Abstract
The instant invention is related to the production of glass-ceramic articles which exhibit a hydrophobic character and an inherent tactile quality of being slippery or oily to the touch. Such articles are dervived from compositions within the MgO--Al.sub.2 O.sub.3 --SiO.sub.2 --F quaternary and contain the humite mineral norbergite (Mg.sub.2 SiO.sub.4. MgF.sub.2) as a major crystal phase. The intrinsic hydrophobic character and lubricity of the inventive compositions recommend their utility in such applications as (1) high temperature bearing or other low friction mechanical devices, an (2) non-sticking and easily-cleaned culinary ware.
