All It’s Cracked Up To Be

What is it about weathered and worn surfaces that so many people find attractive these days? Mind you, I am very much one of them. I have a whole line of work called “Beautiful Decay” that explores the beauty I find in the deterioration of durable materials. But the one related effect that seems to be everywhere these days is crackling. Who doesn’t love a good crackle! From shabby chic furniture to crazed ceramics to crackle glass decor, the look of a deteriorating surface seems to have wide-ranging appeal.

Knowing that, it’s not really a surprise that crackle is so popular as a polymer technique. A great many of us are already texture fiends and, if you love texture then you are going to try crackle- so there’s one of the reasons for its popularity in polymer. But we also know that there is a market for work with crackled surfaces since it pops up in so many areas related to decoration and adornment, making it a safe bet if you sell your work.

There is no one right or best way to create a crackled surface in polymer. You may not have realized it, but there are literally dozens of ways to create crackle. It can be created with a crackle paint medium, partially cured layers of polymer (like I show you in my Controlled Crackle technique which you can find in your Fall 2011 edition of The Polymer Arts), dried paint (or glaze or gilders’ paste or floor wax) on raw clay, metal leaf on raw clay, leaching, alcohol treatments, or by creating a faux texture with impressed materials. And I know I am still missing a few in that list!

So, let’s enjoy some crackle work today and wrap up with a few tutorials on different crackle techniques that you can try out.

 

Let’s Get Cracking

One of my personal favorite “cracklers” is Staci Louise Smith. She uses a number of different techniques to achieve a wide range of cracked texture. In the necklace below, her crackle is not subtle. It is not evenly spread across her beads either but rather, it is rough and tumble and scattered in energetic horizontal lines. Her soft coloring calms the chaos of the crackle which is also balanced out by the many other purposeful accents and lines from the wire.

Staci can also do subtle as evidenced by the opening piece, a Balance Bowl from her tutorial in the Polymer Art Projects – Organic book. (You can get the book on our website if you want to make one of these stunning bowls.)

Check out this blog post where she shares how she makes the necklace here along with sketches and her thoughts on the process.

 

A subtle crackle can often take a bit more patience but what a lovely effect it can have. It may not even be obvious at first that the beads on this necklace below by Ursa Polak have a crackle surface, but the weathered feel comes across immediately. Take a close look to see all the fine-lined cracks that add to the depth and variation of the surface.

 

Kroma Crackle is a lovely gel medium that itself dries and cracks without having to stretch the clay and yet remains flexible so that you can manipulate the clay without the cracked material popping off. Once you worked with it for a bit you can control the size of the crackle pretty well. You can add small amounts of acrylic paint or mica powders to give yourself a wide variety of color options. You can also apply paints, inks, dyes and other colorants on it after its dry.

These earrings are by Els van Haasen uses Kroma Crackle on polymer. You can see how regular a crackle you can get with this medium. But it can definitely be quite varied once you come to understand how to use it.

 

You almost forget that the technique that was most commonly used by the highly esteemed Elise Winters, who we lost just this year, was also a crackle technique. Her work was very controlled, as was crackle but that was probably the most recognizable part about her signature style. I can only imagine the work she put into gaining such control over her crackle, but it just shows what can be done when we invest a bit of patience into our work. (I erroneously put in that this was metal leaf when I first posted but, no, it’s paint, which also takes such skilled control, having to ensure that the paint is evenly applied to get such fine crackle.)

 

This is actually a piece of mine from some years back. It includes alcohol treated raw clay, controlled cracking of partially cured clay, and metal leaf colored with alcohol ink. The alcohol treatment is a way of drying out the surface of raw clay to get a very fine crazing. It’s a bit of a tricky technique but it sure worked here. That helped create the uneven surface of the partially cured polymer under the metal leaf, giving it a burning ember look.

 

Let’s Crack You Up

Ready to try some various cracking techniques? Here are a few freebies to get you going:

If you want to try the straightforward Paint Crackle Techniques:

• Grab a craft acrylic (the cheap acrylics work better than artist tube acrylics which tend to stretch rather than crack) or tempera paint and a well-conditioned sheet of polymer rolled on the thickest setting of your pasta machine.
• Brush a moderate (not heavy) layer of the paint onto the polymer. Wait for it to completely dry.
• Then roll it through the pasta machine set at two settings down from the thickness you created the sheet on. You can stop here or, for wider, more varied crackle, turn the sheet 90°, adjust the pasta machine down another one or two settings and run it through again.
• You should have a nice crackle now but if your paint is stretching rather than cracking, rolling another sheet of polymer and lay the crackle sheet on top and then start rolling it through the pasta machine again. Eventually, the paint will crack but sometimes you need a really thick layer of polymer to start in order to stretch it far enough. Tempera paint won’t stretch and cracks very nicely if you have that on hand or fancy a run to your local craft store. You could also get some crackle medium while you’re out and follow the instructions to crackle paint directly on your raw polymer clay.

You can find some examples of the use of different paints on this post by Jan Geisen.

For more tutorials online:

• One of the things I didn’t show you in the samples above was how to use impression material to create a faux crackle effect. I use crumpled aluminum foil for this and then use the antiquing approach of rubbing acrylic paint into the cracks after its cured and wiping it off. But Katie Oskin has an interesting material to share in this online tutorial, as well as showing the effect of painting it before she impresses it.
• In this video tutorial, Sandy Huntress shows you how to crackle very thin sheets of partially cured polymer clay.
• Crackling can be done on round surfaces too! Here’s an online tutorial using metal leaf on bicone beads to create crackle. Keep in mind you could do the same thing by painting the beads and then rolling them around to get it crack.
