Rocks contain a lot of water and so require a long gentle drying process of days or weeks to avoid steam building up within the rock and breaking the rock and so also breaking the glass in any attempt to fuse the rock into the glass.
Rocks and glass have radically different expansion rates and viscosities from glass. Also rocks are not consistent in their characteristics as they are made up of different proportions of materials even within one site. So fusing rocks to glass is likely to be unsuccessful.
However, you can use the rock as a master for a mould. Make a mould of the rock, then pour investment material into the mould and use that to drape the glass around. Then glue the rock into the shaped glass.
Glass is in widespread use largely due to the production of glass compositions that are transparent to visible wavelengths of light. In contrast, polycrystalline materials do not in general transmit visible light. Glass has the ability to refract, reflect, and transmit light following geometrical optics, without scattering it.
