For the analysis of mediaeval glass fragments, the inductively coupled plasma (ICP) and the Grimm glow discharge source (GDS) were used. For ICP measurement, the glass samples were digested with a mixture of sulphuric, nitric and hydrofluoric acids. For GDS investigations the glass powder, mixed with Cu or Zn powder was pressed to pellets. The sputtering rate was investigated in the case of standard and glass samples. Analytical curves were found to be linear over a wide concentration range for the investigated elements Fe, Mn, Al, Zn, Cr, Ni, Cu, Sn, Ti, V, Pb and Ag. The limits of detection and relative standard deviations met the requirements for archaeological glass analysis.
