What is wick Yield?

Follow

People often get confused about what the 'yield' of a wick is.  

As we know, a candle wick is made up of many smaller cotton strands, sometimes with additional support threads made of cotton, paper, linen or even metal.  All of these elements have weight and yield is a measure of this weight.

Wick Yield is simply the number of metres of raw (unwaxed) wick per kg.

Let's take a look at two examples as below:

LX10 - Yield = 1363 m/kg

LX22 - Yield = 655 m/kg

So, in the case of the LX10, if you took a 1kg spool of unwaxed wick and unwound it, it would be approximately 1363 metres long.  If you did the same with the LX22 wick, it would only extend 655m.  So, an LX22 is roughly twice as heavy per metre as an LX10.

So, the smaller the yield, the more material there is in a metre of wick.  An LX22 is therefore much heavier than an LX10.

Although weight is not the only factor that influences how a wick will perform in a given blend, it is a pretty good indicator of power.  It is particularly useful for comparing wicks from different families, i.e. how does a Stabilo 10 compare to a CL10 or a V10?

Attached is a sheet that shows the yield for all of the wicks we sell.  To aid understanding, we have added a column that shows the approximate weight of raw wick per metre.  The smallest is a V4 wick, weighing just 0.5g per metre.  The heaviest is a VRL26, coming in at over 3g per metre (6 times heavier).
