Wow, yes, preventing sputtering on the glass seems to be the answer --
remembered I actually have some worn tubes that have heavy silvering only
on parts of glass where their anode meshes have small openings. Those anode
meshes really look like they do prevent sputtered cathodes to go through
Recently I got hold of a nixie tube without an anode mesh, and thought it
would be of your interest.
This tube, as seen in attached photos, completely lacks anode mesh in front
of digits. Instead it has an unusual, oblong, oval shaped anode *between*
cathodes, plus an upside-down 8 at about
*Hi, I’d like to share my project with you, a nixie tube kitchen timer.I am
really late coming into the nixie world -- I got my first nixie tubes last
year, just by a coincidence. I thought I wanted something that I can type
numbers into nixies, and decided to make a replacement for my
