Hi,

For the glazing material, use V-Ray glass material. Make sure the Reflection is set to white and Fresnel is on.
For sharper shadows with dome light, you need to use an image with a higher dynamic range.

If you can send us a screenshot, I think it will be easier to advise you.

Best,
Ana

For sharper shadows with dome light, you need to use an image with a higher dynamic range.

This, and also have suitably small light sources in the HDRI used.
A big light source will produce soft shadows, while a smaller one will produce sharper ones.
