There is something deeply calming about melting wax, centering a wick, and waiting for it to solidify — it is, at the same time, simple chemistry and a bit of everyday magic.

Candle making is one of the most accessible craft skills you can learn at home. You don’t need industrial equipment or years of practice — you need curiosity, a few well-chosen materials, and the willingness to experiment.

For many, the process starts as a therapeutic weekend activity and slowly turns into a small creative business. Handmade candles are among the most sought-after products, and the market continues to grow. But whether you want to sell or just create, the foundation is the same: understanding the materials you work with.

In this guide, we explain step by step everything you need to know — how to make candles from scratch — focusing on the three fundamental elements: wax, wick, and fragrance.

Wax — the heart of the candle

Wax is the material that defines a candle’s character: how it looks, how it burns, how it holds fragrance, and its environmental impact. Choosing the type of wax is the first and most important decision you will make as a maker.

In today’s market, two types dominate: soy wax and paraffin wax. Each has its own strengths and limitations.

Quick comparison

Which one should you choose?

If you want to build an artisanal brand with a sustainable message and clean design, soy wax is the natural choice. Soy candles in glass jars have that “slow living” aesthetic that customers appreciate and actively seek.

If your priority is fragrance intensity — for example, for pillar candles or customers who want strong scent diffusion in large spaces — paraffin wax or a soy-paraffin blend can be a valid option.

The wick — the engine of the candle

Of all the candle supplies you need, the wick is the most underestimated and, at the same time, the most critical. The wrong wick can turn a beautiful candle into a product that doesn’t perform properly — regardless of the quality of the wax or fragrance.

The two extremes you must avoid

• Wick too small: The candle “tunnels” — it melts only in the center, leaving thick walls of unmelted wax on the edges. The result is major material waste and weak scent throw.
• Wick too large: The flame becomes too high, produces smoke and soot, and may overheat the container. It is also a safety risk.

How to choose the correct diameter

Basic rule: the container diameter determines the wick size. Candle accessory manufacturers provide guideline charts, but testing remains essential because the type of wax and fragrance load also influence wick performance.

• Containers up to 5–6 cm diameter — small wicks
• Containers between 6–9 cm — medium wicks (most common)
• Containers over 9 cm — large wicks or double-wick setup

Testing protocol (simple and effective)

1. 1
   First burn

   Burn the candle until the melted wax reaches the edges of the container (full melt pool). It should take about 1 hour for every 2–3 cm of diameter.
2. 2
   Check flame height

   A healthy flame is 1–2 cm tall, burns steadily, and does not produce smoke. If the flame flickers excessively or produces black smoke, the wick is too large.
3. 3
   Trim the wick before each burn

   Keep the wick at a maximum of 5–6 mm above the wax. A wick that is too long is the main cause of high flames and smoke.
4. 4
   Take notes

   Keep a testing journal with wax type, wick size, fragrance percentage, and results. It’s the best long-term learning tool.

Fragrance — the olfactory balance

Fragrance is the reason many people choose an artisan candle over an industrial one. It’s the emotional element — the one that creates a memory. That’s why how you add fragrance to the wax matters just as much as the type of fragrance you choose.

Temperature — the most overlooked factor

The most common mistake beginners make is adding fragrance at the wrong temperature. The wax temperature at the moment of mixing determines how well the fragrance binds to the wax molecules — and therefore how strong the candle will smell when burning.

The golden range for soy wax is generally between 65 and 75°C. At this temperature, the wax is still liquid and fluid, but cool enough not to burn or evaporate fragrance compounds. Stir slowly and evenly for 1–2 minutes for proper dispersion.

Recommended fragrance load

• Soy wax: 6–10% of wax weight (e.g., 80g fragrance per 1kg wax)
• Paraffin wax: 8–12%, as its molecular structure allows a higher load
• Do not exceed recommended levels — excess fragrance won’t bind and may cause burning issues

Curing — patience that makes the difference

After pouring, let the candle “rest” for at least 48 hours before the first burn and fragrance evaluation. The curing process allows the wax and fragrance to fully bind. Many scents seem weak immediately after pouring and become much stronger after 3–5 days.

First steps: start small, learn a lot

Candle making is a science intertwined with art. It has rules — temperatures, ratios, diameters — but also a huge space for interpretation, personal taste, and storytelling. There is no universal recipe, and that’s exactly what makes it fascinating.

If you’re just starting out, we recommend resisting the temptation to buy ten types of wax and twenty fragrances in your first week. Instead:

• Choose one type of wax and learn it well
• Test 2–3 wick sizes for your chosen containers
• Work with one fragrance per session and document everything
• Burn each test candle completely and analyze its behavior
• Accept that your first 10–20 candles are part of the learning process, not failures

Every experienced maker has had a first tunneling candle, an oversized wick, or a fragrance that didn’t bind properly. The difference between a beginner and an experienced maker is not perfection — it’s the number of iterations.

Start. Melt. Pour. Learn.
