Don't know of a tutorial, but standard glass has a refraction-index of 1.58 (Setting in bryce=158). Crystal glass has a higher refraction setting. You can play with the specular settings, to get bright highlights. How many lights are placed at the exact top of the light-dome? if you have only one light there make sure it gives (much) more light than the other lights in the dome. otherwise your specularity get's to dim and blurry to give the glass a nice shiny effect. I'll make a small test-render if I have time to show you what I mean exactly.
