Been using a alcohol burner for many years and I think you are over heating your heads. On a 1/32 I give a count of 1000-1 flip 1000-2 dip the head and on 1/16 a count of 1000-1 flip 1000-2 flip 1000-3 flip 1000-4 dip. Chartreuse is very heat sensitive and I only do a count of 3 for the heating process.
