I know this is an old thread, but I have been trying to wick the 8oz sq. mason and it is giving me a fit! I was at Candle Science today and they told me to doublewick it diagonally corner to corner. We will see what happens. When I was trying to single wick it would either smoke, large flame, huge mushrooms or the flame would dance around like crazy! This one is a booger! BTW I use ecosoya CB135.
