“…In previous papers, the sinter-crystallization of a glaze almost entirely made up of an anorthoclase-devitrifying strontium frit was studied, it is verified that, when frit particle size was smaller than 1 µm (particle size used for inkjet application), a glass-ceramic material with no apparent porosity, containing abundant small-sized crystals, was obtained. 5,6 Furthermore, as surfaces displaying such characteristics have good mechanical properties 7,8,9,10 and a silky matt appearance, stemming precisely from the abundance of small crystals, and as inkjet application enables obtainment of homogeneous coatings using just 50 g/ m 2 ink laydown, a study was undertaken to examine the feasibility of using the inkjet technique to enhance the mechanical properties and surface appearance of a substrate (a traditional glaze) on application of a glaze or frit (as ink) that yielded an appropriate fired microstructure (surface coated with small crystals, with no porosity). The effect of the applied amount of ink (dpi), made up of the above Sr frit, on the depth profile of the resulting fired coating, its microstructure, surface roughness, and mechanical characteristics was determined.…”
