Hi,

It's come to my attention that one can use glass as a lubricant for height temperature metal working operations. I'm very interested in this could anyone please give me any information about this, papers, articles and book references as well as a company I can get these glass coatings done.

Thanks so much.

darkelf,

I've never heard of using glass as a high-temperature lubricant, but it does make sense. When glass heats up its viscosity goes down and it's inert to metals. I'm not sure about the wetting properties of glass with metallic surfaces, but glass can be used as a crucible for melting low melting point metals such as Al, which means the wetting properties can't be that bad.
