As a young, internationally successful company, Wisefood has set itself the goal of offering consumers particularly sustainable products. These often consist of high-quality and natural materials with a good CO2 balance and are healthier to use or consume than chemically contaminated alternatives. But we want to offer more than just top products. We would like to offer you ideal purchasing advice so that you can make a conscious decision for or against a specific product. If you want to buy pillar candles, then in the following article you will find everything you need to know about their composition, quality, use and ideal use. We'll also let you know what to do if your firing products don't burn properly or produce too much soot.
Christmas time is candle time - no problem with sustainable candles!
Who wouldn't miss them? Cozy lights on the Advent wreath that make Christmas really contemplative. According to a recent Statista survey, 30% of Germans even decorate their Christmas tree with real candles.  The fact that candle products are so popular is no longer a secret. On average, Germans consume 3.1 to 4.0 kg of candle products per year and are only just behind Denmark, the undisputed European champion with a candle consumption of 4.3 kg per capita!  But what makes the cozy lights so popular now? Whether pillar candles, candles in a glass or on the Advent wreath, they spread a "hyggelic" atmosphere, create warmth and sometimes great smells and remind us of nature with their real fire.
How do I recognize high-quality candle products?
Whether large or small, as a decoration or as a gift, not all candle products are the same and so it applies when choosing the cozy lights some things to consider. If you want to buy a high-quality product, you should first think about the ingredients in your torch.
The majority of all candle products today are made from paraffin. This is a by-product that occurs during crude oil production and, due to its fluid, flammable, odorless and tasteless properties, established itself early on as an ideal raw material for candle wax.  Paraffin is particularly cheap and is produced industrially using the powder pressing process. In this way, costs can be kept low. However, the use of paraffin also has its price: Crude oil is not a sustainable raw material and not every responsible consumer wants to share the environmental impact associated with its extraction. Studies have also shown that harmful substances can be released when inferior-quality paraffin candles are burned. These are, for example, alkanes, alkenes, ketones, toluene or benzene.  Finally, paraffin has a low melting point. Soft paraffin already melts at temperatures from 45° Celsius, which means that it can be deformed by the warmth of your hands or by being in a sunny window. Ultimately, candles with harmful ingredients soot more often, as these are released during the combustion process via the liquid candle wax and visibly evaporate in the air.
If you want to look around for a healthier alternative that does not harm nature or your own health, you are well advised to use stearine candles. Stearin is a natural product.This can be made from both animal and plant-based substances and therefore has a significantly better environmental balance, depending on the exact origin. However, when buying sustainable stearin candles, consumers must pay attention to the small print. If the products are made from palm or soy waxes, it is often not possible to guarantee that no vegetation was destroyed to obtain the raw materials. Palm plantations and soybean fields destroy rainforests in many parts of the world and limit biodiversity when large areas of agricultural land are cleared for their cultivation and only used for monocultures.  Stearine candles made from locally renewable raw materials, such as rapeseed, are therefore a good alternative. However, stearine also has other positive properties. It is harder than paraffin and therefore has a higher melting point between about 55° and 70° Celsius.  Burning lights made from this raw material are therefore more dimensionally stable. Since stearin candles are often manufactured using more complex casting or drawing processes, this also has a positive effect on the burning time, which is significantly longer than that of paraffin candles. Stearin candles also burn with significantly fewer pollutants and therefore do not release any harmful substances when consumed.
What other criteria should I consider when choosing my candles?
In addition to the ingredients and the ecological origin, other factors are important that relate to the use itself. At Christmas, many consumers ask themselves what size candles they need for their Advent wreath and how they can be securely attached. The choice of color also plays an important role. So what do we have to pay attention to when we want to light a candle for the festival?
The ideal candle size
Usually it is suggested that one and a half times the ring size is used as a criteria for the candle size itself.  Both stick and pillar candles are suitable shapes, with a pillar candle usually promising a significantly longer burning time due to its larger diameter and thus having a better chance of lasting until Christmas Eve. For example, in our Wisefood range we offer sustainable pillar candles in white. Our large pillar candles are 13 cm high and 6 cm in diameter. Due to their high-quality ingredients and production processes, they burn for around 41 hours. If you want to decorate a smaller wreath, you can use our small pillar candle with the same diameter and a height of 9 cm. Both variants are 100% free of paraffin wax. This information is important because in the EU it is permissible to add up to 10% paraffin to stearin candles without this being subject to declaration! 
A Safe Fortification
Of course, open fire should never be left unattended. This also applies to the Advent wreath, even if the doorbell suddenly rings at breakfast on Saturday morning! But in addition to general tips on how to behave, secure attachment is also important in order to provide a certain level of fire protection. A perfect security measure is to buy self-extinguishing candle products at the point of purchase. At Wisefood, we do our part by offering sustainable candles that are made with patented SafeCandle technology and are therefore particularly safe to burn. In addition, consumers can use a so-called three-legged candle plate. This is a device that can be attached to the wreath on one side and has wire pins on the other side, onto which the pillar candle is speared and thus has an optimal hold.If you only want to use small tea lights, you can also create safety with the candle in the glass. However, care should be taken to ensure that this is also securely fastened (or glued) and is therefore mounted non-slip.
The right color
Consumers might initially assume that the color of their firing products has less of an impact on the firing properties than, for example, the ingredients, and only plays a role in the selection as decoration for your own four walls. Nevertheless, it is worth giving a little thought to the choice of color, or more precisely, the coloring. You have already learned that the manufacturing process can affect the quality and duration of the burn. While cheap products are often manufactured using the powder pressing process, their appearance is “spiced up” with additional production steps, for example clear or colored lacquers that are applied to the finished pressed candle products using a dipping process.  High-quality natural candles, on the other hand, are made with colored wax, which is poured into a mold. Here the wick is already clamped into the mould. Burning lights manufactured using the casting process often have a longer burn time and better durability. However, you should note that some colored candles are not UV-resistant and should therefore be stored in the dark until they are used.
How do I get the best quality out of my candles?
Whether you're buying a jeweled candle, a scented candle, or a candle for funerals and memorial services, you want a long one Ensure burning time and clean, soot-free burning. Here are a few tips you can use to get the best result when lighting your firing products.
Firstly, the candles should consist of high-quality ingredients and ideally be made using a casting or drawing process. Second, the wick should match the fuel. For example, if you want to make candles yourself and use stearin, the stearic acid can easily attack a normal flat wick. If the stearin candle is not to be lit immediately and is only used later, a special stearin wick should be used.  Otherwise, a normal wick could break off and the candle would no longer be usable.
While good raw materials ensure soot-free burning, you can support this effect by not letting the wick get too long and making sure the burning time is right. Especially with pillar candles made of stearin, it takes a while for the material to heat up. If only a short burning time is planned, the stearin candle burns out hollow and starts to soot faster with a long wick. In this case, table candles, for example, are a good alternative, which we also offer at Wisefood. These are ideal for short burning times. You can also check the wick length if your candle isn't burning properly and make sure it's not in a draught. With these tips, nothing should go wrong when burning!
Can I also make candles myself?
Of course it is also possible to make cheap sustainable pillar candles yourself. All you need is the right material and a bit of skill. The advantage of homemade candles is their individuality, which can be expressed even better with the right manufacturing process. Many people like pillar candles with a rustic look. In order for a firing product to be called rustic, it must be colored and hand-cast.But while most colored pillar candles in Germany are made from 100% paraffin wax, you can make a sustainable gift yourself from colored stearin wax. In this case, you should not only pay attention to the right stearin wick, but also add some shrinking wax. This influences the surface structure of your candle and, depending on the mixing ratio of stearin and shrink wax, gives it the desired rustic look. The shrink wax itself is essential, otherwise it would be impossible to get your cast stearin candle out of the mold once it has hardened. If you add approx. 2% shrink wax, you get a crystalline and glass fiber-like surface, which has a beautiful structure, especially with colored wax. If, on the other hand, you increase the proportion of shrink wax to up to 5%, the structure will resemble that of a smooth paraffin candle. 
By the way: If you want to make a candle in a jar yourself, cast oil candles with a floating wick are ideal for this. Use cooking oil for this, because this has the longest burning time of all oil candles at approx. 20 hours per cm.
Can a candle actually light itself?
What seems a bit like a magic trick also has its downsides and poses a not inconsiderable risk of fire. It is true It is not possible for a pillar candle to simply ignite itself without any source of fire, but spontaneous re-ignition of a candle that has actually been extinguished is possible under certain conditions. To avoid this, a few tips should be observed.
In order to understand self-ignition, it is first important to explain how a candle burns down in the first place. The wick connected to the wax is heated when it is lit and the heat transfer also liquefies the candle wax that is in the immediate vicinity of the wick. In the liquid state, this rises in the wick, where it reaches the hottest point of the flame. Here the wax changes into a gaseous state and evaporates. So while it appears as if the candle is getting smaller and smaller and dissolving into nothing, the wax initially only changes its state. If a burned product is blown out after a certain time and if enough wax has liquefied by then, white steam will be visible above the wick for a short time. These are the ones that can ignite again for a short time if they come into contact with fire again.
In this case, the fire uses the white vapor as a medium to work its way back to the liquid candle wax in the wick - in this case the product of combustion would appear to re-establish itself without apparent contact of the wick with fire ignite. However, avoiding such a risk of fire is easy. In order to extinguish candles safely, the wick should be pressed into the liquid wax and not blown out to avoid the formation of clouds of smoke. If clouds of smoke have formed after blowing out, good ventilation helps. After that, even if a flame is re-ignited, there should no longer be any risk of a combustion product igniting again as if by itself.
