Oh wait...did you say you are using frit? What kind of frit? Because many of them will pit when marvered. You just have to experiment and see which ones do that and which ones won't. Been my experience for years, so that's why I won't let beads with frit touch a graphite marver. You would have less problems with brass presses, but some glass frits will still pit. Like the violet purples, blues, and turquoise (copper blue) colors.
