1. What happens if I heat the wax too much?

It depends on the type of wax. Soy: above 80–85°C it starts to degrade and gives off an unpleasant smell. Beeswax: above 85°C it darkens. Paraffin: above 90°C there’s a risk of cracking as it cools. Gel: above 95°C it loses its clarity. If you’ve gone over the temperature, let it come down naturally. Don’t try to pour straight away.

2. What happens if I pour too cold?

This is where most problems appear: soy – graininess, orange peel; coconut – matte surface; beeswax – streaks; gel – bubbles and cloudiness; paraffin – sandy texture; palm – incomplete crystals. Pouring correctly matters more than melting.

3. When do I add the fragrance so that it doesn’t separate?

The Servus rule is simple: the fragrance goes in between the melting temperature and the pouring temperature, within the window on the wax’s data sheet. Examples: soy container – 60–65°C; soy pillar – 65–70°C; coconut – at pouring, ~60–65°C; gel – 85–90°C, compatible fragrance only; palm – 88–90°C. Cold fragrance is the number one reason for separation.

4. How can I tell if the mould is too cold?

Clear signs: cracks on the sides, vertical streaks, visible layers, deformed figurines. The mould should be at 20–25°C, especially in winter. If in doubt, keep the mould close to the melters for 5–10 minutes.

5. Can I use the same thermometer for all waxes?

Yes, if: it’s digital or has a long probe; it hasn’t been used for food; it’s clean, with no traces of fragrance or oil. In the workshop we use a probe directly in the wax, not against the wall.

6. How do I avoid bubbles in figurines and gel?

Three rules: slow heating, pouring in a continuous stream, and the 5-minute settle before pouring. Gel loves calm. So do figurines.

7. What do I do if I poured too hot?

It depends on the defect: soy – central crater (you can remelt just the surface); paraffin – heavy shrinkage (top-up pour); palm – harsh crystals (it can’t be fixed, you can only redo it); coconut – edges pulling away (redo it completely); gel – loss of clarity (it can no longer be corrected). In most cases, the best solution is to redo the batch.

8. Why do I get a matte surface on soy and coconut?

Two causes: pouring cold and a cold container. The Servus solution: the containers warm up naturally next to the melters, never with a heat gun (it creates stresses).

9. Can I use the same set of temperatures all year round?

In theory, yes. In practice, no, because of the atmosphere. In winter we pour next to the melters. In summer we avoid draughts. The atmosphere is part of the recipe.

10. What is the most important Servus rule for temperatures?

Simple: slow melting. A 5-minute settle. Pouring at the right temperature. A steady atmosphere. If you stick to these four things, most defects disappear.

At what temperature does wax melt? Servus guide

In the workshop, the light always falls on the melters before it falls on the candles

Mornings in the workshop have a quiet of their own. Not an empty quiet, but one that breathes warmth, along with the metal and the soft steam rising slowly from the double-walled melters. Before the wicks, before the fragrances, before the moulds and the orders, everything starts here – in that zone of steady warmth that is the first thing to light up the workshop.

Those who come in for the first time see tables, tools, shelves.

Those who come a second time notice the order.

Those who come back a third time begin to feel the rhythm.

But those who work here every day know it well:

everything starts with the warmth of the melters.

I’m Sînziana, and this is the most complete temperature guide I’ve ever written

A guide built from years of real tests, not theory. Hundreds of batches poured in cold winters and scorching summers. Professional double-walled melters, with thermal oil and stepped control. Temperatures measured with a probe directly in the wax, not in the air, not on the wall. Candles repaired, corrected, repeated, sometimes late into the night. Stories from the workshop, from those evenings when you’re searching for the perfect temperature.

And, most importantly, the experience of the people who work here day after day. People who feel the wax in their hands before they measure it in degrees.

This is not a guide made by the internet.

It’s a guide made in the workshop.

1. The story of the Servus melters – the foundation of correct heating

1.1 How professional double-walled melters work

The Servus melters are designed for gentle, stable heating.

Here is the real mechanism, exactly:

The electric heating elements heat the outer wall.
The thermal oil between the walls takes up the heat and spreads it evenly.
The thermostat switches the heating elements on and off in fine steps.
The wax receives only indirect, steady heat.
The probe placed directly in the wax shows the real temperature, not approximations.

This is the foundation of Servus quality.

2. Room temperature – the secret variable of successful candles

Wax doesn’t work only with its own internal temperature, but also with the air around it.

This becomes extremely visible in the workshop, in winter as well as in summer.

2.1 Winter – the room is not artificially heated

In winter, the room is heated only by the melters.

The result is two zones:

The warm zone – next to the melters

stable pours
moulds and containers warm up gradually
the texture stays even

The cold zone – the rest of the room

moulds draw heat out of the wax
streaks, rough edges, cracks and graininess appear
thin figurines can give way even if the temperature of the wax is perfect

Differences of 2–3°C can change everything.

2.2 Summer – ventilation + air conditioning

In summer, the room is ventilated and air-conditioned.

The containers aren’t cold and the fragrance settles properly, but:

direct AC → a skin forms too early
air currents → uneven cooling
opening the doors → sudden changes

Summer needs attention too.

2.3 The Servus rule for the room

20–24°C in the pouring area
no draughts
moulds/containers acclimatise for 15–20 min next to the melter
in winter → we pour close to the melters

The atmosphere is part of the recipe.

3. A Servus secret – the 5-minute settle

Once the wax reaches the ideal temperature, I don’t pour straight away.

I leave it for 5 minutes to settle.

During this time:

the bubbles rise
the temperature evens out
the surface tension drops
the wax becomes calm

It’s technical, but it’s also a ritual.

Just as my grandmother used to say:

“Let it settle for a little while.”

4. The correct temperatures for each type of wax – as we use them in the workshop

4.1 Soy wax – container

A dial thermometer with a long probe, in °C and °F

melting: 70–75°C
fragrance: 60–65°C
pouring: 45–55°C

Specific defects

below 45°C → graininess, “orange peel”
too hot → crater, “wet” rings

Closing – The light you make with your own hands

Candles aren’t just wax and a wick. They’re moments. They’re feelings left in someone’s care. They’re quiet evenings, they’re memories that don’t yet know they’ll become memories. When you pour a candle, you put something into it that isn’t measured in degrees: you put in time, patience, attention.

When the wax melts in the double-walled melters, the story begins. When you let it settle for 5 minutes, you give it a soul. When you pour it with care, you give it shape. When someone lights it, you give it meaning.

If your candles turn out more beautiful after this guide, then a part of our workshop – warm, attentive, patient – has reached you. And for Servus, that’s all that matters.

If you work with several types of wax in the same batch

The right temperature is the first step. The second is the order in which you put the materials into the melter – especially when you work with blends or mixed recipes with two or three different waxes.

We wrote about this separately, from the same workshop:

Wax melting mistakes: why it takes 5 hours to melt a batch and how to choose the right order

The waxes we work with in the workshop

If you want to work with the same waxes that we test and use every day, you’ll find them here:
