I've even managed to cut holes for chains or split rings for necklaces with the Jasper by doing several passes & adjusting the focus each time. Interesting about the Cermark, I might try that with the spray over the weekend, it sort of makes sense though because I believe the Cermark is a ceramic based formular.
