I’ve been very pleased with the “Ti Pen”.

It is a titanium tipped pen that marks glass permanently. It actually leaves a titanium line on your glass that can withstand a full fuse without being “erased”.

The mark is very subtle (shows up better on darker glass). The pen is popular among lampworkers who need to make very small, subtle marks.
