This video produced by Vetrazzo shows the basics of fabricating recycled glass slab materials, such as cutting, feed speeds, polishing, overhangs, sink cut-out reinforcement, suitable applications and the effects of temperature change.
While this is certainly just a broad overview, it does explain how fabricating this type of material is similar and different to fabricating other hard surfaces, such as granite.
