This sculpture is of a robot pushing a button on a sign that says "Don't Push." I used the lost wax technique of bronze casting which I made during a bronze casting class.

The metal portion of the sculpture is made of 2 cast parts welded together: the robot and the sign. Originally, they were one part, however, when I broke open the mold, I found that only the base came out. I re-sculpted and recast the robot during the second pour. After chasing and cleaning both the robot and base using wire brushes (which wore out quickly), I got help welding the feet of the robot to the base.

I added a light liver of sulfur patina on the sculpture to change the color. If I remember correctly, a patina is a chemical that causes a controlled oxidation of metal to color and prevent the metal from oxidizing in an unwanted fashion.

I am quite pleased with the result, considering this was the first time I did bronze casting.
I will try to post some more photos of this piece when I find them.

Some people have asked me if this is an allegorical sculpture, but I assure you it isn't, as Al Gore has nothing to do with it.
where did you get bronze casting class???<br>if there is a metalworking class sign me up!
It was part of the outreach program at the nearby community college.
so cool!
This is really cool!
Thank you!<br><br>Don't forget to rate (if you want to, that is)!
Thanks, I rated it 5*<br>
I'd love to see a step-by-step of how you made this, from sculpting, through casting to patination.<br><br>
I'm not sure I have enough photos to do it. I'm going to have to dig around a bit. I don't like Instructables that just describe a process. I like to see the process as well.<br><br>I was thinking of doing a series with these robots, but that would have to happen next year.
You could visit the foundry and take photos of other people doing the same thing, to fill in the gaps?<br><br>
Actually, I probably have some photos of other people doing their bronze work.<br><br>I'll see what I can do.
I second this, maybe some sort of- dare I say it- Instructable?
