Building a tetrahedron of molecules sounds less like manipulating "glass" than growing a crystal. I feel like the fractal properties of crystals could be used to grow a very precise mirror that would provide the constructive interference this mirror needs. Instead of a fluid, it would be a single unit, and the molecules would be trying to arrange themselves into shape. I'm no expert though, and I have no idea whether the physics allows it. The technology already exists in the semiconductor industry for making extremely pure silicon wafers. Each wafer is actually a slice of a single gigantic silicon crystal. [1] If that could be used with a transparent material, I think it could be a decent alternative to glass.
