: Hi, I've spent almost all day trying to find a figure of the hardness of glass. It's glass in i.e. bottles etc. that I'm searching for.
: I'll corrolate this to the hardness of steelpipes, when we build pneumatic conveying systems that handles household waste. We transport waste in steelpipes with air and the glass is eroding our pipes. I need to explain for some collegues tomorrow that if we transport a material harder than the pipes, the wear is much higher.

Hi Tord
It depends on the type of glass, but generally it will be around 700 vickers, roughly the same hardness as a hardened tool steel. So, yes it would be very abrasive or erosive to mild steel.
