12 Candle Making Mistakes Every Beginner Makes (and How to Fix Them)

So you've decided to start making candles at home — exciting! But if your first few batches haven't turned out the way you imagined (uneven tops, weak scent, tunneling wax, or a wick that won't stay lit), you're not alone. These are some of the most common candle making problems every new chandler runs into, and the good news is that almost all of them are completely fixable.

As we covered in our guide to the best candle making kits for beginners, having the right supplies matters — but so does knowing how to use them correctly. Many beginner candle mistakes come down to a handful of easily avoided errors: the wrong wick, the wrong temperature, or skipping a step that seems minor but isn't.

In this post, we're walking through 12 of the most common candle making problems beginners face, explaining exactly why each one happens, and giving you a clear, actionable fix. Whether you're troubleshooting a candle you already made or want to get it right the first time, these candle making tips will save you a lot of wasted wax — and frustration.

Frequently asked questions

Why does my candle have a hole in the middle?+

This is called tunneling, and it's usually caused by burning the candle for too short a time on the first use, or using a wick that's too small for the container diameter. The wax develops a 'memory' after the first burn — if the melt pool doesn't reach the edges, it will continue to tunnel on every subsequent burn. See our full guide at /blog/candle-tunneling-fix for detailed solutions.

Why does my candle not smell strong enough?+

Weak scent throw is usually caused by adding fragrance oil at the wrong temperature, not using enough fragrance oil (aim for 6–10% of the wax weight), or using a low-quality fragrance oil. Make sure you're adding fragrance between 180–185°F for soy wax and stirring slowly for at least 2 minutes to fully incorporate it.

Why does my soy candle have a white, chalky coating?+

That white coating is called frosting, and it's a natural characteristic of pure soy wax. It doesn't affect burn quality or scent throw. It's caused by the natural polymorphic nature of soy wax recrystallizing over time. You can minimize it by pouring at a slightly higher temperature and keeping candles away from drafts while cooling.

Why does my candle have wet-looking spots on the glass?+

These are called wet spots — they're actually air pockets between the wax and the glass caused by the wax shrinking as it cools and pulling away from the container. They don't affect performance. Pouring at a slightly higher temperature and warming your containers before pouring can reduce them. Check out /blog/how-to-fix-wet-spots-on-candles for more tips.

Can I use any fragrance oil for candle making?+

Not all fragrance oils are safe or effective for candle making. You need fragrance oils specifically formulated for candles — ideally phthalate-free and rated for candle use. A set like the P&J Trading Fragrance Oil Set (Top 6 Candle Scents) is a good starting point because it's premium grade and phthalate-free, making it safe for candle making, soap, and bath bombs.

What is the best wax for beginner candle makers?+

Soy wax is widely recommended for beginners because it's easy to work with, burns cleanly, and holds fragrance well. A 100% natural soy wax like CandleScience All Natural Soy Candle Wax (464 formula) in flake form is especially beginner-friendly because it melts evenly and is easy to measure and pour into containers.
