Domes of all colors!


Domes of all colors!

Ah!!... Astronomical observatories... Places of domes of all colors!.. No?
Oh yes! Is not White composed by all colors?? Well, but there really are other dome colors too.. Green domes: Why not?

This recycling container for glass, for instance, is -- like our Sun -- green. And it has the shape to mingle with its astronomic-purposed companions. But this non-atypical fiberglass container further has two round entrances, to allow bottle-sized glass objects (or chunks of them) to be thrown in. However, is this not a strange asset to find in an observatory?
Astronomical observatories are filled with glass objects! I would estimate 5% of total glass to be on bottled drinks at the bar; maybe 10% on windows; but quite possibly more than 70% of the volume of glass to be in telescope mirrors!
Now, why would someone design bottle-sized glass intakes when most of the surrounding recyclable glass clearly will not fit through them?? Are they saying that when a telescope mirror breaks, it does so into small enough pieces?
What other strange things might one find on astronomical observatories?
