Finitoglass was a type of glass known for its durability. It could withstand X-tonic rays for an extended time, based on its thickness. (TV: Midnight)

On the planet Midnight, the Leisure Palace was fitted with huge domes of Finitoglass fifteen feet thick, ensuring protection from the rays. In the shuttle buses the glass was only strong enough to hold back the radiation for a few minutes. (TV: Midnight)
