To the uninitiated, it is quite probable that the results that art conservators derive from analytical techniques, may resemble alchemy, but they do not create gold from lead. Instead, they represent the composition of an object as its chemical compo

Results from studies on the ternary system Ribaué kaolin–Carapira feldspar– Marracuene quartz sands were used to test a procedure that we developed for calculation of the energy requirement for firing porcelain. Results obtained vary between 130

X-ray Fluorescence Spectroscopy (XRF) has reached the stage where it is classified as a mature analytical technique. The theoretical principles are well understood. In addition modern instrumentation demonstrates enhanced generator and temperature st

Chromite-rich samples are notoriously difficult to analyze by XRF spectrometry because of the low solubility of chromium in lithium borate fluxes. Our evaluation of the suitability to use powder briquettes of micronized samples implies that reasonabl

Chinese celadon shards of the Longquan type, believed to date from the Southern Song dynasty (1127–1279 AD), were excavated in 1934 on Mapungubwe Hill, a 13th century Iron Age site in the Limpopo valley, South Africa. We studied the shards with Ram

This paper deals with the thermal behaviour occurring during the formation of lithium borate glasses. Thermogravimetric analysis and differential scanning calorimetry were employed to identify reactions occurring during fusion in pure flux mixtures.

This paper describes various ways of stabilising a ferro-vanadium waste. In each case a combination of the ferro-vanadium waste together with fly ash was employed. The methods investigated ranged from physical encapsulation in different matrices to h

During lithium tetraborate fluxing, chromite undergoes incongruent dissolution, in which high proportions of aluminium, magnesium and titanium are dissolved in the flux while some iron remains behind in a residual chromium-rich phase. Increasing the
