make glass rwalls break in one smack

[The Gorog]

I might not know what kinda walls you mean maybe? Someone should post a picture of the exact glass walls you are talking about

Know how you can just click a tile with sheets to build girders? It by accident made you able to make girders with glass sheets, then add glass to the girder.
You can make walls that just look like the normal walls, but looking more like glass and actually being seethrough.

And from what im reading here you can even make reinforced versions.
