It has been determined qualitatively and quantitatively , the presence of chemical elements in a sample of imported glass frit yellow , also , some of their physical properties. This conventional techniques were used in both cases , and analysis techniques Fluorescence energy dispersive X -ray (XRF ) and neutron activation analysis ( NAA ), which can detect elements such as zirconium , lead, niobium , arsenic , chlorine , manganese, vanadium , dysprosium , hafnium , barium, and others which are in very low concentration. During the investigation it has been established that the highest averages of the elements present in the sample are silicon , boron , sodium and titanium , and also the color imparted to the frit glass is due to the presen...
