I'm Moving From Kitchen-Scale Candle Making to 10 Kg Batches — What Process Variables Become More Important When the Wax Volume Increases?

Why the kitchen method stops being enough

At 500 g or 1 kg, you can melt wax in a double boiler, add oil, stir with a spoon and pour into a handful of jars within a quarter of an hour. Temperatures swing, but they swing quickly past the point where it matters. The wax is poured before it has time to wander. Most variables are controlled simply because there is no time for them to go wrong.

At 10 kg, that protection disappears. The wax is heavier, deeper and slower in every sense. It takes longer to melt, longer to cool to the addition temperature, longer to stir and much longer to pour. Each of those longer periods is a window in which something can drift. The variables below are the ones that move from 'handled automatically' to 'needs an owner'.

Variable one: how much liquid your vessel really holds

This is the one almost nobody checks until the first batch. Wax is sold by weight; vessels hold volume. Melted soy wax is roughly 0.9 g per ml, a general approximation rather than a figure for any particular wax. On that basis, 10 kg of liquid soy wax occupies about 11 litres (10,000 g ÷ 0.9 ≈ 11,100 ml).

CSI's Electric Wax Melter (Imported) is sold in a 10 kg capacity, and its product page states that it melts 9.5 litres of wax at a time. Again using the rough 0.9 g per ml, 9.5 litres is about 8.5 kg of liquid wax (9,500 × 0.9 ≈ 8,550 g). The same page also states it melts 10 kg of soy wax in approximately 30 minutes at 100°C. These figures do not sit neatly together, which is exactly why you should measure your own working fill rather than plan on the headline number.

The page also mentions making 80 candles at a time. That figure does not state a candle size. At 200 g, 80 candles would need 16 kg of wax, so it clearly refers to smaller candles. For 200 g jars, plan from the liquid volume instead: roughly 8.5 kg is about 42 candles, before wastage.

Variables two and three: true temperature and hold time

In a small pot the thermometer reading and the pot's contents are close to the same thing. In a 10 kg vessel, wax near the heating surface, at the centre and at the top can differ, particularly before a stir. The melter's own display, which CSI states has a ±10°C deviation across its 60°C–100°C range, reports one number for all of it. Read the wax directly with a separate thermometer, after stirring, with the probe in the body of the wax.

Hold time is new at this size. A kitchen batch is scented and poured within minutes. A 10 kg batch can sit scented for a long time while jars are filled one pitcher at a time. Record the clock time when oil goes in and when the last jar is poured. If your candles vary from first to last, this number is usually part of the explanation.

Variables four to six: stirring, pouring and power

Stirring reach

A spoon reaches every part of a 1 kg jug. In a deep 10 kg vessel you need a stirring tool long enough to sweep the base with your hand well clear of the wax, and a routine that includes the walls. CSI does not sell long mixing paddles, so if you buy one, choose something smooth, heat-resistant and easy to clean between fragrances.

Pouring trips

Kitchen batches are often poured straight from the pot. From a melter you pour into a pitcher and then into jars, over and over. CSI's large steel pitcher holds 600 ml, so a 10 kg session means many trips. Each trip cools slightly in the pitcher, and the batch waits between trips. Count the trips and log the pour temperature at the first and last jar.

Workspace and jars

Five jars fit beside a kitchen stove. Fifty need a bench, set out and wicked before the wax is ready, in a place where they will not be moved while setting. The room itself becomes a variable: jars on a cool bench near an open window set differently from jars in a still, warm corner. Note where each tray sat, and keep the layout the same from batch to batch so that differences in surface or adhesion can be traced to something real.

Electrical load

A 1-litre Mini Electric Wax/Soap Melter runs on 300 W or 600 W and plugs in like a kitchen appliance. A large melter can draw considerably more, and CSI does not publish that figure in the product details we hold. Read the power rating on your unit's label, avoid extension boards and multi-plugs, and ask an electrician to confirm that the socket and circuit can carry it for a full production session.

What to keep from your kitchen setup

Do not throw out your small equipment. Fragrance trials, wick tests and new formula tests still belong at 500 g to 1 kg, where mistakes are cheap and results arrive quickly. A 1-litre mini melter at ₹2,360.00 is well suited to that job, with dual 300 W and 600 W modes and a stainless steel liner. One reviewer, Tanya Walia, wrote: “It has made my candle making journey so much easier.” Another, Priya Singh, wrote: “Plz launch same product in 2-3 litre also”, which captures the gap many makers feel between 1 litre and 10 kg.

The goal of this transition is not more equipment. It is knowing, for every 10 kg batch, what the wax actually did. Once those numbers are on paper, you can decide from evidence whether the next purchase is a second melter, a larger pitcher, or nothing at all.

CSI already has guides that cover parts of this question. This page takes the production-floor angle; these go deeper on the rest:
