Not quite as time consuming as writing in stone, but equally indelible: etch your own art in precious brass! The concept is pretty neat: circuit board etching acid eats away at copper and copper alloys. This means that it will eat away at brass, but it's mojo technical term is interrupted by the presence of iron. By adhering iron to a plate of brass by way of the iron oxide found in printer ink, we can etch any 2D pattern into our plate. Start by meticulously cleaning your brass plate.

Any size plate will do, and the acid bit to the tune of. I cleaned mine with a Scotch Brite pad, and then wiped it off with acetone until my rag stopped pulling off dirt. This whole process requires high contrast printouts from a laser jet printer.

I've been experimenting with different methods, and have found that transparencies get a really good resolution, but I believe that printing out on parchment paper would work even more smoothly. Anyway, the process is that after you print your image greyscale just doesn't cut it, if you want a tonal range, use a halftoneyou lay the sheet print side down on your brass and iron it. I put my iron on its highest setting, with no water in it, and press on the image in patches.

I press down fairly hard for about thirty seconds, and move up the image in this fashion until the whole image has been covered. If you don't have transparency paper the process will still work with regular printer paper I just don't have the patience to do it right. After letting the plate cool from ironing, you can soak it in a bath of warm water to loosen the paper away from the printed area now stuck to the brass.

With gentle rubbing and a good long soak, most of the paper will come off, leaving you with a pretty clear pattern.

I just said hang the wait and tore the damn thing off. I then carefully lifted the transparency away and Viola De Gamba! I've used Jameco's powdered etching solution and it seems to work well, though, I believe that you could use any circuit board etchant. It is at its strongest when warm, and works fastest if you agitate the bath while it etches.

I suggest you go to the hardware store and pick up some chemical-resistant gloves and a plastic bus tub as I've got here. This plate spent ten minutes in the tub and came out well, but I bet a longer soak would have done much better. Remove the plate when you feel like it's done its job. It's best to experiment with a couple small test pieces before going for something large and expensive.

After the etch is complete, scour the plate with a ScotchBrite and admire your work. You could use some black primer on the plate and buff it again to bring out the pattern in higher contrast. Below, you'll notice both the etching shown in the tutorial, and an earlier test. Things I'll try for next time: Longer exposure time with acid, as well as a method for heating and agitating the solution Transfer from parchment paper Etching for a massive amount of time to see what happens While I'm here, I'd like to give some thanks to Michael Glancy, the super awesome electroforming ninja who suggested that I explore etching.

Hi, I've tried transferring my image to a copper plate using this method several times without success. I'm using transparencies, but I just can't get the image to adhere to the plate except in bits and pieces. Do you have any suggestions? Hi, I'm trying to follow your instructions but having some trouble.

I'm using transparencies like you suggested, but my images are not transferring well at all, even though I've spent close to an hour going over them with my iron. I also notice that in your picture, it looks like you are using some sort of paper, not a transparency. Can you give me a brand name or some othr info on how to get the image on the copper?

If I'm understanding this correctly, you are etching everything that isn't the pictures because you didn't do a negative image of what you want? So the whole board is reduced, except for little ridges that stand up that are the lineart? Doesn't that take a lot of etching solution? Reply 14 years ago on Introduction. You've pretty much got it. From my one batch of etchant about one pint I've etched two plates of this size and a couple other smaller ones.

I think your pictures should be facing down because the acid works with the help of gravity. Daax krazy Reply 13 years ago on Introduction. After you're sent to the top, scroll down to the step the picture was at.
