The Rabbitry Plaque
This Plaque was a fun project. I made it for my wife who has a few rabbits that she loves. Any blue words are links that you can click on if interested.
NOTE: Metal casting is dangerous so remember to be safe in all you do and don't blame me if you hurt yourself!
Here is a picture of the paper I started with. I glued this onto a piece of foam and cut it out with a utility knife...because I couldn't find my exacto knife...I hate it when I can't find my tools!!!
Here is the pattern imbedded in my K-Bond sand. The blue rectangle is the sprue and the large hole is a riser. The little holes are lots of vent holes that I put in with a wire. I used oil bonded sand because I have had problems getting a plaque to fill in the past if I just used loose sand.
Here is a video of the pour....PLEASE NOTE! I appologize for my attire...or I should say, lack of propper safety attire...but at least I had my gloves and face shield on!
Here is a video of the shake out.
Here it is after I ran over it with a wire brush
OK Now the interesting part...I played around with some patinas on this plaque. I wanted to put a greenish antique patina on it. So I ordered cupric sulfate and ammonium chloride from science company.com for the antique green number 5 recipe shown on their site. Before I got the chemicals, I looked up some household formulas on the net. This first picture is one that I put table salt and vinegar on it. It made it turn rather blue.
But, My wife didn't like it! Too green! I was afraid of that... so I sand blasted most of the patina off and
re-laquered it. I like it both ways.
Well, that's all Folks! If you enjoyed it...leave a message on this page in the guestbook so we can all see who has been here! CLICK HERE to see my new guessing game site.

Then, I put it in a plastic bag with a cup of ammonia in it and it turned it this nice shade of blue...pretty, but not what I was going for.
I got the chemicals and tried to apply them with a torch and sprayer...It didn't work very well...It just turned black. I think I got the metal too hot. So I put the plaque in the oven and heated the patina on the stove. Then I carried both outside to apply. After two times, I had what I wanted.
Here it is as cut out. I leave the paper on when I put the foam pattern into the sand...It makes a nice smooth surface and the paper turns to carbon.
Here it is after I sand blasted it
I talked to Amy who runs the Home Foundry and Casting group at Yahoo and she suggested using gun bluing for a base before applying the patinas. The next picture is that result. Here it is with the lettering and border shined up and a laquer (increlac) applied.
