Ceramic tile evolution

 

Originating in the Middle East, the earliest evidence of ceramic tile art decorations dates back to Ancient Egypt to around 4,700 BCE. There have been further findings of enamel tiling uncovered in what was Assyria (near ancient Nineveh) and Babylon; these date back to the 7th Century BCE. The art of tiling finally spread further west, becoming popular in Europe during the eleventh century, when mosaic floorings and panels became prevalent. At first it was used to decorate and adorn their churches and other religious establishments. Then much later it was used by the wealthy to decorate and beautify their homes. The Spanish and Italians made beautiful and elaborate designs in numerous geometric shapes and sizes, examples of which can be found in Spain at the Alhambra palace and also the Great Mosque in Cordoba.

The Islamic potters, led by the Persians, revived an ancient Egyptian technique, in which an artificial body material was made up from ground quartz with a small admixture of white clay and glaze. The soft paste body was then covered by thin alkaline glaze. The ‘frit’ body was white translucent when thin and capable of a wide range of decorative techniques. The tiles and wares had a fine white body, unequal to porcelain only in its softness, and a close-fitting brilliant glaze that allows a vibrant range of colors.

The invention of under glaze painting, however was very significant for the history of ceramics. The under glaze painting technique required a glaze stable enough to prevent the pattern from blurring during firing; it was discovered in the use of the virtuous alkaline glaze coating (formulae unknown). For the first time the potters were able to paint freely directly on the frit body under a protective layer of glaze. The new alkaline glaze enabled the artisan to decorate the ‘frit’ ware with precision and delicacy. Also this technique did not have the disadvantages of the earlier lead-glaze wares, which involved great expense in fuel and labor.

The main reason to use alkaline glazes is their ability to enhance and change the properties of coloring oxides in the fired glaze. When fired correctly, these colors have a brightness and clarity that is hard to match. Interesting color changes include:
  • Copper giving turquoise blue (but overfired can go green or even brown)
  • Cobalt, used in conjunction with magnesia, can give pinks and purples
  • Iron giving blue

The Dutch arrival on the scene in the 17th century was very important to the development in the European tile production. It came about when the Dutch East India Company began importing Chinese blue and white porcelain ware into Holland, which became very popular, so they set up a factory to try to imitate the Chinese porcelain, but their efforts failed. However, they were able to arrive at a very high quality earthenware, which became known as delft blue. Eventually an international market was developed and delftware was exported throughout the world.

The Spanish and Italian Majolica tradition, (mainly used as floor tiles until its durability began to be questioned, was then applied to the walls instead) and the Dutch delft tiles, all have a very important place in the history of European tile production. Britain’s arrival on the tile production scene was comparatively late. However, when they arrived they established factories in two English cities, York and Winchester, where they began to mass-produce ceramic tiles, which brought about a reduction in price, making it more widely available and affordable.

Handmade tile art can be truly timeless and contribute to exceptional interior design elements. Some tiles themselves are free form – not square or rectangular as one would expect. Often the shapes are subtle representations of the subject itself. These works are tactile, one wants to touch them and feel their shapes and brilliant colors.

Developing Great Post Reduction Effects on Your Raku Pottery with Peel Away Slip

by Belgium potter Wally Asselberghs .


A finished naked raku fired piece by Wally Asselbergh, showing the variety of grays and blacks he achieves through the use of both diluted and thick glaze and varied application methods over the base resist slip.

Slip-resist raku (also referred to as “peel-away slip” and “naked raku”) is a raku technique in which a slip, which is is formulated to not permanently stick to the surface, is applied to a bisque fired piece before the raku firing. During the firing, the slip shrinks and cracks and breaks away from the piece allowing interesting and irregular smoking patterns to develop from the post firing reduction.

In today’s post, an excerpt from the May/June 2011 issue of Pottery Making Illustrated, Wally Asselberghs explains his techniques for using slip resist to decorate his pottery. He also shares the slip and glaze recipes he uses in this process.

Remember, as with any firing process, especially those that involve an open flame, you should wear protective clothing and exercise all fire-safety precautions. -Jennifer Harnetty, editor.


I fell in love with naked raku in 1995 while attending a workshop on primitive firing techniques by Dutch potter Margot Spiegel Kramer. This was a crucial moment in my life with clay, which at that point seemed to be blocked in a dead-end street. It soon became obvious that this new discovery evolved into a turning point for my ceramic work. New forms started to interact with previously unknown methods of treating my surfaces, painting the canvasses of my forms with fire and smoke.

The balance between maximum possible control of the firing process and the surrender to the fire, and the combination of the expected and unexpected originally attracted me to naked raku. Now, many years later, discoveries and variations keep opening up, allowing me to explore new paths that were previously hidden.

Artistic Perspective

In my organic objects, I try to find a visual language in which my favorite forms (animal, human body, rocks) are reduced to their simplest essence and purity, exhibiting marks as if left by forces of wind and water. On another but equal level, the surfaces of these forms are treated like a canvas. The viewer’s eye meanders between white spaces and black marks left by the fire and reduction techniques of the naked raku process.

Technique

For my clay body, I use commercial cone 10 stoneware clays for black-and-white objects, and low-temperature red earthenware clays for black-and-orange pieces. Both the stoneware and earthenware contain at least 15 to 20 percent fine grog. Most of my objects are constructed with coils.

To obtain smooth surfaces, I’ve always preferred burnishing, as this method gives me the kind of satin matt subtle shine and depth-of-view that I’m looking for. My burnishing tools include credit cards, light bulbs of various sizes and forms, and flat burnishing stones for the final finish.

The Slip Layer

I use a sacrificial layer of slip as a separation between the bisque and the glaze. After the firing, this layer can be peeled away, revealing the pattern on the surface of the pot. The sacrificial slip can be brushed, sprayed, dipped, or poured. Each method has its pros and cons. Differences in application all influence the thickness of the separation layer.
Slip Layer
Pouring has always been my personal favorite application method because it gives me the best possible control over the correct thickness, and the application also goes very fast. If the form allows a good grip, this pouring can be done in one single movement, turning the object from extreme left to extreme right with one hand, while pouring the slip with the other hand (figure 1).

 

The Glaze LayerFor the glaze, my best results have always been obtained with the “classic recipe” formulated by Will and Kate Jacobson

Full glaze layer

The application of a full glaze layer over the slip (figure 2) results in a uniform crackle patterned surface. While this can be perfect for some forms, others may need more. A wide spectrum of other methods for partial glazing can be applied, resulting in a more varied surface. The methods you develop will depend on the results you want. Pouring, masking tape patterns, wax resist, latex, etc., all allow full control over the design.

In addition to using brushes for painting glaze on top of the slip layer, they can also be used to actually splash, flick or spatter the glaze onto the pot from a distance, without the hairs of the brush touching the surface (figure 3). This has grown into one of my preferred techniques. Best results are obtained with a very thick glaze. Large brushes create large areas, while very thin brushes can create fine lines. The amount of glaze on the brush strongly influences the result, as well as the force of the wrist when brushes are shaken to release their load of glaze.

Full glaze layer

While experimenting, splashing on thinner glaze on slipped test-tiles, I discovered that I was obtaining grayish surfaces. I then started fine-tuning and developing this process by making multiple batches of glaze with increasing amounts of water added to the basic mixture. Different bottles, each containing 100 grams of dry materials, were filled with water quantities of 200g, 250g, 300g, and so on, up to 450g. When applied and fired, these diluted glazes created a very interesting and diverse palette of light and dark grays in between the whites and blacks.

When working with these thinned glazes, I often overlap poured areas and apply splashed thick glaze with fine brushes on top of this to create wild patterns. A serious drawback to this method is that the slip tends to carbonize very heavily during the firing, and needs a long soak in water followed by a lot of scrubbing to remove. The eggshell-thin glaze layer will also be nearly invisible, which makes it more difficult to judge the correct temperature by eyesight at the end of the firing.

Note: A very specific feature of naked raku pots are little “black dots” on the fired surface. They usually enhance the total picture, but an overload can be too much. The dots are caused by air bubbles, either in the slip or the glaze. Larger air bubbles can be paddled to the side in the slip or glaze container, but smaller ones may remain unnoticed. When using a drill or a paint mixer to prepare or mix up the buckets, microscopic air bubbles are created. In this case the mixture should be allowed to settle for 24 hours then remixed with a wooden stick before use.

Dust also contributes to the appearance of dots by keeping the slip from properly adhering to the surface of the pot. If you’re trying to minimize the dots, clean the bisque ware with forced air and then with a damp sponge prior to applying the slip.

Kilns

During numerous workshops, I’ve been able to experiment with a wide variety of raku kilns, ranging from huge furnaces to small garbage-can kilns. One of my all-time favorite kiln types is a refurbished old electric kiln. Removing the elements and electric wirings, and cutting a burner hole and a flue exit is all it takes to make a very cheap and dependable kiln.

At home I also have a top-loader kiln based on an empty 200 liter drum, lined with 2 layers of 2-inch thick low-temp ceramic fiber. Before buying a Ward burner, I have fired this kiln for years with a simple and cheap weed burner, the type also used by roof workers, which also gave excellent, if noisy, results.

Firing

As with standard raku, preheating is also very important for firing naked raku. Though moist objects can be preheated slowly in the first kiln load with a minimal risk of breakage, any consecutive firing schedule makes preheating absolutely necessary. Even if dried in the sun, some moisture will always remain in the bisque ware, quickly changing into steam when placed in a red-hot kiln, causing explosions.

Raku firing

During workshops, when the size of objects is usually quite small, I use 2 different methods, depending on the material available, and expected weather conditions. The easiest way to preheat is to use a large electric kiln, positioned to maintain a constant temperature of 100°C (210°F) and preheat the bisqued objects for 20 minutes. If no electric kiln is available on site, I use one or more large barbecue grills, aiming for a 20 to 30 minute drying schedule, depending on size and thickness. Once the piece is dry, fire it to the temperature required for the glaze to reach an orange-peel texture. Remove the piece from the kiln using raku tongs (figure 4).
Post Firing Reduction

In standard Western raku, objects are sometimes buried in massive quantities of fine sawdust. For naked raku, the use of sawdust generally results in excessive reduction, especially when using diluted glazes. For best results, my favorite reduction materials are curly wood shavings or very thin wood chips. One good handful, sprinkled on top of the pot, is usually more than sufficient (figure 5).

There are many theories about how long objects should stay inside the smoke bins, but I experienced that the time interval is rather flexible. In general, 5 to 6 minutes are considered to be a minimum, as most of the reduction process generally takes place within this time frame. During workshops, and for my own work, I generally leave them in for 10 to 12 minutes. The extra time assures a complete reduction and, as objects continue to cool down, also reduces the risk of cracks appearing.For larger monumental work, or fragile objects constructed with plates or slabs, it’s safer to go for 20 or 30 minutes, or even up to one hour. However, the drawback is that prolonged smoking may change the color of some clays from white to buff, or even light gray. Regardless of the time frame, cover the reduction chamber with a lid, and wrap a wet towel around it to keep the smoke from escaping (figure 6)

Removing glaze layer

After firing, begin to remove the eggshell-like layer of glaze (figure 7). All objects need additional scrubbing, using plenty of water, to remove all traces from the firing, and residual fragments of the remaining slip and glaze layers. When using diluted or splashed glazes, some areas may be very hard to remove, and should be soaked in water for many hours, sometimes overnight.

Conclusion

Most of the forms and canvases of my sculptural ceramics relate to changes. Some works relate to the moment that water changes into ice, or starts to evaporate into steam. Others try to capture the nanosecond when a plane is shivering between air and soil, or try to evoke a build-up of pressure, that precious moment just before an explosion renders a piece into shattered fragments.

Life has always been about changes. If that is true about life, that is, to me, what my ceramics are about. Like the alchemist in medieval times, I try to manipulate the untamed metamorphosis during the process of firingceramic materials into another dimension, the ultimate amalgamate of substance and dreams of mankind.
