I am burning now a 10 oz apoth jar and used 2 csn 11's in them. They are burning great, no hangup, no soot, good flame. In my 10 oz tumblers I used the csn 14 and it burned good. As far as pillars go - a 3" pillar is burning great with the 11 csn wick. It has a good "shell" around it. Real pretty:highfive:
