The article examines Brazilian refined earthenwares known as faiança fina (fine faience) and relates ideas about its production to the contextual backdrop of hygienist discourses in the city of São Paulo in the early twentieth century. Based on an analysis of glaze components, moisture expansion processes, and technological aspects of the production of earthenware recovered from the Petybon arc...

The effects of a typical glaze ice accretion shape on the performance of the M2129 S-duct inlet are computationally investigated for a range of flight Mach numbers. A Reynolds-Averaged Navier-Stokes (RANS) code with k-o> turbulence model is used to simulate the compressible viscous flow in the S-duct inlet. The glaze ice accretion on the cowl lip is modeled on a steady-state basis f rom N A S A...

DESCRIPTION OF WELLCOME TILE* The tile is an elongated octagon in shape. It has a blue tinted glaze, and bright blue decoration with the motto in maroon. The sides of the tile are chamfered, and the glaze on the back is in irregular patches. The design of the Society of Apothecaries' Arms-with ribbon-like scrollwork to the sides of Apollo, who has an unusual 'Red Indian' headdress-is quite dist...

Raman micro/macro-spectroscopy allows for a non-destructive remote analysis: body and glaze, crystalline and amorphous phases can be identified, including the nanosized pigments colouring the glaze. Last generation instruments are portable which allows for examination in museum, on sites, etc. This paper gives an overview on the potential of Raman spectrometry technique to analyze ancient ceram...

The current research deals with an experimental study in the Crawling Glaze technique under low temperature range (980) degrees Celsius, where a local bentonite clay was used as catalyst to achieve effect of on ceramic surface, and white (Akashat) chosen body for application by adding non-plastic materials such silicic sand grog, well kneading (burnishing) surface be ready this technique, homem...

A smooth white glaze, (Figure 1) with a buttery surface and smooth breaking on edges, just enough change of whiteness in a crevice pooling, seemingly opaque when thicker, but with a certain glow, a slight grey showing through. It crazes slightly, a fine webbing of cracks. Not enough to be decorative crazing, and not enough crazing to make me abandon the glaze, but enough crazing that I would li...

Shards of Blue-and-White Ming porcelain from shipwrecks Portuguese ships found on the coasts South Africa plus a shard Mombasa (Kenya) were analyzed by optical microscopy, SEM-EDS and Raman microspectroscopy (458 nm). Whereas signature body paste compositions which are based mullite, quartz an amorphous phase with minor presence anatase feldspar very comparable whatever variable alumina content...
