A Dramatic Shift

Pier Voulkos boxes

Of all the fabulous polymer clay techniques, which would you say is the most dramatic? There are certainly a lot of them that can be bright and colorful, shiny and sparkling, dramatic and graphic, but could you pick out just one that you think has the most impact when first seen?

I have to say, the one technique that really pops for me is mica shift. It can be colorful, shimmery, and quite dramatic, and has the added effect of looking three-dimensional when it is not. And who doesn’t love a visual illusion?

Mica shift has waned in popularity of late. I’m not sure why because it is just such a gorgeous technique. But when I started researching the idea of making mica shift the theme this week, I found myself on really old posts and pages, looking at work that was created 10, 20 or 30 years ago. That made me all the more determined to bring this technique’s wonderful effects back into the limelight here.

For those unfamiliar with the technique or how it works, here is a little history and explanation for you.

The effect itself is a result of manipulating the mica in metallic clays into orderly layers that you can then manipulate in a controlled manner. This can be done because mica, a shiny, silvery, layered mineral, forms tiny flakes when ground up. The flat side of these flakes are reflective, but the sides are not (like a mirror.) So, if mica is flat side up, it reflects light, but a stack of mica seen from the side is just dark.

You control the mica in your clay by conditioning it in a pasta machine, folding the sheeted clay in half and running it through over and over. The pasta machine rollers, squeezing the clay down, also nudges the flakes to lay flat. Eventually, all the flat faces of all those tiny flakes are facing up in the sheet, causing it to be reflective and shiny.

So then imagine what happens to all those perfectly flat flakes if you press something into them? The flakes get tilted, showing their dark sides (gosh, sounds like some people I’ve known!) That’s where the control comes in. You decide where to distort that perfectly flat sea of face up flakes with a texture sheet, a blade, or hand tools, and where there is distortion, there will be dark outlines of tilted mica. Those outlines are there under the surface too, as the flakes, like tiny dominoes, knock each other over under the invading lines of a texture sheet or a hand tool.

You can also just play with the difference between the shiny surface and the dark sides by stacking mica sheets and cutting it up, rolling sheets into a cane, or twisting or folding a narrow stack, just to name a few approaches. In these cases, the sides of the original layers stay dark and the surface stays shiny, so you have dramatic contrast.

Mica shift in polymer has been called by other names over the years. One of the original innovators of this technique, Pier Voulkos, (those are her boxes opening this post) called it her “invisible caning”. Later, Karen Lewis referred to Pier’s technique as chatoyant, a French term meaning to shine like a cat’s eye, which is used in gemology to describe the bright reflected bands of light caused by aligned inclusions in a stone. That’s certainly fitting for polymer mica shift too.

Let’s take a look at some truly dramatic and lovely examples of this technique.

Shifty Ideas

Around the same time period that Pier was experimenting with her invisible canes, Mike Buesseler was playing with mica clay sheets and “ingots”, stacking then cutting, twisting, texturing and curling up sections of these sheets and ingots to create beads and surface design.

Here is a beautiful necklace using a very simple technique of twisting a square strand of stacked mica sheets.

I would explain more about Mike but, instead, I’m going to let him explain for himself in what is, to this day, the best video class that I have ever viewed. No joke. I’d rather you stop reading this post and watch that video, if it’s all you have time for today. The video is well over an hour-long and it is twenty years old but, no matter how long you’ve been working with polymer or how much you think you know about mica shift, it is well worth your while. It also has an interesting little story about how it came to be a free master class for all. Check it out on YouTube here.

Grant Diffendaffer has long been my polymer clay hero. His mica shift and designs are breathtaking. Although he worked with techniques derived from all the early developed mica shift techniques, his most impressive are his impression pieces. This type of mica shift, sometimes called “ghost shift”, is created by impressing a texture into a sheet of well-conditioned mica clay and then the raised layer of clay is shaved off with a very sharp tissue blade making a smooth surface but leaving the illusion of dimension. Grant created his own texture sheets and then applied them to mica clay Skinner blends. His choice of blended colors surrounded by textured black makes for some very dramatic pieces.

Some of the most dramatic and graphic mica shift you’ll see to this day comes from the studio of Dan Cormier. A lot of his effects come from cutting and puncturing straight down through the clay. When using a blade, the clay shifts only in the cuts where the blade separates the clay causing just a hairline distortion and thus, very thin dark lines. Puncturing shifts more clay as the tool pushes clay aside to get through. The advantage of these distortions, however, is that the design is present and consistent all the way through the stack.

Here’s another take on mica shift from my own table. These gauge earrings might seem a bit more shimmery than a lot of mica shift as I add plain mica powder (bought from handmade cosmetic suppliers) and translucent clay to my metallic polymer clay to bring up the shimmer a notch. These are created from Skinner blend sheets that were stacked, twisted, and rolled smooth before curling them up. They also receive a lot of denim buffing. My mica shift effect is actually the same basic technique that Mike used for the necklace you see above but I twisted it tighter and rolled it smooth with an acrylic plate.

Just so you know, 3 of the artist’s mentioned here no longer work in polymer clay which is why you aren’t getting the abundance of information and links I can usually offer. Pier, Mike and Grant are all multi-disciplinary creatives who moved on to another creative form—Pier returned to dancing, Mike to music and Grant has stayed in crafts but has been exploring a variety of materials and forms. Regardless, we can sure be grateful for their time with us!

Curious Shift

If this little discussion of mica shift has you anxious to get to the studio table and try it out, I heartily encourage you to do so. In fact, I would like to challenge you all to create a little (or a lot) of mica shift this week. I’m going to do the same, creating some new designs with ideas I came up with after researching this post. I’ll share what I’ve done next week and post them to my personal Instagram page.

Do you think you can you get in one mica shift project before the end of the week? Try it and then please send me a photo or link you would be willing to share online, and I’ll see what I can share at the end of next week’s post. You could also just post to Instagram and tag with #polymerartschallenge or message me on Facebook at The Polymer Studio page or write back if you’re getting this by email.

If you have some great mica shift pieces to add to the discussion, leave a comment at the end of the post for us to check out.

And with that, I have to run. Its been a crazy week. There were some problems with production  and getting Issue #2 of The Polymer Studio wrapped up (the release for the new issue will be in a couple of days, April 30th, so keep an eye out for it in your inbox, if you have a digital edition coming, and your mailbox in the weeks to come. Or subscribe or order the issue on our website!) and then we’ve been having problems with the city getting our plans through so we can move forward with the renovations here at the house (many people are still rebuilding from the huge fires we had in November, so they are busy beavers at the planning offices) but, finally, the demolition begins tomorrow and there is still a last few things to prepare. Good news though … we put the refrigerator on the porch instead of in my studio! Yay! We moved the liquor cabinet in here instead. MUCH better idea. I think. Or will it be weird that I can pour a glass of port without leaving my chair here? Well, we shall see.

Until next Sunday my dear readers … have a wonderful week!
