GC Initial LiSi is a specialized veneering ceramic designed for lithium disilicate frameworks. Thanks to the exact cross-matched coefficients of thermal expansion (CTE), its low firing temperature and high stability during multiple firings, GC Initial LiSi ensures you safe and predictable processing of lithium disilicate frameworks. GC Initial LiSi can be used in the individual layering and in the cut-back technique following the proven Initial ceramic concept; one shade system; one layering technique. Shade Medium Translucency B0, 5pcs 3g ingots.
