“…The mobility of the metals remaining in the vitrifi ed slag is lowered [45, 46, 51-53, 58, 67] and usually even lower than for other techniques such as cement stabilization [61]. The higher the share of amorphous fractions, the lower the metal mobility [58]. Silica might be a critical component enhancing the formation of glassy amorphous phases [58,68].…”

“…The higher the content of silica in the feed material, the lower the mobility of contaminants in the vitrifi ed slag [69]. The addition of silica might also improve the resistance to acid corrosion [58,68] due to a higher share of glassy amorphous phases achieved [68,70]. In the amorphous silicate framework, Si can partly be replaced by Al [39].…”

The area's natural analogues, vitrifi ed forts, combustion technology, and vitrifi ed waste have been reviewed. The purpose was to identify if investigations of vitrifi ed rock in hill forts might be warranted for assessing the long-term integrity of vitrifi ed waste in natural environments. Wastes that are being vitrifi ed include ash from incineration of domestic waste, contaminated soil and fi ssion products from reprocessing of spent nuclear fuel. It was found that vitrifi ed materials in at least 200 hill forts constitute good anthropogenic analogues to vitrifi ed waste. The compositions vary considerably from site to site and even within one site and may correspond relatively well to the spans of parameters in the various vitrifi ed wastes. Glasses in vitrifi ed forts compare favourably to archaeological artefacts which are soda-and potash-based and consequently have different corrosion behaviours and may weather too quickly. Natural glasses might be too limited in composition variation and are perhaps also too durable. Combustion technology considerations based on quality of heat analyses indicate that at least some of the vitrifi cations of hill forts were carried out with the specifi c purpose of achieving strong and durable constructions. This makes it considerably easier to envisage how the vitrifi cations might have been carried out, and this, in turn, facilitates comparisons between anthropogenic analogues and modern vitrifi ed wastes.

An information survey was conducted in the areas of natural analogues, vitrified forts, combustion technology and vitrified waste. The main purpose was to identify if vitrified stone material in hillforts might be used as anthropogenic analogues for glass containing waste. Such comparisons are needed in order for predictions to be made regarding the long-term integrity of the waste forms. The scope was to compare the chemistry as well as the processes used for the generation of the glasses.It was found that the vitrified forts contain glass material with wide variations in composition of the major elements. They cover and exceed those in the glasses made of waste with only the exception of phosphorus. Natural glasses as well as archaeological glasses show much narrower ranges of compositions, and they do not coincide with those of the glasses containing waste.Quality of heat analyses indicated that it is likely that the stone material in the forts was melted for the purpose of obtaining long-lasting structures. This narrows the range of possible processes used, and facilitates reconstruction of the ancient methods by means of testing. This, in turn, provides possibilities of comparison between ancient and modern methods, which can then be used as a basis for validation of the use of the analogue.
