CME and Bottlewasher Posted March 29, 2015 Share Posted March 29, 2015 Hi All, Please excuse my ignorance, I need to blacken a few Lost Wax Brass (LWB) items (Vac hoses and the like) and I would like to know what is the best product to use? Up until now I have used etched primer and the like as an over all coating for an entire model (ie multi-media kits) and that's been fine, but using my 'ten minutes here and ten minutes there' modelling strategy (ie when life doesnt allow much time for model-making) I am replacing some white-metal vac pipes and the like and doing the odd bit of fettling so as to finish one or two vehicles off ready for Down Ampney and layout usage. I know that there are things out there like Gun-Blue and Carrs et al make various products to coat normal brass and NS et al, in the USA (so not financially viable to import) there are even 'safe for user' and environmentally friendly Gun Blues etc, but I know that some of these products wont adhere to Lost Wax Brass. I see that there are a fair few Posts on RMW re 'blackening' various metals, yet it would be good to hear of the best product for LWB from those who have tried it, ie an easy tried and tested method. Many thanks in anticipation. Kindest regards, CME Link to post Share on other sites More sharing options...

Derbys65 Posted March 29, 2015 Share Posted March 29, 2015 Glad to be of help, the blackening seems to vary dependent on length of time you leave in solution Link to post Share on other sites More sharing options...

And works very quickly Hi Derbys65, Many thanks, newbie or not, such things, like status matter little, sometimes an enquiring mind and a fresh pair of eyes pay dividends I have few of GJH and Hobby Holidays' useful products and when at Bristol I nearly picked up a bottle of their Blackening but they were so busy there was little chance to seek advice and buy some - doh! May I ask - have you tried it on LWB specifically (it seems to treat most metals)? With many thanks, CME Link to post Share on other sites More sharing options...
RMweb Premium BR60103 Posted March 30, 2015 RMweb Premium Share Posted March 30, 2015 One of my friends uses tincture of iodine. I tried it once and it seemed to work, although possibly a bit on the rusty side. Try it on a coupling first. Link to post Share on other sites More sharing options...

Hi BR60103, That's interesting (as Iodine is an antiseptic) - as long as its not from Chernobyl - I will give it a try if its still available, but I would have thought it would work better on steel as opposed to LWB though?

RMweb Gold teaky Posted March 31, 2015 RMweb Gold Share Posted March 31, 2015 I have successfully blackened brass etched parts and brass chain with Nickerson's Professional Cold Blue which I purchased from a hunting supplies shop. I'm afraid I cannot help with LWB specifically though. Link to post Share on other sites More sharing options...

Gun Blue is okay on etch - but I didnt want to have to experiment with LWB Im sure someone must have a tried and tested method for LWB - perhaps it is the same as brass etch?

buffalo Posted March 31, 2015 Share Posted March 31, 2015 Just tried Birchwood Casey Brass Black on a cast spring and axle box. It works fine, just as well as on brass sheet, if the brass is clean. Nick Link to post Share on other sites More sharing options...
