Broken glass

I am annoyed. I put this glass down by my chair this morning after drinking some fruit juice. I went out to an appointment, came home, went to walk into the kitchen and caught the glass with my foot. Of course it smashed. It had a heavy base but the ridged sides were thin and delicate. Result, glass shards everywhere. I hope I have swept them all up.

I don’t know if it’s possible to make glasses like this stronger, it was an expensive glass and I’d like to buy a replacement, but dare I? Do I have to treat it like a rare jewel?
