Hi all,
We've just taken delivery of two ML cast iron sea recovered 4 prs, a matching pair, almost certainly of commercial background, probably circa 1830.
We've had fiberglass tanks made & currently the barrels are in fresh water. I gather we need to put sodium hydroxide into the water & run a low current thru it with anode & cathode - I totally lack experience in this area & must confess to having virtually no idea of how to set it up.
Has anyone any idot proof & clear instructions that would help out here please?
Any help very much appreciated!
Thanks, Adrian.
