Those "glasses" are called "getters". They are used to remove residual gases left inside tubes after vacuum pumping.

@jasonbourne52 , the “glasses” are typically made from mica and are used to support and align the tube internals inside the glass envelope. In some instance, they may be attached to the getter.
