London, Oxford University Press, 1970, p. Gross, Anthony, Etching, engraving, & intaglio printing. On the bench in front of him are his tools, including the burin, a sharpening stone and a double-ended etching needle. The design is very similar to those of playing cards. It shows Solis as an engraver, holding a burin and working on a metal plate. Balthasar Jenichen, created a portrait of artist and printmaker, Virgil Solis, in the year of Solis’ death.

Stijnman, Adrianus, A history of engraving and etching techniques: Developments of manual intaglio printmaking processes, 1400-2000. As both artist and engraver, he could connect more directly with his audience, and his books, with their co-existent and cohesive images and text, facilitated a transfer knowledge which was particularly meaningful – the kind arguably obtained only where author and illustrator were one and the same. The talent of these early print engravers was not lost on 17th and 18th century successors such as William Hogarth and William Blake, the latter of whom really renewed the art of bookmaking and printing by etching and engraving his own illustrations to accompany his own text. His engraved print, ‘Battle of the seas gods’, with its subtle gradations of light and shadow and its dynamism, undoubtedly inspired the later engravers, Marcantonio Raimondi, who produced engraved copies of Renaissance painter, Raphael’s works, and Albrecht Dürer, whose ‘Knight, death and the devil’ and ‘Saint Jerome in his study’ pieces stood him apart, virtually from all others. In Italy, painter Andrea Mantegna, who had turned his hand to engraving, earned widespread acclaim for his clarity and boldness of image. By the 16th century, though, some names had become synonymous with fine line engraving. As Anthony Gross points out in his Etching, engraving, & intaglio printing, most were known to us by their work only, historians having invented names for them based on their prints – ‘Master of the Playing Cards’, ‘Master of the Garden of Love’ and ‘Master of Saint John the Baptist’. We are fortunate to know their names, since so few early engravers have been identified. It would be almost a century later, in 1562, when the first depiction, by Balthasar Jenichen, of an engraver at work on a copper printing plate appeared. Though engravings on metal emerged as early as the 1430s, the earliest illustrated act of engraving on a metal plate appeared in c1465, when Baccio Baldini engraved a goldsmith at work on a flat, rectangular plate in his shop.

It likely found its origin in the workshops of the gold- and silversmiths, where the craftsmen not only used the method to decorate and inscribe their metalwork, they generated printed impressions as a means of recording it. Intaglio describes any printmaking technique in which the image is produced by incising into the printing plate the incised line or area holds the ink and creates the image. It may be concluded that the etching with hydrofluoric acid at the tested concentrations (1%, 5%, and 10%) does not influence the fatigue failure load of feldspathic ceramic inlays cemented on premolars.Line engraving, with its prints comprised of incised lines, was the most widely adopted, and probably earliest, method of intaglio engraving. Regarding the fracture mode, there was a predominance of interfacial fracture (50%), followed by cusp fracture (34.6%). Fatigue data were analyzed by one-way analysis of variance.

The tested samples were analyzed under a stereomicroscope for failure analysis. The initial load (585.5 N) was applied on the slopes of the cusps (labial and palatal/lingual, simultaneously) through a cylinder attached to the test machine (Instron ElectroPuls E3000). The restorations were cemented and the fatigue failure load (in N) was determined using the staircase method (10 Hz 10 5 cycles in each step). The inner surfaces of the inlays were etched and received an application of a silane coupling agent the dentin and enamel were treated appropriately for the luting system (RelyX ARC, 3M-ESPE). Preparations were scanned and restorations were milled by a computer-aided design / computer-aided manufacturing system. Teeth were randomly assigned to three groups (n=20): HF1, HF5, and HF10 (etching with hydrofluoric acid for 60 seconds at concentrations of 1%, 5%, and 10%, respectively). A total of 60 upper premolars were embedded in plastic cylinders with acrylic resin (up to 3 mm below the cement-enamel junction) and prepared using a device specially designed for that purpose. The aim of this study was to evaluate the effect of etching, with different hydrofluoric acid concentrations at the intaglio surface of feldspathic ceramic inlays, on the fatigue failure load of restored premolars.
