Thanks for the reply Steve and mzphee! My thought process behind adding the 4625 was to increase my burn time a little, rather than add something like vybar or stearic and risk locking my fragrance. Adding it did do that, but also decreased my HT, still better than some I've tried, but not as good as the straight 6006. I have to agree, it wasn't really broken. I currently use the CD wicks and they work great, just not impressed with the behavior of this wick, with the scents I like. I really like the LX as it's not a mushroomer for me. I'm not using a high fragrance load(1:1) so I'm at a loss as to what the mushrooming is coming from, a CD 60 in a 2 1/2 diameter tin, should be perfectly fine. I also wanted to come up with something that would pop out of a warmer easily, as you know 6006 isn't coming out without a fight! lol No one complains, because the throw is worth it, but I'd like my customers to not have to "work" at changing scents in the warmer. I guess I need to change over to a straight paraffin for my tarts or head back to the drawing board. Unless either of you have suggestions for me to test out? Thank you so much for all the insight you give in this forum! It's great to have a source of knowledge to draw from on this journey!
