Title: Glaze reversibly changing colour with temp. variations - for use as continuous temp indicator or for decorative purposes
Inventor: SPAETHLING WALTER
IPC: C03C8/14
Filed: 1974-10-29
Abstract: Glaze changing its colour with temp. variation consists of 60-99 wt.% (pref. 90-99 wt.%) of a glass frit, the remainder being a colouring agent contg. elemental S and/or Se and/or Te and/or metal sulphides and/or selenides and/or tellurides, and/or metal chromates.
