What makes a candle dripless?

What makes a candle dripless is a special outer layer of wax. 
This layer has a higher melt point, and so does not melt as 
quickly as the center of the candle, forming a cup that holds 
the melted wax in. 

The American made taper candles we offer are made dripless by 
striking the perfect balance of wax formula and wick size. 
Under ideal conditions these candles will not drip. But as with 
any "dripless" candle, a draft or breeze could cause the flame 
or wick to lean to one side, which may collapse the "cup" that 
holds the wax in, causing the candle to drip. 

There are many things that factor in to how a candle burns.... 
running ceiling fans or central heat or air conditioning, cold-air 
return vent in a room, opening and closing doors in a room, 
an open window, humidity, anything that causes a draft, etc.

Another important factor in proper burning is wick trimming.
Wicks should be trimmed to 1/4" BEFORE burning and will also 
require trimming during burning. This is true for ALL candles.  
Candles should never be burned unattended, so check the wick 
often to see that they burning properly.  

Wicks on taper candles will bend over as they burn. Don't allow 
the  wick to get so long that it bends over and touches to top 
of the candle, forming a "loop".  If the wicks get too long the 
candle burns faster than it should and this is what causing 
dripping and smoke.  The flame of a taper should stand about 
1.5" tall and should NOT flicker.  If it flickers and is fighting 
to stay lit the candle is in a draft and will burn too quick.  

Drafts and not trimming wicks are the main causes of dripping and smoke.

ALL candles require attention and maintenance during burning.

Please follow these guidelines for maximum burntime and enjoyment!
