These concrete candles are made using part used pillar candles and homemade moulds. They are a great way of trying out candle making without spending a load of money on equipment.

What can you use as a homemade candle mould?


There are three things to consider when choosing a homemade mould for candle making. Firstly, is the frame strong enough to support the weight of the wax without collapsing? Secondly, can it cope with the heat of the melted wax? And finally, will you be able to remove your finished candle from its mould without damaging it.


I use cardboard tubes and plastic bottles for my homemade moulds. All these items are robust enough to hold the hot wax safely but easy enough to tear open to remove my finished candles without damaging them.

Reusing old candles


It is worth saving up part used and broken candles as they can all be melted down and reused to make new candles. Different types of candles do use different wax mixes so keep the wax from pillar candles and jar candles separate. You can also reuse coloured and scented candles.


Group complementary scents and colours and mix in with plain candles to make you own bespoke wax mix. Add coloured wax crayons to melted wax as a frugal way of colouring candles.


Melting down store-bought pillar candles will provide you with the perfect wax mix to use in homemade moulds. Once melted, you can remove the wick and reuse it for a new project.

How to make concrete candles.


Select your moulds and cut them down to size to make it easier to add the cement and wax. They need to be at least 1inch taller than where you plan to fill to make it easier to remove the mould once the candles have set.

Mix up the quick-set cement and spoon a layer into the bottom of each of the moulds. I angled two of mine and left the rest flat.


Leave the cement bases to set overnight.

Melt the old pillar candles in a double boiler or a bowl over a pan of simmering water. Wax ignites very quickly, so should not be left unattended while melting and is not safe to melt in a microwave.

Once melted, fish out the old wicks to reuse, add scent if using and pour into the prepared candle moulds on top of the cement.


I use a piece of card to hold my wicks straight while I wait for the wax to harden.

Topping off candles.


As candles harden in their moulds, it is common for the centre to sink, leaving a crater around the wick. One way to minimise this flaw is to use a second pour to ‘top off the candle’.


Once the concrete candles have cooled and set for a couple of hours, use a wooden skewer to make 4 or 5 holes around the wick as shown in the photo. Pour the second layer of wax to fill up the gaps and the crater and then leave the candle to harden overnight.

Removing the concrete candles from their homemade moulds.


To remove the concrete candles from their homemade moulds make cuts down from the top towards the candles. Carefully tear the sides away, exposing the candle.

    Great project! Can you add color to the cement to make different color bases? If so, what would you use to change the cement color?

    • Powdered tints for sure they, the online places like Ebay or Amazon have lots of different cement tints to try n use some I've bought were gr8 for pavers going into the garden n making critter molds like squirrels etc... fun.

    Why concrete? Just use another wax color

      Not only does the cement add a more industrial look, it actually makes the candle look taller. This is a perfect way to use up leftover cement from another project. It's also a fine way to put a more contemporary look to an old Christmas candle that was more interesting to the giver than to the recipient. ;)

    How can you tell which used or new candles WAX does not throw off black suit Or burns clean?

      Keep the wicks trimmed to 1/2”. Store bought wax and candles are very reliable. And never leave lit candles alone. It’s better to set candles on a glass or metal tray and keep all flammables away from them, including ribbons, bows, greenery, polyester flowers, and paper glitter. Seven weeks to Winter! Jewell

    I think this is a great idea. I have made these with plaster, but the cement should be a little safer. It’s easier to add vegetable colors because plaster is white. Thanks for a quality tutorial. Best wishes, JJewell
