Is it borosilicate glass?

Yes, it is Borosilicate glass, can tolerant to repeated heating and cooling, it meets the industry-standard for chemistry use.

Is this mug sturdy and heavy enough for daily use? Or is it more a novelty mug for occasional use?

If say more novelty..BUT I've had a few of these for years. If you are careful with them they last just as long as any glassware. If you're a goon and a moron then it will break easily

How tall is this mug? I'm curious if it will fit under the espresso spouts of my machine.

Dimensions ( H x W ): 4.5" x 5.5"( including handle ).

What is the diameter of the opening?

I haven't measured them, but I can tell you they're definitely larger diameter than almost all of the rest of my mugs (which are 10-oz) vs. this one at 16 ounces. That isn't necessarily bad; depends on your preference. But bigger? Definitely.
