I've heard that re-used glass must be cleaned in a certified washer. Consider the glass milk bottle. They wash and re-use. They just need a washer that meets the rules for cleaning, regardless of what was in them. (some people use them for anything and then return them, these also MUST be food safe after cleaning).
Dave Klish, I recently bought a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
