Velas

Velas are solid forms of wax with a wick used to produce light and, in many cases, fragrance. They may be plain or colored and may include scents or decorative elements. The wick draws melted wax by capillary action to sustain combustion. The container can be a glass jar, metal holder, or molded block.

Materials: Most candles use paraffin wax derived from petroleum; alternatives include beeswax, soy wax, palm wax, or blends. Wicks are usually braided cotton; certain designs use wooden wicks. Fragrances or essential oils are added for scent.

History: Candles have ancient origins, with tallow or rushlights used in ancient times; beeswax candles were valued by the Romans and medieval Europe; mass production of paraffin candles began in the 19th century, enabling cheaper and more consistent products; scented and decorative candles emerged in the 20th century.

Uses: Lighting, religious and ceremonial functions, mood and aromatherapy, decorative elements in homes and events; used in emergency lighting during power outages.

Safety and environmental: Candles are a fire risk; never leave burning candles unattended; place on heat-resistant surfaces away from flammable materials; trim wick to about 5-7 mm; extinguish with a snuffer; choose lead-free wicks; consider eco-friendly waxes to reduce petroleum reliance.
