So any way I am planning put these into a vat of Molasses which is natural product and has reportedly had some brilliant results on both ferrous metal aka Steel ~ and brass ~
I have a test lot down now with one soaking a 3" mortar tail fin - steel ~ and another with misc brass , copper and a sad nickel plate spoon ~
Will report back on results ~
Oxalic acid is good for iron / steel based items. You can buy it in crystal form and make up the solution yourself. A 1kg tub would make 10 litres of a 10% solution which should be enough to submerge your items in the right sized container.
But please be carfull with oxalic acid! Do it outside out of the wind , with chemical gloves!
Informe your self well regarding anything chemical you use .And read "Toxicity and safety"paragraph on,
Oxalic acid - Wikipedia, the free encyclopedia
Always looking for Belgian Congo stuff!
No need to go to Wiki.......we have the information in a sticky thread in this very forum
Dangers of Oxalic Acid
Thanks for the input Blokes..
I actually pulled the 4.5" out of the 'vat' this afternoon after returning form an an amazing recce this morning... and the result is &*^*^ amazing after some ten days ~
I will to some pictures in the next few days `
(I have some four 'vats' running at present ~ either steel as in shell cases or brass ~ )
I finally pulled the first test artillery shell out of the Vat containing Molasses ~ the result is absolutely spectacular ~
Removed.. brushed and hosed to remove the residue ~
Truly amazing result
That 4.5 looks lovely. And to think you just picked it up off the ground. Is there any date on it?
At this point, it have only found the engraving of 'BHP 5540 MO ' BHP is the traditional 'BIG AUSTRALIAN' ( Broken Hill Prop) steel manufacturers ~
I will look again but have not seen a date ~ but suspect it would be <1940s> ~ although the 4.5" were hang over from the First World War ~
And yes it/ they have suffered extreme heat < 45 deg plus> and severe wet ~ and even fire damage for 70 years ~ pretty amazing!
I found a date on the Primer head ~ obviously may not be totally relevant to the shell casing but ~
