<strong>GC</strong> INITIAL PC<br />
Ideal for the fabrication of veneers, inlays and onlays using the<br />
pressing technique .<br />
› › Natural opacity<br />
› › Optimally cross-matched coefficient of thermal expansion<br />
› › Firing temperature of 950°C<br />
› › Suitable for staining and layering<br />
› › Identical shade system for layering<br />
› › High fracture and thermal stability<br />
› › Easy processing and robust stability<br />
› › Combines with <strong>GC</strong> Initial LF for a complete full ceramic<br />
system<br />
