Yes, reusable candles have been invented, featuring designs that allow for the wax to be melted and reused multiple times. These candles often come with a refillable wax system or a container that can be reused with different wax blends. Innovations in materials and design aim to make them more sustainable and eco-friendly, appealing to environmentally conscious consumers.
The candle clock, although there is no exact evidence, was first used in 1206 AD in China and Japan.
The first candle clock, also known as a "candle clock," is believed to have been invented in China during the Tang Dynasty (618-907 AD). These early timekeeping devices consisted of marked candles that burnt at a predictable rate to indicate the passage of time.
The invention of the candle was a deliberate process, not accidental. Early civilizations across the world developed candles by using various materials such as tallow, beeswax, or whale fat to create a reliable and portable source of light.
The foot candle, a unit of illuminance, was developed by the American physicist and inventor, William Thompson, who is also known as Lord Kelvin. The term "foot candle" refers to the amount of light produced by a candle at a distance of one foot. While Thompson contributed to the understanding of light measurements, the concept of the foot candle became widely used in lighting design and engineering.
A reusable spacecraft is typically called a space shuttle or a reusable launch vehicle. These spacecraft are designed to be launched into space multiple times, reducing the cost of space missions.

A carved pumpkin with a candle is called a jack-o-lantern. It used to be a turnip with a candle in it. The Celts and Irish invented it but for different reasons.
