The aim of this study was to investigate the influence of the indentation load, the period waste between indentation and measurement, and the gold coating on the fracture toughness (K-Ic) of a feldspatic porcelain (d.Sign, Ivoclar) measured by the Indentation Fracture Technique (IF). Porcelain beams (similar to3x4x20mm(3)) were fabricated by sintering green bodies at 870 C under vacuum with rapid heating and cooling rates. The samples presented microstructure composed of a glassy matrix, second phase particles and residual pores. Vickers hardness tester was used to produce indentation patterns on mirror polished surfaces. The diagonal of indentation (2a) and the length of crack (2c) were measured in an optical microscopy with better resolution than the hardness tester. The increase of indentation load from 0,2 to 5kg caused: i) increase of c/a ratio from 1,8 to 3,3; ii) almost no variation of Vickers hardness number; and iii) constancy of K-Ic value from 0,3kg load. It was observed no influence of a gold coating on K-Ic measurement. K-Ic suffered significant reduction with time, mainly in the first hour.
