I've been testing wicks with the Glass Glow, I've been using the CSN 14s for the most part but tried an LX wick just for fun. Not very good results (lots of tunnelling), so melted down and threw in an HTP 1212 just for fun. I'm using a 10 oz tumbler, 3" in diameter, Lemon fo from Nature's Garden at 1oz/lb. After the initial whopper of a flame settled down, I actually felt like I had a bigger and deeper melt pool than what I was getting with the CSNs. Anyone else been experimenting with HTP wicks? I may try the 126 just to see if that helps with the flame size.
