Candlesticks, also known as candleholders, are devices used to hold candles in place. They are often used as decorative elements in homes or for special occasions, and are also used in religious rituals and spiritual practices. While candlesticks themselves are not porous, candle wicks are. The wicks are made of braided cotton, which has a porous structure that allows it to absorb liquids. This capillary action is essential for drawing up the liquid wax through the wick and keeping the candle burning.

What You'll Learn
Candle wicks are porous
The construct, composition, and geometry of the wick significantly impact the burn characteristics of a candle. For example, the number of fibre bundles, their size, and orientation contribute to the wick's stiffness and fuel capacity. The shape of the wick also plays a crucial role, with flat, round, and square wicks each offering unique burning properties. Flat wicks, for instance, tend to curl back into the flame, making them self-trimming.
Different materials are used for wicks, each with its own unique burning characteristics. While cotton is the most common material, wooden wicks have gained popularity in recent years for their visual appeal and the soft crackling sound they produce. Other materials used include paper, zinc, tin, and historically, even asbestos.
The type of wick used depends on the specific application. For example, birthday candles typically use twisted wicks, which burn faster due to their loose construction. In contrast, cored wicks are often used in jar candles, pillars, votives, and devotional lights to keep the wick upright during burning.

Candles use capillary action
Candle wicks are made of braided cotton, which makes them porous. Porous materials have lots of narrow spaces, and liquid candle wax has strong adhesive properties, which make it stick to certain surfaces. In narrow spaces, the adhesive forces between the liquid and the wall can become stronger than the forces of gravity acting downward on the liquid, causing it to move up into the narrow space. This process is called capillary action, and it is the same mechanism through which sponges can soak up water from a surface, seemingly against the forces of gravity.
Capillary action is essential to how candles work. When a candle is lit, the heat of the flame melts the wax near the wick, creating a puddle of liquid wax. This liquid wax is then drawn up through the wick by capillary action. Once the liquid wax reaches the top of the wick, it is heated further and vaporizes, turning into a hot gas. This vapour is then ignited by the heat of the flame and becomes part of the flame.
The process of capillary action in candles is sustained by the continuous melting of wax at the top of the wick, which provides more liquid wax to be drawn up through capillary action. As the liquid wax is drawn up the wick, it is heated and vaporized, creating a continuous supply of fuel for the flame. This process continues until one of the components of the flame (fuel, heat, or oxygen) is removed. For example, if you let the candle burn up all the wax, or if you blow out the candle to remove the heat, or if you use a candle extinguisher to remove the oxygen.
It is worth noting that candle wicks have been designed to self-regulate their length. Modern candle wicks are braided with a flat braid, which makes them curve as they burn. This ensures that the tip of the wick dips outside of the flame, giving it enough oxygen to burn and thus keeping itself at a constant length. This design eliminates the need for wick trimmers, which were commonly used in the olden days to trim the wick and maintain its length.

Candles are used in trading charts
Each candlestick has three components: the real body or body, shadows or wicks, and colour. The body represents the open-to-close range, with long bodies indicating strong buying or selling pressure, and short bodies suggesting indecision. Shadows or wicks extend above and below the body, marking the highest and lowest prices reached during the period and offering insights into market volatility. The colour of the candlestick indicates the direction of market movement: a green or white body indicates a price increase, while a red or black body shows a price decrease.
Traders use candlestick charts to identify bullish and bearish patterns, which help predict short-term price movements and potential market turning points. For example, the hammer candlestick pattern, which forms at the bottom of a downward trend, indicates a potential shift from a downtrend to an uptrend. Conversely, the shooting star pattern, which forms in an uptrend, signals a point of resistance and potential market decline.
While candlestick charts are powerful tools, they have limitations and should be used alongside other technical analysis tools for confirmation. Their predictive power is mostly limited to the short term, and they can produce false signals, so confirming patterns with support, resistance, and other tools is essential.
Regarding the porosity of candle sticks, it is important to distinguish between the wicks and the wax. Candle wicks are made of braided cotton, which makes them porous and able to absorb liquids through capillary action. However, the wax itself should not be porous, as this can cause issues with fragrance absorption and the overall quality of the candle. Additionally, when selecting a container for a candle, it is important to avoid porous glass to prevent safety hazards.

Candles are used in religious rituals
While candle wicks are porous, with their braided cotton structure allowing them to absorb liquids, candles themselves are used in a variety of religious rituals.
In Christianity, candles are commonly used in worship as a symbol of the light of God or, in certain denominations, the light of Christ. They are also lit during religious services, liturgical processions, evening prayer ceremonies, and funeral processions. The Paschal candle, for instance, is lit during Easter as a symbol of the risen light of Christ. In the Catholic Church, votive candles are burned as an offering, indicating that the person lighting the candle is seeking a favour from the Lord or saint.
In Judaism, a pair of Shabbat candles are lit on Friday evenings before the start of the Sabbath. A special candle with multiple wicks is lit for the Havdalah ritual, which marks the end of the Sabbath and the beginning of a new week. Candles are also lit during the Festival of Lights, or Hanukkah, to commemorate the rededication of the Temple in Jerusalem.
In Buddhism, candles are placed before shrines or images of the Buddha as a show of respect. They are also used in meditation and prayer, with the light of the candle representing the light of the Buddha and the path to enlightenment.
In Hinduism, candles are used in daily rituals of worship and offering, also to represent the light of the gods and the connection between the individual and the divine. They are also lit during religious festivals and ceremonies, such as Diwali.

Candles can be made with soy wax
While candle wicks are porous, I could not find sufficient information on whether candle sticks are porous or not. However, I can confirm that candles can be made with soy wax. Soy wax is a plant-based wax that is a popular alternative to paraffin wax, a byproduct of crude oil that emits chemicals such as toluene and benzene when burned. Soy wax is cheaper to buy in bulk, offers a long burn time, and is easy to clean up with hot water, soap, or rubbing alcohol. It also transmits the scent of essential oils well, allowing for a wide range of personalisation options.
To make a soy wax candle, you will need a heat-proof container, a pot, a thermometer, a wooden stick, and a wick. First, place about two inches of water in the pot and set your heat-proof container on top of it. Then, add 1.5 cups of soy wax flakes to the container and bring the water to a boil. Reduce the heat to medium-low until the wax completely melts. Remove the pot from the heat and add essential oils to the wax, stirring with the wooden stick. Centre the wick in the jar using a wick sticker, secure it with glue, and thread the top through a clothespin. Set the clothespin on top of the jar, centring the wick. Once the wax has cooled and reached a smooth consistency, it is ready to be poured into the jar. Allow the wax to harden for about 1-2 hours, then trim the wick and light your candle.
There are a few things to keep in mind when making soy wax candles. Soy wax is known to shrink while cooling, which can result in holes forming in the candle container. To avoid this, you can pour the wax at a lower temperature or heat the container before pouring. It is also important to stir in dye and fragrance oils thoroughly to avoid air bubbles in the cooled candle. Additionally, using too much fragrance oil can affect the burn time of the candle. Finally, when cleaning your jars for reuse, be sure to wipe them with isopropyl alcohol and a clean paper towel before wicking to ensure they are ready for the next batch.
