  • Alum versus Tap versus Corningware

    On a thread a while back someone asked how to remove a broken tap.

    There were a lot of good answers but one that I researched and wanted to try was the use of Alum.

    Well to tell the story, it worked!! But now I have a new problem.

    I was working in some aluminum and got in to much of a hurry in tapping for 8-32. As luck would have it, I broke a tap.

    Now what do I do?

    Well I come to the frendly Home Shop Machinist mag web site and do a search and find someone posting about using Alum to eat away the tap.(And it does) But they didn't say how long this was going to take.

    I didn't really time it, but it took probably at least 8hrs to cook this tap out of my prized project.

    This still wasn't the reason I am posting this item. My problem now is, how do I get this Alum out of the Corningware I borrowed from my wife?

    I am still trying, with no sucess yet, but me think that it would have been easier to have started the project over!!

    Go to the store buy a new one and bury the old very very deep
    Forty plus years and I still have ten toes, ten fingers and both eyes. I must be doing something right.

      I sympathize with you. I remember putting sulphuric acid in one of my wife's glass baking bowls. She had a fit. Didn't understand the reasoning, I guess. I explained that I'd wash it after use, but that wasn't sufficient for her.....go figure?? She also didn't believe me when I said that I thought the "frosted" bowl looked better.

      Afterwards, I bought some glass containers at a flea market, for my projects. She never borrows my stuff.......

      BTW......Never put water into acid. Always put acid into water.

        I found broken dishes buried in my back yard while digging a trench.

          Quick and check the internet for the nearest corningware outlet store near you, or where you can order various patterns from Corning. there are also some "re-sellers' of old pattern corning ware out there.

          Meanwhile, you kind of "hide" the dish.
