Aluminizing......
The 120 inch diameter James Lick telescope mirror is
aluminized....must be good!
They have no way to glass coat the mirror. The mirror is re-aluminized
every 7 years on site in a specal chamber in the basement of the
observatory. The techie told me if they had the facility to glass coat the
mirror it would last forever.
