Oversized Brass-Rimmed Protective Goggles

This is a lost artifact, known only through ancient stories of long-deceased ancestors, and has not been discovered in Ur. There’s a list somewhere of all the things from which this particular class of protective goggle can protect the wearer. Weena, one of the great scientists of the beforetimes, ran a series of tests flinging various substances at testers and making a mark on her notepad whenever someone said “ouch”, and a larger mark if they suddenly stopped saying anything at all. Erring on the side of caution, most goggle-wearers trusted them to protect against hard airs, soft liquids and lukewarm steam, and learned just to avoid Weena entirely.
