thanks,I will stick with plastic for the rifles and stainless for the small parts
What is the BLACK IRON OXIDE POWDER for? Does it replace the steel wool, and if so how much of it do you use?slyguy2000 said:for those of you looking for cheap parkerization supplies... don't waste money on batteries and such...
Behr No. 991 concrete etcher is $13.98/gal at most Home Depot's (30% phosphoric acid solution)
Krud Kutter brand concrete etcher is ~$15/gal at most Lowe's (40% phosphoric acid solution)
Note: 1 gallon of 30% phosphoric acid solution, makes ~ 16 gallons of parkerization solution) This is cheaper than using Naval Jelly...
manganese dioxide powder is $4/lb
black iron oxide powder is $6/lb
if you want to do Zinc Phosphate (substitute zinc oxide power for the manganese powder)
zinc oxide powder is $4/lb
all 3 dry items can be had at:
The Ceramic Shop
3245 Amber St. 1st Fl.
Philadelphia, PA 19134
store phone 215-427-9665
distilled water can be had at any grocery store.
from what works for me and others, is one cup (4oz of 30% phosphoric acid solution) and 3 table spoons of Manganese Dioxide and 3 table spoons of black iron oxide, with 1 gallon of distilled water.moleman said:What is the BLACK IRON OXIDE POWDER for?

from what I understand is that the Manganese Park needs to be a consistent temerature, if you dunk a really large piece of cold steel into the tank it dramatically drops the temperature of the solution to below boil for a few mins which affects the proper forming of the manganese phosphate crystals onto the steel, preheating large pieces I think is the key to keeping the temperature steady.

I have had great luck with zinc park using pennies with the copper ground off. I do it a little different I think, I put 8 pennies in about 18-20 oz of acid and let them disolve completely. I put that in my park tank which is a six gallon tank, heat it up and add a steel wool pad I've washed with acetone. The parts come out a nice dark charcoal color. After I let one 1919 sit once it got rust spots forming slightly on the park and I figured I mix up a quick solution of muriatic acid and water to try to wash the rust of and it did, but is also left the park a real nice WW2 gray finish. That wasn't what I wanted so I resandblasted and reparked it this time I quickly hit it with WD40 after the rinse.

Yes, the black iron oxide is in leu of steel wool or black iron wire.
For making Zinc Phoaphate bath, substitute 1 cup of Zinc Oxide powder, for the Manganese Oxide powder.
I revised my recipe a little bit, I'm no longer using the black iron oxide power, because it's hard to tell when the solution stops being caustic to steel and ready for finishing... with the steel wool, you can tell, when it stops eating the steel wool...charger0122 said:i parked a receiver stub tonight and it turned out pretty good i used the magnesium out of a few batterys extra fine steel wool and behr concrete etcher.bought a lil electric single eye burner at the dollar store for $8 and a candy thermometer $4.the most expensive thing was the etcher.it was $15 a gallon but a gallon will go a long way.im going to get me some pvc tubes and cap them off and do 2 of my aks in them.im going to order the magnesium for them tho this was just my little science experiment.it worked now im gonna park everything i got.just one question if i use the iron oxide powder insted of the magnesium will it come out black insted of grey?the stub cam out a really dark grey but i want black.
