This paper examines two pieces of Ru porcelain glaze excavated from the Qingliangsi kiln site. Compared with R1 glaze, R2 was fired at a lower temperature and cooled slower rate. The chemical composition, microstructure, corrosion mechanisms glazes were analyzed by optical microscopy (OM), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), micro-Raman spectroscopy, tra...

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...

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...

The novel heterometallic aggregates [Ag(8)Cu(2)(C(2)C(6)H(4)X)(6)(PPh(2)C(6)H(4)PPh(2))(6)][PF(6)](4) (X = H, 1; OMe, 2; NMe(2), 3) were prepared by the self-assembly reactions starting from simple precursors. These compounds consist of the central [Ag(6)Cu(2)(C(2)C(6)H(4)X)(6)](2+) clusters capped by two tripodal fragments [Ag(diphosphine)(3)](+). The solid state structures of complexes 1 and ...

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...

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...

The electrical performance of transmission line insulators will decrease dramatically under ice-covered conditions, and ice flashover may occur operating voltage. There is no direct effective monitoring method for cover on lines. In this paper, the interface quasi-distributed fibre Bragg grating (FBG) used to study positioning detection glaze icing loads composite insulators, a mechanical lever...
