"Of all the arts, ceramics is the most fundamentally linked to the physical make up of the planet that we inhabit and best illustrates the link between science and art. It can be seen as an artistic expression of the geology of earth."
— Mattew Blakely, 'ceramic landscapes - the idea'
In addition, ceramic artworks can be thought as geological objects themselves. In the case of Blakely's ceramic landscapes, each piece is entirely created from rocks and minerals collected from individual locations. In more general terms, ceramic artworks are commonly realized with clay, which is the result of geological processes. With the words of Mattew Blakely: "Pots represent our relationship with and dependency on the planet, making things for human use from the dug earth beneath our feet."

Besides Mattew Blakely, several ceramic artists referred to geology in their artworks. Among others, Akiyama Yo titled Geological Age V one of his ceramic artworks; Len Castle's ceramic fossils have been exhibited as Sea Secrets and Searching for Fossils in Gondwana; Ettore Sottsass developed a set of layered ceramics ('geology bowls'); Naomi Teppich realizes ceramic fossils; the creative process of Sally Rockriver is inspired by geochemical processes and crystallization.

In more recent times, fossils inspired Alan Spencer for realizing Strata in Clay, a series of stoneware vessels representing fossil forms through deep time. With the words of the artist: "The stoneware vessels, Strata in Clay, were created as a series to represent examples of the fossil time line that have been preserved in rock strata during the past 500 million years".
I interviewed Alan Spencer, the deep time explorer.
Alan, who are you and what you do?
I was born in Providence, Rhode Island in 1955. I teach ceramics and sculpture as a visual art teacher in the Worthington city schools in central Ohio. When I am not working with students in the high school, I find time to work on my ceramic artwork. Through my recent series of artwork, Strata in Clay, I get to combine the two passions I have in my life, ceramics and geology. Since I was young, I have had an interest in working with clay on the potter’s wheel, and I have been fascinated with fossils.
What career path did you take to get to where you are now?
After graduating from the College of Wooster in 1978 with a major in geology and a minor in
|Alan Spencer, Triassic (from the Strata in Clay series).|
In 1999 I went back to school at Ohio State University to get my teaching certification and my Master’s degree in Art Education. I have worked as a visual arts teacher in Worthington, Ohio since 2002. While teaching in the schools, I continue to create my own style of ceramic artwork, utilizing the potter’s wheel to create the large thrown forms.
How has being a geologist influenced your art and your philosophy of life?
I don’t believe that being a geologist has influenced my philosophy of life, but it has given me avenues of inspiration as an artist. The knowledge I received in college helped me to understand concepts such as geologic time periods and the evolution of life on earth. Studying detailed fossils as a geologist has allowed me to be able to recreate fossil forms as accurately as possible in my artwork.
Your current project is ‘Strata in Clay’: how do you describe it?
The stoneware vessels, “Strata in Clay,” were created as a series to represent examples of the fossil time line that have been preserved in rock strata during the past 540 million years. In each of the geologic time periods, certain life forms have become known as indicator fossils. After the identification of the indicator fossils for the geologic periods was completed, researching, sketching and modeling of the fossil forms commenced.
Replicas of the fossils from each of the twelve geologic periods were sculpted and fired, creating a mold that could be used to make multiple copies. After the vessel form was completed, press mold techniques were utilized to decorate the large thrown forms. Some of the low-relief sculptures that are represented on the vessels came from casts of actual fossils; others were sculpted by studying photographs of real fossils. Each vessel represents a particular geologic period in time.
Sedimentary rock strata, such as limestone, siltstone, shale, and sandstone, are the predominate materials in which fossils are naturally preserved. For this reason, the surface decoration and glazes used on the vessels in the “Strata in Clay" series were carefully selected to resemble the appearance of these sedimentary rocks that typically encase fossil remnants.

There are three types of clay that ceramists typically work with when making sculptures or functional ware. Earthenware, or terra-cotta, is the lowest firing clay and is usually used for hand-sculpting. Earthenware is usually reddish-brown in color after it has been fired. Stoneware clay is a mid-range fired clay that is very durable and can be used for functional or sculptural artwork. Stoneware usually fires to become a dense, off- white or grayish clay. Porcelain is a very fine-particle clay body that is pure white when fired and can be heated to the highest temperature of the three clay types.

Clay is an artistic medium and a geological object: how do you reconcile these aspects?
Formed by the weathering and erosion of rock strata, clay seemed to be a perfect material to work with to create this series. The earth constantly recycles and rebuilds surface layers. As sand, silt, and clay weather away from older deposits, and new layers of sedimentary material form, occasionally an organism gets buried between the layers. Clay and the unique fossils found in the sedimentary strata of the earth are the focus for the Strata in Clay series.
What is your typical workflow for ‘Strata in Clay’?
When working with clay for the Strata series, I began by researching the fossil forms that I
The forms of the vases in the “Strata in Clay” series are reminiscent of ancient Greek vases and amphora. The vases are tall (2-4 feet in height) and thrown in multiple sections. The sections are stacked on top of each other to complete the vase to its full height. After the vase is thrown, I use the molds to make multiple copies of the fossils and apply them to the surface of the vase. Handles are often added to the form to create interesting negative space to the vessel. I try to make connections whenever designing and decorating these vases. The handles often take on the attributes of the fossils that are on the vase. The stains and glazes used to color the surface of the clay are selected to look similar to the rocks that the fossils were found in. The process of making one of the vases can take several months to research, create the molds and throw the vase, then decorate and glaze it.

In the medium of glass art, William Morris has been an artist that helped to inspire some of my artwork. His Artifact series led me to have a vision of what I wanted to create in my Strata series. Morris’s Standing Stone series motivated me to create very large forms.
Ceramic artist Maria Martinez inspired me in my work with clay. Martinez’s forms and special firing technique inspired me when I was creating the form and firing the vase that represents the Pennsylvanian period. During the Pennsylvanian period (one half of the Carboniferous age) there were large quantities of coal deposited in the strata of the earth. The form of the vase is a traditional wedding vase, the surface of which has been polished with a sooth rock in the style that Martinez typically produced. The vase was heated up to 1500 degrees in a Raku kiln and then placed in a metal barrel filled with sawdust and newspaper. The hot vessel tries to burn the organic material, but because the barrel is sealed, no oxygen can get in. The normally white clay turns jet black in the process, which is referred to as carbonizing. The black vase is meant to look like the coal that is so often found in the Pennsylvanian deposits.

For the Strata in Clay series, my focus was to communicate the concept of geologic time periods. The series of vessels helps to communicate this concept by creating a vessel for each of the twelve time periods. As an educator and a visual artist, I wanted to show people what life forms were most prevalent in each of the twelve geologic periods. I researched the fossil record and consulted with other geologists to determine what fossils to place on some of the vases. The artwork in the series helps to illustrate the complex evolution path that life on earth has taken during the last 540 million years.

I have been working as a professional artist for 29 years. In my studio I worked with clay, stained glass and blown glass materials to create artworks for sale and for commissions. Since I became an arts educator, it has been more difficult to find time to work on my own artwork. It has been rewarding to finally complete the geologic vases and have them on exhibit in a gallery where people can learn about geology, the evolution of life on earth, as well as enjoy the aesthetics of each piece in the series.
What was the turning point in your professional career?
The largest turning point in my career was when I decided to switch from working as a
Is there a client base for ‘geological ceramics’?
Over 300 students from local schools as well as several hundred community citizens came to view the exhibit during the seven weeks that the show was at the McConnell Arts Center (MAC) in Worthington, Ohio. None of the vases were purchased, but my hope is that the entire series of geologic vessels will be purchased by an institution and used for educational purposes someday.
|Alan Spencer, Silurian (from the Strata in Clay series).|
I have not had any of my artworks exhibited in a scientific institution. The Strata in Clay series is the first collection of mine that has had a geologic theme. I have been researching, sketching designs, making the molds, and throwing the forms since 2004. None of the pieces from the collection were available for purchase until January of 2014 when the exhibit went on display at the MAC in Worthington, Ohio.
|Alan Spencer, Cretaceous (from the Strata in Clay series).|
I feel that it is important for artist to know about geology because the rocks, the earth, fossils and crystals, can all be such a strong source of inspiration for many forms of artwork. So many of the raw materials used in any artwork come from the strata of the earth. It is imperative to be aware of these materials and how to use them properly to create successful artworks. I believe that the more knowledge an artist has at his/her discretion regarding subjects like geology, the more variety that artist will have to be inspired in different directions.
