I did two tests. One with straight pb and no FO and another one with the FO. Without the FO the candle looks good but not 100 % perfect. One or two roses break a little here and there. But by adding the FO, the wax turned too brittle and the candle didn't look good. So I added half soy container wax. But the container wax didn't make much of a difference. Now I am thinking of trying paraffin wax.
