Dave, is the casserole dish Corningware?

If it is, it is, quite capable of holding ferric acid. Did it get eroded at all? If Corning, no it didn't, stuff is good anything else toss it, especially "made in China". Stuff is better than glass if it's Corning as it is less likely to break.

Place I worked at had acid tanks and added purified water to the tanks to make up for evaporation in answer to your other question Dave. Add some bottled purified water and test it to see what it does. BTW, the tanks were lined with ceramic made by Corning. They had phosphoric acid which is worse than nitric acid. They put that crap into soda drinks and it prevents your body from absorbing calcium, not to mention eating the enamel off your teeth. I used Pepsi once to etch aluminum, it just takes longer, but it does etch it. Had to weld it and it had to be clean, etched overnight in cola. Kind of scary what they put in our food huh? So a big cola two liter bottle cut down the middle will hold ferric acid as well too and you can leave your Mom's dishes alone Dave.

Aluminum cans are lined with a special plastic to keep the acid in the drink from dissolving the can. Just FYI.
