Candle tunneling, a common issue in candle burning, describes the phenomenon where a candle burns down the center, leaving a ring of unused wax around the edges. This inefficient burning wastes wax and can shorten the candle’s overall lifespan. A typical example is a candle that, after several uses, has a narrow, deep hole burned through the middle, while a substantial amount of wax remains unmelted on the periphery.
Avoiding this occurrence is important for maximizing a candle’s value and ensuring a consistent fragrance release. Fully melting the wax pool to the edges on the initial burn and subsequent uses creates an even burn, optimizing the candle’s performance and extending its longevity. Historically, techniques to achieve this have been passed down through generations of candle makers and enthusiasts, recognizing the economic and aesthetic advantages of a complete wax melt.
