and generally burn cleaner. There is increasing consumer interest in sustainably sourced, non-toxic candles.

Industry and Market

The global candle industry spans mass-market brands and artisanal makers. Candles are often sold in gift shops, home decor stores, and wellness retailers. Scented candles, in particular, represent a major market segment. Social media and e-commerce have fueled the rise of niche, handcrafted candle brands.
