Glazing technique

Ceramic Materials, Glazes and Glazing Techniques in the Ceramic Industry, Helsinki, Finland, 26-21 September 1999. 

Elemental chemical analysis provides information regarding the formulation and coloring oxides of glazes and glasses. Energy-dispersive x-ray fluorescence spectrometry is very convenient. However, using this technique the analysis for elements of low atomic numbers is quite difficult, even when vacuum or helium paths are used. The electron-beam microprobe has proven to be an extremely useful tool for this purpose (106). Emission spectroscopy and activation analysis have also been appHed successfully in these studies (101). 

Objects in the vicinity of an explosion can often serve as useful post-blast witnesses. Thus for large explosions damage to structural elements of buildings, street furniture, motor vehicles, and glazing can all prove informative. A number of authors have published studies that provide guidance on both damage assessment techniques and interpretation of the data [2-7]. 

Bottger s first porcelain pieces were not of the same high quality as those imported from China, and he did not yet know how to produce a glaze. However he was confident that he could perfect his techniques and eventually produce porcelain of finer quality. 

Use of inductively coupled plasma-mass spectrometry (1CP-MS) coupled to a laser-ablation sample introduction system (LA-ICP-MS) as a minimally destructive method for chemical characterization of archaeological materials has gained favor during the past few years. Although still a relatively new analytical technique in archaeology, LA-ICP-MS has been demonstrated to be a productive avenue of research for chemical characterization of obsidian, chert, pottery, painted and glazed surfaces, and human bone and teeth. Archaeological applications of LA-ICP-MS and comparisons with other analytical methods are described.
