As a Jupiter mass gas giant in a very hot location the glass is unlikely.
The planet would initially have been supersaturated with hydrogen and all the Si would be Silane (SiH4). Metals such as Ti famous for the TiO2 bands in stars would remain as oxides if they are reactive such as Mg or Ca and may form hydroxides in the atmosphere of this sort of planet but the Si part of the glass would be absent.
The deep blue colour is likely a combinbation of extensive cloud free atmospheric depth on the dayside (no cloud condensation available) coupled with background scattering from minute amounts of metal oxide & hydroxide dust on the upper cells dredged up from the metal oxide & hydroxide condensation zone cloud decks beneath the upper cells. The other feature giving the deep blue colour is likely the same as occurs in Neptune which is an atmosphere with CH4 and (in this case SiH4) molecules abrorbing the red light before it is reflected from the near transparent atmosphere.
With time this planet is likely to lose its excess H2 & a fair chunk of He which is likely to be lofted out of the atmosphere and blown away in a tail on its stellar wind.@ that point, photolysis of molecules of H2O, NH3 and CH4 (@ other nonmetal hydrides) will, produce a more oxidising atmosphere with time as there will eventually not be enough spare photolysed H in the atmosphere to mop up free radicals. The first effects will be the precipitation of high temperature metal oxides & possibly carbides out of the atmosphere, and also the formation of high stability temperature organic molecules (probably on the cooler nightside of the planet). This process may actually increase the transparency of the atmosphere of the planet enhancing the deep blue.
