Glass manufacturing? – how often do glass furnaces shut down?

are you nuts? last I heard, the float line at LOF was down for a furnace rebuild ~10 years ago. It is scheduled for its next rebuild in another 15 years. it takes a month to get the glass running again. email LOF and find out for yourself.

other lines not using float lines (glass bending lines, for example) are capable of being shut down over the weekend. I am pretty sure they don’t do this, though. Guardian Glass would be a good source for this info.
