A standard sample of white glass frit from Mexico was used to perform the physical and chemical analyzes, the results of which have been taken into account to prepare two experimental formulations of white glass frit from domestic and imported raw materials. Ulexite (U) was used in the first formulation and boric acid (B) in the second. Likewise, a study of the volume of glass frit imports was carried out, as well as the countries of origin. Formulation (B) is the one that presented the best results to the physical and chemical tests to which they were subjected, but which still does not meet the requirements of an imported glass frit. It is recommended to make new formulations that allow obtaining a better quality white glass frit.

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 presence of iron , copper and lead are present as oxides, in the aggregate pigment . We conclude that the technique proves to be effective AAN to quantify u...
