Can you use borax as flux for forge welding?

In the realm of metallurgy and welding, the choice of flux is crucial to achieving a strong and reliable weld. Given that borax is a commonly known mineral compound with diverse industrial applications, it begs the question: can one indeed utilize borax as a flux for the intricate process of forge welding? Forge welding relies heavily on the selection of an appropriate flux to remove impurities from the metal interface, ensuring a clean bond. So, the question stands - does borax possess the necessary properties to effectively function as a flux in this demanding welding technique?
