Mise au point d'un verre sans plomb présentant les caractéristiques du cristal commercialisé par Baccarat

Abstract : The environmental standards concerning the lead discharges led the Baccarat company to be interested in the development of a lead-free vitreous matrix showing the characteristics of the crystal (density, refractive index, expansion coefficient and viscosity). In addition to these properties, the new matrices have to be compatible with the current process of manufacturing and the lead oxide substitution must be carried out by a non-toxic element. Industrial production of these new glasses will be made possible only by (ou in the frame of) a severe control of their aggressiveness with regard to (ou as regards) furnace refractory material. So, their corrosivity was studied and compared with the one of the reference crystal. Finally, the determination of the fining conditions (removing of the residual bubbles remained trapped in the glass melt) was performed in melted glass medium by the use of electrochemical methods at high temperature.
