I bought this wick to use with 444 soy wax. burns slow with even flame but not much of a warm throw. I used 1.4 oz (weighted) fragrance oil for 1 lb of 444 soy wax. This wick curled and caused not even pooling. I got HTP 104 6" for a 2.75" - 3" diameter jar, and it would work fine if it didn't curl.
