Abstract
The invention relates to glass-ceramics. It concerns a process to obtain sensibly colorless transparent glass-ceramics from a glass-ceramic composition containing more than 0.50 weight % titanium dioxide and possibly iron oxide, that would normally provide colored glass-ceramics; this process is characterized by incorporating into the said composition an appropriate proportion of neodymium oxide so as to make the glass-ceramic sensibly colorless. Application to the manufacture of diverse articles.
