parkerizing

Parkerizing requires Maganese dioxide and phosphoric acid, plus a bit of iron (steel wool or filings) in boiling water. Would it be possible to use the manganese dioxide from a standard (non alkaline) dry cell? If I rinsed the mixture with water, the ammonium chloride, being soluable in water, should wash out. The manganese dioxide, being non-soluable in water, but soluable in acid, should remain???

Or alkaline battery - rinse out the sodium or potassium hydroxide(alkalie)?

What is another easy to get sourse for manganese dioxide????

There have to be better sources, cost-wise, than chemical supply houses. I've just heard ceramic supply houses carry it at less than HALF the price.

Well, you don't need food-grade USP 99.9999% pure...

Found both manganese dioxide and zinc oxide for less than $8 canadian per kilogram at a local pottery supply. Will pick up tomorrow - less than 10 miles from home.

Ah, excellent. I'll have to check that out. I've got the sandblast cabinet and the information, and now sounds like I've got a lead on the chemicals. Thanks for the followup!

Apparently Titanium Dioxide, used as a white pigment, is the active ingredient in the pre-wash. After cleaning and degreasing you dip in the Ti solution, and then, without drying, into the Park solution.
