You could soak it in Mari Mayans, but it might disolve the glass...

Hills will definitely etch the glass and the fumes are quite caustic. Sorry Zman.

Lemony Lasala should do
In fact you'll leave it
sitting in there untouched
for so long it will take no
time at all to safely
dissolve it away.

Have you tried calcium removing products like CLR two to three times? I've used it with pretty good success.
You don't need to worry about the acid etching the glass.

Avoid antiques at all cost.
GO ANCHOR HOCKING!!!

Sounds like it involves a lot of hardware. Isn't there an easier way?

Thanks Jay, I'll email you.

The best way is to tumble the toppette in a gem tumbler, with a custom made acrylic barrel to hold the item.
You will need Tin Oxide for the polishing medium, and angle cut copper #16 wire mixed in the medium.
Drop me a line and I can give more information.

It seems that most antique carafes and topettes have at least a little calcium scum in them. Sometimes it's only visible when the glass is held up to the light, other items I've seen are heavily encrusted. I've had limited success removing it and was wondering if the collectors and chemists out there might have some ideas as to what might work.
I've tried soaking in white vinegar. A tip that I found on the web was to use Polident tablets followed by using uncooked rice in water as a mild abrasive, swirled around in the container. I've also read that petroleum jelly, applied in a thick layer and left overnight works, but due to the narrow opening of a topette this wouldn't be practical. I didn't have much success with CLR and was worried that the acid would etch the glass.
The best thing would be to not buy glassware with scunge on it. Since many French sellers think it's best to leave an item in it's "own juice", it's a flaw that frequently doesn't get mentioned and doesn't prevent them from listing it as being in tres bon etat. Haze does not show up well in photographs either.
