I am in the process of finishing my MM. I went with 3/16" thick Mirror Pane Glass vs the Acrylic for a couple of reasons.
- To support a small local business
- No chance of waviness in the glass.
Yes, it is substantially heavier and brings about a spectacular boom when dropped vs. Acrylic.
My next project which will be a laptop screen will use acrylic because of the costs associated with using glass.
