Talavera pottery is a Mexican and Spanish pottery tradition named after the Spanish Talavera de la Reina pottery , from Talavera de la Reina , in Spain. The Mexican pottery is a type of majolica faience or tin-glazed earthenware , with a white base glaze typical of the type. Production of this ceramic became highly developed in Puebla because of the availability of fine clays and the demand for tiles from the newly established churches and monasteries in the area. The industry had grown sufficiently that by the midth century, standards and guilds had been established which further improved the quality, leading Puebla into what is called the "golden age" of Talavera pottery from to It is a mixture of Italian, Spanish and indigenous ceramic techniques.

When I was taking my first wheel throwing class, I remember staying in the studio late one night centering clay over and over again. Once I got centering mastered, I remember getting super frustrated because I kept throwing the clay off center when I tried to open it.

Then, of course, there was the struggle to pull nice even tall walls. Sound familiar? The cross section photos should be a helpful guide for beginners out there and those who teach them. After the clay mass is well centered and wheel-wedged, you are ready to begin forming a vessel. With the wheel still running at high speed, lubricate the spinning lump, wrap your hands around either side for stability, and with the tip of one thumb create a dimple in the center of the top.

When working with a small lump of clay, squeeze some water into that dimple, and simply continue pressing the thumb down into the lump, creating a narrow V-shaped opening in the center of the lump.

When working with a larger lump, after squeezing water into the dimple slowly press one finger of your left hand the second finger with the index finger twisted around behind it to back it up works very well down into the center of the lump, holding the finger at a slight angle, and keeping the fingertip right on the center axis as you press down, again producing a V-shaped hole. Keep your right hand wrapped around the right side of the lump for stability, and use the left side of your right thumb as a steady rest and guide, sliding the fingers of your right hand against it as they penetrate the lump.

The decision of how thick to leave the bottom of a pot depends on whether or not you plan to trim away any clay from the bottom. Until you develop an accurate sensitivity to bottom thickness, it is worthwhile to check it at this point.

Hold your needle tool in one hand with the index finger against the base of the needle. The distance between your fingertip and the end of the needle tool gauges the thickness of the bottom. You can use this system whenever you wish during the throwing process to measure the thickness of the bottom of a pot.

Slow the wheel down a bit for this operation. As your skill develops, you may wish to do the penetrating and claw widening steps in one continuous movement with the wheel at high speed.

Squeeze water from your sponge over the spinning lump so that it flows down over the inside and outside walls. As you widen the bottom try to keep it as level as possible.

If you end up with a concave cross section across the bottom it is because you are lifting up your fingers as you widen the bottom. Avoid both these circumstances, trying instead for a flat uniform bottom. There are circumstances where you will want a curved bottom, but for the sake of skill development it is good to work on creating uniform flat bottoms.

In my experience, if initial centering, wheel wedging, penetrating, and widening are done correctly, recentering usually is not necessary.

When you widen the bottom you are pulling clay away from what remains as the bottom of the pot, whereas during subsequent lifting you will be compressing the walls of the vessel from both sides. If the bottom remains uncompressed, it will shrink more than the walls, and S-shaped cracks may form during drying or firing.

To avoid this, apply mild fingertip pressure against the spinning bottom, moving from the center to the right edge and back again several times. This is also the ideal time to level any irregularities in the bottom. Clay: A Studio Handbook , by Vince Pitelka, one of the foremost authorities on studio pottery, is now back in print!

Check it out! If all has been done correctly up to this point, you are at what is called the doughnut stage, ready to begin lifting the walls. Hold both hands as you would to shake hands with someone. Bring them together, and cross and lock your thumbs together, creating what we call the caliper position. Bend your fingertips slightly inward. If you bend them too much you will rake clay off the surface, and if you bend t hem too little you will be working with the flats of your fingers and will have little control.

With your hands held in this caliper position, you have formed both a lifting tool and a measuring device, and during the lifting process it is important to always think of your hands as not only moving and thinning the clay, but also constantly gauging the thickness of the walls. It will feel awkward initially, but you will get used to it quickly. While undertaking the lifting process, keep your elbows resting on your thighs or tucked in against your torso for stability. When you have experimented with this position, bring the wheel to medium speed and squeeze your sponge above the rim of the spinning vessel so that water flows down both inside and outside.

From this point on, always work on the right-hand side of the vessel, where the clay is moving away from you. During the very first lift, the wall at the base of the vessel will be considerably thinner than the doughnut above it, so do not apply significant pressure until you come up against the doughnut, but at that point increase the pressure and continue lifting.

The most common fault at this point is to apply too much pressure beneath the doughnut, so that the lower walls are thinned too much and no longer have the strength to withstand the torque necessary to thin the walls above. As you lift, your fingertips should leave very gradual spiral marks up the side of the vessel. Stop just short of the lip of the vessel.

Always lift in one continuous pass from the bottom to the top, and between each lift always squeeze more water over the rim with the wheel spinning. Stop each lift just below the rim, and do not allow your fingers to slip off the rim, as this will distort it badly. In each lift after the first one be sure you apply pressure right from the bottom, in order to maintain even wall thickness, but try to avoid making the walls too thin anywhere.

To measure the thickness of the walls, hold your needle tool in your right hand as you did for measuring the thickness of the bottom. Hold a finger of your left hand against the inside wall where you want to measure thickness.

At the corresponding spot on the outside, poke the needle tool through the wall until it barely touches your finger on the inside. Complete the measurement just as you did in measuring the thickness of the bottom.

If you find that you are ending up with wide bowl-like cylinders, then you need to concentrate on keeping them narrow. Centrifugal force tends to direct the clay outward from the center, and you must counteract this. When you are lifting, think of your hands in the caliper position as a single tool. As you lift the walls, you must purposefully direct that tool inward towards the center axis of the pot, resulting in a tall tapered cylinder.

Poke your needle tool into the bump. If the needle goes right through, it is probably an air bubble. When you do your next lift the air will squeeze out through the hole left by the needle tool. If the bump is a foreign object, then you must decide whether to leave it or remove it.

If it is very small you may choose to ignore it, but if it is large you can remove it and press a small piece of clay into the hole. Check out this awesome tip for cutting the pot off the wheelhead!

Some potters prefer to use a water based wax which has the advantage of not requiring heat nor smelling strongly as paraffin does. Other potters just wash the glaze off the bottom of the pot. If the pot has a lid, such as a casserole or bean pot for example, we apply a wax emulsion. This keeps the glaze from the lid and pot. Glaze can be applied by several methods but we prefer to dip our pots into a container of glaze. Next, using dipping tongs the pot is totally submerged in glaze, lifted out and set aside until it dries.

Once the pot is glazed, it is returned to the kiln for a second firing, in which the clay and the glaze are matured,. In the case of our pots which are fired in an oxidation environment in computer controlled electric kilns this temperature is. This final temperature is decided by trial and error and is again influenced by the nature. Kilns can be fired to cone or temperature. We have our own firing schedule which allows us to fire to temperature over a specified time in controlled increments.

After achieving the desired temperature the pots are allowed to slowly cool over the next 24 hours. In some ways every time is like the first time as the "Kiln Gods" can sometimes really surprise you. The finished pot is then given a final sanding and dusting before being packed for shipping.

Every potter has his or her own formulation for glazes and many of these are a closely guarded secret as the unique properties imparted by a particular glaze fired on a particular clay body, combined with the characteristics of the design of the piece are what identifies the pot as belonging to a certain potter.

Talavera pottery is a Mexican and Spanish pottery tradition named after the Spanish Talavera de la Reina pottery , from Talavera de la Reina , in Spain. The Mexican pottery is a type of majolica faience or tin-glazed earthenware , with a white base glaze typical of the type. Production of this ceramic became highly developed in Puebla because of the availability of fine clays and the demand for tiles from the newly established churches and monasteries in the area.

The industry had grown sufficiently that by the midth century, standards and guilds had been established which further improved the quality, leading Puebla into what is called the "golden age" of Talavera pottery from to It is a mixture of Italian, Spanish and indigenous ceramic techniques.

The tradition has struggled since the Mexican War of Independence in the early 19th century, when the number of workshops were reduced to less than eight in the state of Puebla. Later efforts by artists and collectors revived the craft somewhat in the early 20th century and there are now significant collections of Talavera pottery in Puebla, Mexico City and New York City.

Authentic Talavera pottery only comes from Talavera de la Reina in Spain and from the town of San Pablo del Monte in Tlaxcala [5] [6] and the cities of Puebla, Atlixco, Cholula and Tecali, as the clays needed and the history of this craft are both centered there. All pieces are hand-thrown on a potter's wheel and the glazes contain tin and lead , as they have since colonial times.

This glaze must craze , be slightly porous and milky-white, but not pure white. There are only six permitted colors: blue, yellow, black, green, orange and mauve, and these colors must be made from natural pigments. The painted designs have a blurred appearance as they fuse slightly into the glaze.

The base, the part that touches the table, is not glazed but exposes the terra cotta underneath. An inscription is required on the bottom that contains the following information: the logo of the manufacturer, the initials of the artist and the location of the manufacturer in Puebla. The design of the pieces is highly regulated by tradition.

The paint ends up slightly raised over the base. In the early days, only a cobalt blue was used, as this was the most expensive pigment, making it highly sought after not only for prestige but also because it ensured the quality of the entire piece.

The process is risky because a piece can break at any point. This makes Talavera three times more costly than other types of pottery. Guanajuato state petitioned the federal government for the right to share the Talavera designation with Puebla , but, since , this has been denied and glazed ceramics from other parts of Mexico are called Maiolica or Majolica. Today, only pieces made by designated areas and from workshops that have been certified are permitted to call their work "Talavera.

Each of these needs to pass a twice-yearly inspection of the manufacturing processes. Pieces are subject to sixteen laboratory tests with internationally certified labs. The process to create Talavera pottery is elaborate and it has basically not changed since the early colonial period when the craft was first introduced.

It is then washed and filtered to keep only the finest particles. This can reduce the volume by fifty percent. The initial glazing, which creates the milky-white background, is applied. After this, the design is hand painted. This process is so complicated and plagued with the possibility of irreparable damage that during colonial times, artisans prayed special prayers, especially during the firing process.

Some workshops in Puebla offer guided tours and explain the processes involved. The oldest certified, continuously operating workshop is in Uriarte. Talavera ceramic is mostly used to make utilitarian items such as plates, bowls, jars, flowerpots, sinks, religious items and decorative figures.

However, a significant use of the ceramic is for tiles, which are used to decorate both the inside and outside of buildings in Mexico, especially in the city of Puebla. It is a very distinct style of kitchen. In monastery kitchens of the area, many of the designs also incorporate the emblem of the religious order. This led to a saying "to never be able to build a house with tiles", which meant to not amount to anything in life.

What makes this palace, in the City of Palaces, distinct is that its facade on three sides is completely covered in expensive, blue-and-white tile — sensational at the time the tiles were applied. Techniques and designs of Islamic pottery were brought to Spain by the Moors by the end of the 12th century as Hispano-Moresque ware. From there they influenced late medieval pottery in the rest of Spain and Europe, under the name majolica. Further Italian influences were incorporated as the craft evolved in Spain, and guilds were formed to regulate the quality.

During roughly the same time period, pre-Hispanic cultures had their own tradition of pottery and ceramics, but they did not involve a potter's wheel or glazing. These monks wanted tiles and other objects to decorate their new monasteries, so to keep up with this demand, either Spanish artists or the monks taught indigenous artists to produce the glazed pottery.

From the time that the city of Puebla was founded in , a large number of churches and monasteries were being built. The demand for tiles to decorate these buildings plus the availability of high-quality clay in the area gave rise to the ceramic industry.

It was soon produced by indigenous people as well as Spanish craftsmen, which resulted in a mixture of influences, especially in decorative design.

The new tradition came to be known as Talavera Poblana to distinguish it from that of Talavera pottery from Spain. From to the midth century, the number of potters and workshops kept growing, each having their own designs and techniques. The colonial government decided to regulate the industry with guilds and standards. In , the first ordinances were passed. These regulated who could be called a craftsman, the categories of product quality, and norms of decoration.

Some of the rules established by the ordinances included the use of blue cobalt on only the finest, quality pieces, the marking of pieces by craftsmen to avoid counterfeits, the creation of categories of quality fine, semi-fine and daily use , and yearly inspections and examination of master potters. The period between and was known as the Golden Age of Talavera.

During the Mexican War of Independence, the potters' guild and the ordinances of the 17th century were abolished. This allowed anyone to make the ceramic in any way, leading to a decline in quality. Out of the forty-six workshops that were producing in the 18th century, only seven remained after the war. Ventosa was fascinated by the history of the craft which was unique from other art forms in Mexico. He studied the original processes and combined it with his knowledge of contemporary, Spanish work.

He published articles and poems about the tradition and worked to decorate ceramic pieces. In , he befriended Ysauro Uriarte Martinez, a young potter, who had inherited his grandfather's workshop. The two men collaborated to create new decorative designs, adding pre-Columbian and Art nouveau influences to the Islamic, Chinese, Spanish and Italian influences that were already present.

They also worked to restore the former levels of quality. Their timing was good as the Mexican Revolution had ended and the country was in a period of reconstruction.

However, by the s, there had been a further decline in the number of workshops until only four remained. Since then there has been some resurgence in the craft. In the s, seventeen workshops were producing Talavera in the old tradition. Eight were in the process of becoming certified.

Although the Spaniards introduced this type of pottery, ironically the term Talavera is used much more in Mexico than in Talavera de la Reina, Spain, its namesake. Requisites included the city of production, the clay that was used, and the manufacturing methods. These pieces now carry holograms. However, the tradition still struggles. Angelica Moreno, owner of Talavera de la Reina, is concerned that the tradition of the craft is waning, despite her workshop's efforts.

One problem the craft faces is the lack of young people who are interested in learning it. An artisan earns about to pesos a week, which is not enough to meet expenses. In the early 20th century, interest developed in collecting the work.

She became interested in collecting the works, so she consulted scholars, local collectors and dealers. Eventually, her collection became the base of what is currently exhibited in the Metropolitan Museum of Art in New York. He, too, spent time in Mexico and introduced Talavera into the Pennsylvania museum's collection. He studied the major stylistic periods and how to distinguish the best examples, publishing a guide in which is still considered authoritative.

During this time period, important museum collections were being assembled in Mexico as well. A bit later, in the s, Franz Mayer , a German-born stockbroker, started his collection. In Puebla, he was considered a bit crazy for buying all of the "old stuff" from the locals. In , the Franz Mayer Museum opened in Mexico City with the largest collection of Talavera Poblana in the world — pieces from the 17th through the 19th century, and some 20th-century pieces by Enrique Luis Ventosa. More recently, the Museo de la Talavera Talavera Museum has been established in the city of Puebla, with an initial collection of pieces.

The museum is dedicated to recounting the origins, history, expansions and variations in the craft. Pieces include some of the simplest and most complex, as well as those representing different eras. Several temporary and travelling exhibits of certain themes have been created from these permanent collections. The forty-two-piece exhibit was sponsored by the Senate of Mexico to show how the eagle symbol has been used in the country throughout its history.

This exhibit was sponsored in honor of the Bicentennial of Independence in These ceramics were chosen because of their combination of art and utility.

Another exhibit in Mexico centered on the creation of maps using Talavera tile. Most tiles during the colonial period were decorated with flowers and landscapes but a significant number were painted to create murals with maps. Those that survive show how a number of cities developed over the colonial period. This exhibit was of reproductions of the originals created by the Talavera de la Luz workshop in Puebla. The chosen maps show the development of Mexico City as well as representations of the Acapulco , Puebla and the Tesuco regions during this time period.

Exhibits have been held outside of Mexico as well. This was a temporary exhibit of 49 pieces, combined with pieces from Spain and China as references. From Wikipedia, the free encyclopedia. Main article: Azulejo. Inside Mexico.
