“Look at how a single candle can both defy and define the darkness.” 
― Anne Frank

For centuries, candle-makers, or chandlers as they were known, were tasked with bringing light, warmth, and comfort to the cold, dark nights.

The Science Of Candle Craft

For much of  history, candles were a valuable commodity only the wealthiest could afford.  As a result, the chandlers' skills were highly sought after.  Over time, their innovations harnessed new ingredients and techniques to create affordable, clean-burning, and long-lasting candles for the masses as well.

Today, the art of candle-making is a multi billion dollar industry and candles are seen as a luxury instead of a necessity.  yet, while technology has found faster and cheaper ways to produce them, something has been lost - the pride, careful attention to detail, and thoughtful touches of the craftsmen of the past.

At Jiva, we are bringing simplicity back into the art of candle craft.  As both retailers and manufacturers, we understand the importance of a quality candle.  We offer a wide range of premium and luxury candles and we also teach candle crafting classes! We offer lessons to individuals or groups and are available for mobile or onsite parties.  Whether a seasoned chandler or a budding enthusiast, we have the class for you!

Do you ever wonder why a candle flame points up?

When a candle burns, the flame heats the nearby air and starts to rise. As this warm air moves up, cooler air and oxygen rush in at the bottom of the flame to replace it.

When that cooler air is heated, it too rises up and is replaced by cooler air at the base of the flame.

This creates a continual cycle of upward moving air around the flame (a convection current), which gives the flame its elongated or teardrop shape.

Because “up” and “down” are a function of the earth’s gravity, scientists wondered what a candle flame would look like in outer space, where the pull of gravity is minimal and there really isn’t an up or down.

 

Do you ever wonder why there are different colors in a candle flame?

If you look closely at a candle flame, you’ll see a blue area at the base of the flame. Above that is a small dark orange-brown section, and above that is the large yellow region that we associate with candle flames.

The oxygen-rich blue zone is where the hydrocarbon molecules vaporize and start to break apart into hydrogen and carbon atoms. The hydrogen is the first to separate here and reacts with the oxygen to form water vapor. Some of the carbon burns here to form carbon dioxide.

The dark or orange/brown region has relatively little oxygen. This is where the various forms of carbon continue to break down and small, hardened carbon particles start to form.

As they rise, along with the water vapor and carbon dioxide created in the blue zone, they are heated to approximately 1000 degrees Centigrade.

At the bottom of the yellow zone, the formation of the carbon (soot) particles increases. As they rise, they continue to heat until they ignite to incandescence and emit the full spectrum of visible light. Because the yellow portion of the spectrum is the most dominant when the carbon ignites, the human eye perceives the flame as yellowish. When the soot particles oxidate near the top of the flame’s yellow region, the temperature is approximately 1200o C.

The fourth zone of the candle (sometimes call the veil) is the faint outside blue edge that extends from the blue zone at the base of the flame and up the sides of the flame cone. It is blue because it directly meets with the oxygen of the air, and is the hottest part of the flame, typically reaching 1400o C (2552o F).
