Glass is totally recyclable, the problem is you can’t get clear glass out of anything that has color in it, which a lot of stuff does.

It’s also not really saving any energy or valuable resources, and glass is heavy and fragile.

Glass doesn't have to be clear for most disposable uses; it's mostly useful in things such as windows, where you probably want to keep them around. For bottles, it doesn't really matter much.

Glass is more on the reusable side, which used to work great for soda and milk bottles until the companies decided plastic was cheaper.

Recycled glass can be mixed with virgin stone chip to make asphaltic concrete.

(Which of course uses fossil fuels for the bitumen; possibly even more than the equivalent mass of Portland cement concrete.)

I'm not aware of any other significant uses for recycled glass.

Nearly all glassmaking involves adding all the glass bits you cut off or broke back into the kiln. Almost no glass is actually 100% virgin glass. So glass is absolutely recyclable.

The only caveat is colored glass can only really be used to make the same color glass (at least economically).

I should have said, post-consumer glass.

House coatings?

It's not un-recyclable, it's hard to move around and doesn't save a lot of energy compared to new raw materials.

Correct, glass needs hardened containers and slower acceleration.
