Household blackening fluids.

[Senior ole salt]

I'd like to blacken my copper harpoons and copper fittings furnished with my Model Shipways whaleboat kit.

Are there any common kitchen or household liquids or powders etc.that can do that ?

 

Thanks S.os

Are they really Copper or are they Brass? Not sure of any household products that will work but if it helps I've used Birchwood Casey products in the past and they work well*.

Duff and Bill are visiting me later this week and could pick some up for you.

In the old dry dock forms someone had used liquid plumber to blacken brass however I never saved the directions, went back sometime ago and the web site was gone. Mentioned this in another thread here but no body commented on it. If anyone has used this method would appreciate their info.

If it really is copper you are wanting to blacken, then use Liver of Sulfur (LOS). Not exactly a household product but easily obtainable online.

LOS has the advantage of being able to be used 'in situ' on the model without affecting the surrounding wood - just wash off the timber. EdT uses this almost exclusively on his Naiad model.
