If the bottom of the candle has an airtight seal, it produces that residue. A above water, B in the water, E in the ear.

Andrew Harter took over the design and implementation of the test. A student of his volunteered to be the subject. The results are shown here. The candle stubs have been cut open and spread to examine the inner surfaces. First, look at specimen E1. This came from the first of three candles burned in the one ear. There is a quantity of very fine beige-colored dust/ash that has formed a fragile, porous structure not unlike cigarette ash in consistency but somewhat lighter in weight and strength. Specimen E2 is very similar. But E3 has a decided difference; at the places indicated by the X pointers, we found very serious gobs of a sticky, waxy, dark brown substance. To all of us, this certainly resembled ear-wax! At points indicated by the Y pointers, we saw very slight, somewhat lighter-colored, traces of a waxy deposit. Hmmm!
Had the experiment gone just this far, we might have concluded that there is merit in the ear-candling procedure. But Andrew was intent on conducting control tests, too. By that, we mean doing the same test without the ear being involved. He placed a candle, properly seated in the paper shield, over a glass with some water in it. The candle burned down just as before, but as you will see on specimen A, no deposit of any kind was produced, no beige-colored "ash," nor any brown waxy substance. But now I will reveal to you a fact that may provide you with an important clue: the candles were impregnated with bees-wax, not candle-wax nor paraffin wax! (British readers, note: in the USA we use the word "paraffin" to describe a translucent white wax, while you use that word for what we call "kerosene." Isn’t cultural exchange wonderful?)
Bees-wax varies in color from amber to brownish. When charred, it turns quite dark brown, the color of the globules we found at position X in our illustration. But what about specimen B? Well, that was obtained when Andrew burned another candle over water, but this time inserted the tapered end into the water, sealing it off. The B specimen cannot be differentiated from E3! Now, there is a small deposit indicated by the Y pointers on all specimens except A. We believe that specimen A, having clear access to air drawn in from the bottom by convection, attained complete combustion, and thus consumed all the wax and fabric. Specimen B, cut off from free air access as were the three E specimens, produced gobs of beeswax and some ash. E1 and E2 did not produce wax globules because the "fit" was not as tight; warmed ears can produce a film of naturally-present wax that will provide the seal, and the subject is perhaps more willing to have the tube stuck into his ear further and tighter, and less afraid of getting an ear-canal full of hot bees-wax — not a nice thing to contemplate. Thus the combustion in a sealed-off tube is less efficient, and the brown bees-wax globules are produced.
