Candle Making Supplies: Your Questions Answered

If you’re just starting out with candle making, the practical questions pile up quickly. This page gives straight answers to the ones UK beginners ask most about candle making supplies — wax, wicks and fragrance, with links to the full guides where you need more detail.

Which wax is the easiest for a complete beginner to use in the UK?

Soy wax is usually the best starting point for UK beginners because it melts at a lower temperature and adheres well to glass containers, reducing the risk of “pull-away” rings. It is forgiving to work with and gives a smooth top finish, making it a low-maintenance option for your first batch.

Should I use paraffin or soy wax for my first candle?

Paraffin wax delivers the strongest hot scent throw, making it the go-to choice if you are chasing a strong aroma, but it requires a higher melt temperature than soy. Soy wax scores higher on ease of use because it is easier to clean and less prone to cracking jars, so it is generally the safer bet for a first project.

Why is my soy candle sweating oil on the surface?

Sweating oil on the surface usually means you have added too much fragrance oil for the wax to hold, pushing the load past what the wax can safely absorb. This happens because the wax cannot bind the oil at that concentration, leading to pooling and a loss of stability.

What is the correct fragrance load for soy wax?

The correct fragrance load depends on the specific wax and oil you are using, so you must always check the supplier’s recommended percentage on the bottle or technical sheet. You should weigh your wax first to establish a clear total, then add the fragrance amount based on that guidance to avoid exceeding the wax’s capacity.

How do I choose the right wick size for my jar?

Picking the wrong wick size leads to problems like tunnelling, soot, or a melt pool that never reaches the edges of the jar, so it is crucial to match the wick to your specific wax and container. You need to find a balance where the wick is strong enough to pull melted wax up but not so large that it burns hotter than the wax can handle. Full details in our Ultimate Guide to Candle Wicks: Choosing the Right Size & Type UK.

Why does my candle burn with a tunnel in the middle?

A tunnel forms because the wick is too small or the flame isn’t hot enough to melt the entire surface of the wax, leaving the edges untouched. This results in a hollow tunnel in the centre and wasted wax, which is essentially a fuel line issue where the straw is too thin to draw enough liquid. Full details in our Why is My Candle Tunneling? Causes & Solutions for Even Burns UK.

Can I use a drinking glass as a candle container?

Regular drinking glasses will almost certainly crack when exposed to the 70–80°C melt temperature of soy wax due to thermal shock, so you should never use them for candle making. Only tempered, heat-resistant glass is safe to use, as it can survive the high heat without shattering. Full details in our Selecting Candle Containers for Beginners: Jars, Tins & Safety UK.

Are metal tins better than glass jars for beginners?

Tin containers are generally the safest and most forgiving option for beginners because they are metal and won’t shatter if they fall or overheat, unlike glass jars. They are lightweight and handle outdoor drafts well, making them a reliable choice for first-time makers. Full details in our Selecting Candle Containers for Beginners: Jars, Tins & Safety UK.

Should I pour my wax at Fahrenheit or Celsius?

Most UK suppliers list temperatures in Celsius, so it is vital to convert any Fahrenheit guidance you find online to Celsius to avoid pouring at the wrong temperature. Mixing the two units is a common mistake that leads to under- or over-pouring, which causes defects like frosting or sinkholes. Full details in our Candle Pouring Temperature Guide: Getting It Right First Time UK.

What happens if I pour the wax too hot?

Pouring wax too hot can cause frosting, sinkholes, and an uneven finish, regardless of how good the wax or fragrance might be on paper. High temperatures can also damage the container or jar, so getting the temperature right is essential for a professional look.

Do I need to buy a starter kit to get started?

A starter kit removes the guesswork by providing the exact wicks, jars and supplies that work well together, which is helpful if you are unsure where to begin. It is a convenient way to ensure you have everything you need without having to research compatible products individually.

Which wax gives the strongest scent throw?

Paraffin blends are the scent-throw champions because they have a higher oil-binding capacity than pure soy, making them ideal if you want a strong aroma. While soy is easier to use, a paraffin blend like Kerax 4105 (paid link) will give a noticeably stronger hot throw for fragrance-intensive projects.
