March 8: International Women’s Day

Posted by C Scheftic on 2018/03/08

Kepler's DreamI call this piece Kepler’s Dream, and it’s the one I chose to enter when I was invited to participate in the Cranberry Artists Network‘s show in honor of International Women’s Day.

Now, IWD is March 8, and the show is only being “hung” that evening. The official dates of the show are March 9 through April 5.  It looks like there could be as many as 33 pieces in the show.

There will be a Public Reception from 6 to 8 pm on Thursday, March 22.

Question: Why enter a piece named after Johannes Kepler for Women’s Day?

Discussion: Well, I was in high school when I first learned of his discovery that planets moved in elliptical orbits around the sun (not the earth!) and the sun itself was not even at the center but at one of the two focal points of that ellipse.

That was also when I first heard about his conjecture from the early 17th century on the efficiency of packing spheres. That was not really proven until early in the 21st! I actually worked for a few years late in the 20th century with some folks who were involved in trying to find the proof!

Anyway, the readings I had been inspired to devour back in high school were key to opening my mind to being able to “think big” about the seemingly-mundane topics we were covering in school. Did you know, for example, that Kepler also published the first description of the hexagonal symmetry of snowflakes?! And he looked at the efficiency of hexagonal packing: think beehives! There’s more: go do some explorations of him yourself!

And so after decades of doing formal mathematics using accurate visual representations of what IS, here I am now doing artistic explorations of what COULD BE. I had no thought of Kepler as I began this piece: it would look rather different if I had! (And such a piece in this line will likely come to exist eventually.) But as I finished it, and looked at the combination of shapes I’d created (sort of oval and round), and thought about the colors I’d chosen (with their references to the skies above), and talked about it with some friends I was visiting at the time, I just began to wonder if Kepler might ever have dreamt anything like this.

Answer: So I named it Kepler’s Dream to honor him for being one of the influences (indirectly and centuries later) on this woman’s life!

Also, re technique: If you’re a regular reader of this blog, you may think that this piece doesn’t look typical of my work. And you’d be right! This piece was made using Hadar’s Low Shrinkage Steel (metal clay powder). The back is plain, with just the bail for hanging it. (I do have ideas for other designs, with my usual make-it-reversible approach, but this one was part of the experience of simply perfecting this technique, so I kept it simple!)

After firing so it would sinter, the steel was treated to help it resist rust. Then I applied three different enamel colors into the openings of the embellishments. (Yeah, the mathematician / geometer in me had fun figuring out how to space out three colors among ten spaces, when ten is not an even multiple of three.) Because of the way I applied the enamels, it was easy enough to fire several different colors at the same time; to get good coverage, on the other hand, it took multiple applications of the enamel powders, and re-firing each round, until it came to look like this. As a final step, I applied a light coat of wax which helped to even out the color of the steel and should also help to further protect its finish. I made several others at the same time which I’ll try to remember to discuss in a later post. But I am including a tag with each one warning a buyer that, because steel can rust, I recommend some common-sense precautions: don’t wear it while bathing, showering, or swimming and, if it does get wet, try to dry it thoroughly as soon as possible.

Finally, a big “thanks!” to Hadar Jacobson for the recent workshop and especially for the photo, so I’d have it in time for the show!
