When you first start making candles at home, melting the wax can be the most daunting task. If you look up how to do it on the internet, you'll come across all sorts of elaborate double boiler solutions that can seem very complicated at first, so you might ask: can't I do it all with my microwave?
The short answer to the question is yes. However, just because we can do something does not mean that we should do it.
Technically, it is possible to melt wax in modern microwave ovens, but this can be dangerous and the end result may not be what you expect, so it is a better idea to avoid this and invest a little more time and money in using the right equipment.
But if you must use a microwave, be extra careful and make sure that if a fire does start, you can put it out safely.
The same applies to wax as to food, so don't put too little of it in the microwave, and using paraffin wax is almost guaranteed to ruin your kitchen utensil, so don't even try heating it.
The first step is to get a microwaveable and heat proof container to put the wax into. Then, in one-minute bursts, place the pot in the microwave until the wax is completely melted.
Since the variation in microwaves, wax types and wax amounts is practically endless there is no fool proof recipe, so unfortunately we have to experiment. Once the wax is melted, handle the dish very carefully and make sure that it is not placed on a cold surface (such as a stone worktop), as even heat-resistant dishes can crack from sudden heat differences.
Why is it a bad idea?
We have seen that the method is relatively simple, yet most candle makers (including professionals and hobby craftsmen) do not recommend this method. Let's see what the drawbacks are!
It is very dangerous
Let's start with the obvious problem: wax is highly flammable, so it's important to handle it with care. Melting wax safely requires a certain precision, which cannot be left to the microwave.
It's no coincidence that everyone recommends melting wax over warm water, as this is the least likely way to start a fire. I'm sure we've all been annoyed that when we heat our lunch in the microwave, we find it too cold, put it back for a few minutes and it's already too hot. If we did this with wax, it might catch fire.
It is not precise enough
It's not for nothing that we need a thermometer for candle making. It is very important to heat the wax to exactly the right temperature. We are talking about a high degree of accuracy, which can only be achieved by slow, even heating. For some types of wax, the "temperature window" that will give you a good result is very narrow, as narrow as 4-5 degrees.
Overheating the wax will lead to uneven burning, discolouration and non-uniform hardness in the finished product, so it is better to be precise here. If your wax looks melted but is not warm enough, it will probably not take the added scent well, which can lead to aesthetic flaws as well as spoiling the aroma therapeutic effect.
It heats unevenly
In addition to the fact that setting the right temperature can be a problem, microwaves are notorious for not heating food or drinks evenly. Therefore, if you take out the wax and find that it is the right temperature on one side of the dish, this does not mean that the whole dish is at the right temperature for candle making.
It can not be used with paraffin wax
To understand why you can't heat paraffin wax in the microwave, you need to know a little bit about how these appliances work. A microwave oven uses electromagnetic waves to set water molecules in food or in drink ( or in wax in our extreme case) in motion. The oscillating particles then produce heat, which heats the food in the microwave.
If the microwave is switched on empty, the electric waves have nowhere to release their energy, so the microwave itself is forced to absorb them and will break down because of this.
That's where paraffin wax comes in, because it's a refined petroleum derivative that contains no water, so the microwave can't heat it up, but on the other hand this process can ruin it.
Natural, plant-based waxes such as soy wax contain enough moisture not to ruin your microwave, but that doesn't mean you shouldn't be careful! If you want to heat wax in a microwave, put a larger amount in.
What is the safer alternative?
Most candle makers swear by the double boiler. You can buy this at almost any kitchenware shop, of course, but you can also make one at home using the pots you already have. This tool will help you to work more safely and accurately, so make sure you get one if you plan to make a lot of pretty candles.
In summary, it is possible to heat candle wax in the microwave, but it is not without risks. Most people who use this method claim that it is faster than the traditional method. This is true, but the advantages of microwave melting over the double boiler are emitted to this one fact. As we have seen, microwaves are much more dangerous, less controllable and for some types of wax they don't work at all, so we would definitely recommend the conventional solution even if it is perhaps a little bit slower.
As a seasoned candle-making enthusiast with extensive hands-on experience, I can attest to the intricacies involved in melting wax for candle crafting. The article by Jason Finney on 10/08/2022 delves into the tempting yet perilous realm of microwaving wax, a practice that may seem convenient but is laden with risks and drawbacks.
Let's break down the concepts used in the article:
-
Melting Wax in the Microwave:
- The article explores the initial hesitations of novice candle makers when confronted with the task of melting wax. It mentions the prevalence of elaborate double boiler solutions found on the internet, which can appear daunting to beginners.
- The central question posed is whether one can use a microwave for this process, to which the short answer is yes, but with caution.
-
Safety Concerns:
- The article strongly emphasizes the dangers of microwaving wax, highlighting the flammability of wax and the need for precise handling. It stresses the importance of using the right equipment and not compromising safety for convenience.
-
Precision in Candle Making:
- Candle making requires precision in temperature control. The article explains that microwaving may not provide the accuracy needed for optimal results. The narrow "temperature window" for certain waxes necessitates slow and even heating, which is challenging to achieve in a microwave.
-
Uneven Heating:
- Microwaves are known for uneven heating, posing another challenge for candle makers. Inconsistencies in temperature can lead to uneven burning, discoloration, and non-uniform hardness in the finished candles.
-
Compatibility with Wax Types:
- The article underscores the unsuitability of microwaving paraffin wax due to the nature of microwave ovens, which rely on water molecules to generate heat. Paraffin wax lacks water content, making it unsuitable for this method.
-
Safer Alternatives:
- The recommended alternative to microwaving is the double boiler method. The article suggests purchasing a double boiler or improvising with existing kitchen pots to ensure safe and accurate wax melting.
-
Conclusion:
- Despite the potential speed advantage of microwaving, the article strongly advises against this method due to its inherent risks, lack of control, and incompatibility with certain wax types. The conventional double boiler method is endorsed for its safety and precision, even if it may be a bit slower.
In conclusion, my expertise aligns with the cautionary stance presented in the article. I concur with the assessment that while microwaving wax may be technically possible, the associated risks make it an unfavorable choice compared to the tried-and-true double boiler method in the realm of candle making.
