A new kind of armor

Bryce:  "You know what I wish you could turn into armor?  Hint—it’s a kind of block."

Me:  "Umm…is it an ore?"

Bryce, slowly:  "Nooo, it’s a block."  Pause.  "Obsidian."
Me:  "Ohhhh."

Bryce:  "Yeah, I wish you could make obsidian armor.  Then you could enchant it and stuff."  Pause, then sounding wistful, "I also wish you could enchant armor in pocket edition."
