How to choose a candle jar
When choosing a candle jar, whether for yourself or as a gift, it's essential to think beyond just the price and scent. There are several other important factors to consider.
Burn Time:
The type of wax used greatly influences the candle's burn time. For example, soy wax and coconut wax candles jar generally burn longer than those jars made from paraffin wax. This can be a crucial factor in deciding which candle to buy and make.
Frosting Phenomenon:
Frosting refers to the appearance of white crystals on the outer surface of a candle, a common occurrence in vegetable waxes like soy wax.
Wetspot Phenomenon:
This occurs when the wax pulls away from the glass container, causing the surface to appear mottled or uneven.
Sinkhole Phenomenon:
This occurs when a hole forms on the surface of the candle wax, typically around the wick. It tends to happen when the wax contracts significantly, especially in narrower and deeper molds or containers. The likelihood of sinkholes increases if the candle hardens in a cold or windy environment.
Scent throw:
Throw is how well scent travels from a candle. "Cold throw" is how well scent travels from a candle before it is lit. "Hot throw" is how well scent travels after it is lit. Both are important to choose a candle. Typically, soy wax candle is better scent throw.
Wick size, flame size, and the tunnel effect
Wick size, flame size, and the tunnel effect are closely related. A large wick produces a large flame, while a small wick results in a smaller flame. If the flame is too small to melt the entire surface of the candle, the tunnel effect can occur, where the wax burns unevenly, leaving a ring of unmelted wax around the edge. On the other hand, if the flame is too large, it can cause the wax to melt too deeply, making the glass too hot. This can shorten the candle's burn time and pose a safety risk. Wick size is most important in this factor
