4x4 apothecary wick help please

[Old Crab]

Hello - and Happy New Year all.

I have been trying my best to wick a new jar (for me?).

It is the 4" x 4" apothecary.

Wax = igi 4627

1oz FO

Liquid dyes

I realize that I can not single wick the jar so I have been double wicking it.

So far I have tried

Cd 12

Cd 14

Cd 16

All the candles burn well at the beginning, and as long as I stop the burn at 4 hours very very minor soot. The candles will typically reach a decent and complete melt pool in around 2 hours.

The issue starts when the jar is around half full the wicks are barely a 1/4" tall and have small flames. After burning for 6 or even 8 hours the candle melt pool will not be near the glass - sometimes distant by 1/4" to 1/2".

The other jar I use is only 3 3/4 wide and I double wicked it with cd16 which I think are too big - same formula and never had this issue.

I think I should go up to a cd 18 but hard to believe two cd 18 are necessary.

I've tried using zinc, htp, and LX wicks but I and others have noticed the scent throw is stronger with the cd.

I would appreciate your thoughts.

Thank you.
