Cerardor / CeraFlare
Are there candles that burn soot-free?
The soot-free burning of candles only works under rather unrealistic conditions of weightlessness in space. Unfortunately only a blue spherical flame develops. The bright yellow light so familiar to us is missing.
The bright glow of candles is only created because the smallest soot particles are heated so much in the flame that they begin to glow. Without glowing particles in the candle flame there is now bright light to enjoy. Soot free candles would rather be pointless for our needs.
For how long will the wick last?
The glass fibre wick does not burn and theoretically has an unlimited life.
Why a replacement wick is nevertheless occasionally required is explained below:
Cerardor and CeraFlare only burn wax. The best firing results are achieved with pure paraffin wax. Through the use of candle residues, however, wax admixtures are also enriched in the melting pot whose properties can have a negative effect on the burning behaviour of the glass fibre wick.
It is known that
bees wax will bring the function of the glas fibre wick to a standstill.
The calillary in the wick sticks together and therefore no more wax can be transported to the flame.
black candles, soot particles are added to the wax for colouring. The soot particles accumulate on the wick and form a "barrier". The barrier prevents the flow of wax. We can only burn wax - no soot.
Can lamp oil or bioethanol be used as fuel?
CeraFlare are purpose build for use of candle wax only.
The use of other fuels could cause dangerous over heating.
For use of bioethanol
EldoFlare is the best choise!
What to do when water has run into the melting pot?
It depends on the condition of the melting pot at the time water has run into the pot:
the wax depot is solidified and hard
Try to pull the wax block out of the melting pot by the wick.
Then you can simply pour off the water. Afterwards the wax block is put back into the
the wax depot is liquid
Liquid wax is hot and is not "compatible" with water. The melting pot should immediately
be covered with the extinguishing lid. Then it means waiting! Only when the wax depot
has solidified and become hard again, proceed as described under (a)
It happens that small amounts of water remain trapped in the wick. When the burner is restarted, a crackling noice is heard. It stops again after some time. Then the trapped water droplets are evaporated.
How to clean the glass cylinder?
Soot deposits are most easily wiped off with a dry paper towel from the kitchen roll.
Wax is removed with hot water. Please do not scrape off with sharp-edget objects.
What does the air temperatur have to do with the function of the burner?
Energy is required to melt the wax depot. The energy required for this is obtained from the burning wax. Excess heat energy is released from the melting pot into the ambient air.
When temperatures fall, more energy is dissipated to the cooler ambient air. Then less energy is available for the melting process .
The function of the burner is based on an
exessive energy balance. This means that the burner releases more energy than is needed for the melting process. However, a
negative energy balance can arise when temperatures fall. Then more energy is dissipated to the environment. Under certain circumstances, the amount of heat released is no longer sufficient to maintain the melting process.
Are there starting aids to light the burner?
Cerardor is often confused with a candle. One holds a lighter or match to the wick and expects the flame to ignite - like a candle.
However, the wick in the melting pot does not work like the wool thread in a candle. Because with the melter, physics must first take over and start the melting process. Only when enough heat has been generated and enough wax has liquified can the typical flame pattern of
CeraFlare be created.
Tips for starting assistance are listed in the operating instructions. This can be downloaded as a PDF document in the download area.

Can all remains of candles be used?
No! Bees wax and black candles are not suitable.
For more informationen check the question "How long will the wick last".
Must the woolen wick be removed before recycling?
No! During the melting process, the wool threads detach from the candles and sink to the bottom of the melting pot. When the wax depot is completely liquified, the wool threads can be removed from the melting pot with a food fork or similar tools.
Can the wick be replaced?
Yes. It´s quite easy to change the wick.
There are two ways to chenge the wick.
Emptying for cleaning purposes:
.... by burning the wax from the melting pot down to the heating sleeve.
Then the filling is burnt down to a residual amount of about 2 cm.
Now the flame is extinguished and the wick is pulled out of the heating spiral.
The remains in the melting pot containes wick threads, glitter and other impurities from the recycled candles. This residual quantity is disposed of completely.
Now a new wick can be drawin into the heating spiral and returned to the (empty) melting pot. Only then wax (or remains of candles) is filled in again, which is liquified in the water bath. Take another teaspoon and trickle liquid wax over the wick. Now let the water bath cool down and remove the melting pot with the new wick.
Changing the wick without emptying the melting pot:
To do this, place the melting pot in a water bath to liquefy the wax supply. When the wax is completely melted, remove the heating coil and pull out the wick. Now e new wick can be drawin into the heating spiral and then inserted again in the still liquid wax. Now the wick tip must be sprinkled with wax. Afterwards the water bath can cool down and the melting pot can be taken out.
Can I order a wick as a spare part?
Yes! All our products ar build for replacebility of individual components which can be ordered as spare parts.
Stainless steel bowls
Are the stainless steel bowls waterproof?
Yes, the are no drainage holes.
In case of outdoor use a drainage hole can sometimes be useful.
Users can drill drainage holes for removal of excessiv water if desired.
What is the use of a suppot ring?
The support ring can be a usefull addition to the bowl Ardor. This support ring is used for sand, earth or gravel fillings of the outer space of the bowl. It keeps the centre of the bowl free for other decoartive elements such like a vase or lanterns.
What is the heating value of bioethanol?
The heating value of bioethanol is 7,4 kWh/kg. This is about 2/3 of the value of fuel oil with 11.8 kWh/kg. (Data from Wikipedia)
