Friday -
I am currently gearing up for Silver Hammer (an SCA Event ) at the end of October. I am getting inducted into the Order of the Pelican, (this is an award given for outstanding service and dedication to the SCA.) In preparation for this I decided to make myself a circlet with nifty designs on it. I’ve taken a metal etching class … and I thought cool this would be a great chance to try out a new project.
Preparation - I drew up a design I liked. I then scanned it and darkend the colors to true black and white. Then I cleaned up the edges. I then printed it out onto Circutboard paper using a laser printer. (Make sure that the printing is on the dull powdery side not the shiny side). I bought the brass plate at Jerry’s Art O’Rama. Betty got the Silver from the Rio Grand Catalog.

Step 1 Clean the Brass – I cleaned the brass with a soap/baking soda mix to get it really, really clean so that water was sheeting.
Step 2 Design transfer – I then took the circutboard paper with the design on it and cut it to fit the brass plate. I taped the paper (dull side to brass, shinny side up) to the clean side of the brass plate using scotch tape. I then took my craft iron (it’s important to NOT use your good iron for craft projects or you will end up going to iron your favorite white shirt and discover that a bit of tape or goo has gotten in your iron and is now all over your favorite shirt.) I used an oven thermometer to measure the iron temp and the dry silk setting got it to ~220 which was a little cool but it worked. Once the iron was at temp I wedged the iron in a shallow drawer so that it had the hot surface up and flat. I the put the brass plate flat on the hot surface. (I would highly recommend getting a vice to hold your iron, I didn’t have one so I didn’t use one, but it would make this step soooo much safer.) I used paper towels to hold the hot brass like a pot holder. I used another couple of paper towels to rub the blue paper. This can take up to 5 min. It’s kind of like watching a photo develop because the black design becomes much clearer as the paper heats. The ink “melts” and is transferred to the brass. When I thought that the design had transferred I pulled up a corner and checked. (It’s easier to check a small corner than to pull of the entire sheet only to discover it’s not quite done yet and try to realign everything.) It had in fact finished transferring to the brass so I took it off the iron and put it on a rack to cool.
Step 3 – prepping Plate for Etching.
Once the plate had cooled I peeled off the blue circutboard paper. The black ink stayed in place on the brass. I then took nail polish and went around the edges of the plate. I took a paint pen and filled any spots in the design that looked thin. I took duck tape and covered the back of the brass plate. I took some foam blocks and hot glued them to the back of the plate. (To act as a handle and float for the plate during the etching.)
Step 4 – I took a big disposable plastic tub (like gladware) and poured in Ferric chloride. (This was the left overs from my previous etching class.) I had probably an inch in the tub. I then put in the brass plate with the float and it floated with the plate submerged. I then let it sit outside for 5 hours. I went out and rinsed the plate with clean water every 30 minutes to get the crud out of the nooks and crannies. Normally this only take 3 hours but I was using ferric chloride that had already etched 2 smaller plates and I was trying to remove a lot of brass.
Step 5 – Neutralization
I took the plate inside and covered it and the float with baking soda. Baking soda neutralizes the Ferric chloride. I then took the left overs in the pan and poured them back into their original container. I marked it as having been used and noted that it probably was good for ~ 2 more plates. I then washed out the container with a baking soda solution. (I marked it Crafts Only with a sharpe so that no one would put food in it by accident.)
Step 6 – Clean up
Once the ferric chloride had been neutralized I used more baking soda and dish soap to clean the plate. I removed the nail polish and ducktape.
I think that the plate came out really well. I’m looking forward to roll pressing it with the sliver.
