Can glass be magnetised?

Someone asked me today if they could revolutionise their recycling business by making glass magnetic and thus easier to extract from recyclate...?

If glass were magnetic, how would you separate it from the steel?

There are magnetic glasses and crystals but they have the disadvantage that like metals they are opaque because light interacts with the magnetic properties.  Coarsely divided magnetic particles could produce a weak magnetic effect which could allow partially transparent material and a dynamic separation method from steel.
