Soda ASH (Na2CO3) is one of the most important components to produce glass since this material is able to break the SiO2 network and therefore it determines important properties, however it is also so expensive and there is into the glass industry a paradigm regarding possible issues involved with the Na2O decreases. In this order of ideas, a progressive and methodological decrease of Soda ASH was performed over glasses manufactured following a design of experiments (DOE), aiming to measure and to analyze different mechanical, physical and chemical properties according to the respective ASTM standards or industrial procedures, obtaining as a result non-significant statistical changes in all properties measured when there are decreases up to 2.64 wt. % of Na2O, which allows to think about these decreases as an option for the glass industry issues related to this ore.
