Elaboración artesanal de vidrio sódico cálcico y vidrio de plomo utilizando técnica de colada para su fundición

Abstract

The purpose of this work is to determine the effect caused by the use of borax as a flux in the characteristics of lead and caustic sodium glasses according to the plate casting technique. For the following practical case, a literature review was carried out on the raw materials involved in the formulation of the glass, as well as knowing the energy problems that arise in the casting process if borax is not used to reduce the amount of useful energy for carry out this process. Types of glass such as lead and caustic sodium use pure reagents in their composition (close to 95%) and a different formulation because the application of each type is specific. For lead glass, lead oxide (PbO) is used, with Pb+2 providing stability to the glass, however, for caustic soda glass, it incorporates alumina, which offers greater resistance to the glass.
