    Etching Metal

    if you look closely at the raised letters you'll notice where the etchant was able to undermine the mask. This brass plate was made using old technology, today many people are using laser toner for the mask.

    Print on glossy paper then using an iron to transfer the toner.

    There are of course better commercially available products.





    The art of survival is a story that never ends. American Hustle.

    Is that something you do or have done, or is it something you are interested in or collect? I am curious what you would use to etch brass and how long it would take. It would also seem to be a very dangerous process and using very dangerous chemicals that would be hard to dispose of in a safe way. I'm pretty sure that to etch glass they use phosphoric acid, which can burn and also produces very toxic fumes. Is it something safe to do from home of small shop?

    I've made the ferric chloride, the etching is a winter project. I want to replace the stick on plastic sheet on the dash of my small tractor with an etched stainless one. The plastic over the years has shrunk and peeled.

    Having learned about etching how do you know that these brass tags are authentic, I think the Luth Carriage tag is a reproduction aka counterfeit.

    The edges of the lettering are much to crisp.
