The principle of our concrete fire is to recycle or add candle residues and thus provide wax. If the concrete fire is repeatedly fed with wax, the wick can continue to draw liquid wax and only burns this. We recommend not to let the wick protrude more than 2cm from the wax. This is the only way to ensure that it can then draw in enough liquid wax.

Most of our fires are about two-thirds filled with wax. This offers the great advantage of long-lasting enjoyment of our products. However, we recommend keeping the wax level of your concrete fire fairly constant in the upper range. This is the only way to ensure that our unique refillable garden light will provide you with light for many years to come. However, if you fail to add wax in good time, the tip of our biological permanent wick is in danger of losing material (due to the low wax level). However, the concrete fire can still be used thanks to the generous filling with paraffin. The flame just sinks a little deeper into the concrete bowl.

In principle, all common types of wax (e.g. paraffin, stearin, beeswax) can be used to fill our Betonfeuer. In contrast to comparable products, our organic permanent wick does not clog. In addition to the type of wax, the color of the candle remains is also irrelevant. Whether you add red, yellow or white candles to your wax fire is entirely up to your taste. Since our concrete vessels are compacted during the production process, there is also no risk of a wax-sucking effect. The concrete fire will therefore not take on the colour of the candle remains used.

Not only the design of our products is kept puristic and simple! The handling is the same. Candle remains, tea lights or our wax supplies are simply added to the fire as a whole. As the name of our creations already suggests, the flame in our Betonfeuer is a rather larger flame comparable to a small cozy campfire. This is therefore strong enough to melt the wax for you.
All you have to do is sit back and enjoy. Have fun!

Wicks do not necessarily have to be removed before adding. Since our Betonfeuer product line impresses with its simplicity in all areas, such a laborious step is not intended. However, the wicks and any other impurities in the combustion chamber should be removed quickly. Otherwise, these could also catch fire and thus create a larger flame.

Our tip: Add your wax leftovers to the combustion chamber as a whole. As soon as the wax has melted, the wick can be easily removed from the concrete fire using a non-flammable object.

If less wax is added than recommended, the wick will also be affected. Your concrete fire can only be used for many years if the wick always has enough liquid wax available, which it can easily pull up. We recommend that the wick should not protrude more than 2 cm from the wax. This is the only way to ensure that the flame burns through liquid wax and not through the wick. If the wax level drops so much that no more liquid wax arrives at the tip of the wick, the wick itself will also smolder.

The outer skin of a Betonfeuer usually does not get particularly warm. However, this has a lot to do with the way it is operated. If the flame is very deep in the pot, the sides can get hot. However, the floor of our Betonfeuer remains quite cold due to the solid concrete base. You can therefore use your fire on a table etc. without any problems. However, since the flame of such a refillable wax fire can get very hot, the general rules for handling candles must be followed.
