ABSTRACT:
A chemically-machinable glass-magnet composition comprising a photosensitive chemically machinable glass having a magnetic material in admit therewith, wherein the photosensitive chemically machinable glass is formed of SiO.sub.2 --Li.sub.2 O--Al.sub.2 O.sub.3 containing photosensitive materials selected from silver, gold and copper and a cerium dioxide sensitizer; and the magnetic material is a Ni-Cu-Zn ferrite.
