This is accomplished by the way they are compelled to set off their figures as an intelligible scheme of thin raised lines and inlay against a plain ground.
Close inspection reveals surfaces delightfully animated by straight and loopy brush strokes, inscribed and raised lines and dots, dashes, dollops and squiggles.
All flat glazes between the raised lines were found to contain lead as a flux.
Raised lines on the surface of the brick bodies separate colored fields of glaze.
Low lead levels in both raised lines suggest they would have had a higher melting point than the colored glazes.
In this case, the glazes would become liquid upon firing at lower temperatures and spread between the raised lines which would have remained solid, acting as an enclosure.
The fired brick bodies are covered with colored glazes separated from each other by raised lines as seen on brick fragment FSC-A-3d (Fig. 7).
However, stacking faults originating at the Ge SiO2 interface and terminating at the Ge surface are polished at a slightly reduced rate, and show up as 1 to 2 nm raised lines on the polished Ge surface.
Microscopic examination of the raised lines in cross-section showed they are a distinct material in texture and particle size as compared to the brick body and the colored glazes.
The screw down crown design and raised lines along the outer edges of the case's exterior give the watch a subdued industrial vibe, which works very well with the instrument-style face.
The decoration of the front cover is divided into fields bordered by raised lines.
