摘要: Abstract The interactions between glass and water are many-sided the results of such depend on many parameters. It is well known that stability in depends composition glass. Amongst further parameters temperature plays a specific role because primarily determines whether interaction takes place with vapour or liquid water. In general durability very high. good condition surface ancient glasses, exposed to for long time, proves this impressively. However, impression usually does not show complicated occur yielding remarkable change structure microstructure surfaces. These phenomena shall be discussed detail. influenced by compounds dissolved This must taken into consideration especially when judging long-term behaviour limited aqueous volume. problem important some practical cases. was found corrosion continues even after components have reached their saturation, however, lower rate.
