Ted Neal's Buttressed Vase, stoneware, iron-bearing slips, fired in a wood kiln to cone 10, 2026.

Several years ago, I dreamed of a blueberry patch in my yard. This led to the construction of 40 feet (12.1 m) of raised beds to accommodate several varieties. Despite my best efforts, after a few years of valiant attempts to keep them alive, I realized it was not to be. Although that endeavor had not succeeded, it led to having lots of room for new flowers. I now enjoy all aspects of the process of growing flowers, from preparing the soil, seasonally planting and digging bulbs, and displaying the arrangements in our home. I find the cyclical nature and the feeling of the earth in my hands synonymous with more familiar ceramic processes. One of our favorites in the flower beds is gladiolus. The slender flower stems are beautiful, long lasting, and continue to bloom once cut. 

These vases are an amalgam of my interests in functionally displaying flowers while experimenting with themes of structure, volume, restriction, compression, and deformation. I enjoy how the flowers contrast the dark industrial forms and surfaces achieved through the wood-fired, reduction-cooling process. 

Throwing in Two Parts

Although a single piece is possible, the sharp transition between top and bottom is easier to precisely control when done in two parts. You can use between 2–3½ pounds (32–56 oz) of stoneware clay to throw the base, which might be best described as a parking cone with a slightly convex volume. After throwing, smooth the surface with a long rib (1). This step is important for clarity of the surface lines that will be added later. 

Next, add horizontal lines when the form is still on the wheel and the clay is freshly thrown. Use ribs with a corner or other small pieces of metal (2) to push into the spinning surface to create the appearance of raised bands around the form (3). Once all bands are made (4), push the form back out to its original shape from the inside with a throwing stick. This is critical as it gives the appearance that the raised lines were added above an otherwise flush surface. 

Throw the top of the form from a larger hump of clay while measuring to fit the base. I find the proportion of the top is most pleasing when it mirrors the circumference of the widest part of the base. Add horizontal bands in the same fashion as the base (5), and then cut the top off from the larger hump of clay. It’s a good idea to leave a little extra clay for a perfectly trimmed fit when attached later.

1 Smooth thrown surfaces in preparation for adding fine details later. 2 Tools for banding: Cut down ribs or use ones that have sharp corners.

3 Add horizontal bands while the clay is freshly thrown.4 Continue to refine the bands with sharp-cornered tools.

5 Throw the vase top off a larger hump of clay and measure it to fit the base. 6 Add division marks to the form using a circle divider and right-angle square.

Surface Alterations and Assembly

You can store parts wrapped on a porous surface, such as a plaster bat or drywall, until they reach a level of dryness that I refer to as “suede hard” (credit Kristen Kieffer for the term). When the clay is at this stage, you can carefully manipulate it enough to press into the clay and make marks, without cracking, yet it is firm enough to handle easily without unwanted deformation. 

Begin by marking six divisions (or as many as you prefer) using a circle divider and transferring corresponding marks up the side of the base (6). Then, press rigid metal tools into the surface on each side of the marks to create the appearance of raised vertical ridges perpendicular to lines made on the wheel (7, 8). These lines provide a visual structure that acts counter to the thrown volume to help create the illusion of constriction. You can exaggerate this further by gently pushing inward with your fingers at the intersection of all lines on the base and on the top edge of the form (9). 

Once leather hard, score both parts, making sure all ridges are aligned when you attach the two pieces (10). Smooth the joint (11).

7 Press rigid square edges into the surface of the clay for vertical lines. 8 Continue making impressions into the clay when it is suede hard.

9 Press the form further at the intersections to emphasize a tufted appearance. 10 Score and attach the sections making sure to align the vertical ridges.

11 Smooth and refine the attached top and bottom sections. 12 Create a custom buttress template for each vase from cardstock.

Finishing Details

Form the buttress material by rolling out ½–¾-inch (1.2–1.9-cm) coils and then flattening them with a brayer into a triangular shape. Since no two vase forms are perfectly identical, it is best to create a simple template out of cardstock custom made for each vase (12). When your coils are leather hard, use the template to cut out enough for each of your divisions (13). Score and attach them at the intersection of the top and bottom of the vase and align them with vertical ridges (14). You can use a Surform tool to soften the curve of the buttress slightly to blend the transition from the pot to the buttress (15). 

Finally, you can add finials on the upper and lower ends of the form (see 15). Of course, there are infinite variations of form, scale, proportion, and detail that can be used to create differences within the vase theme, so have fun experimenting with the possibilities!

13 Make buttresses by flattening thick coils into a triangular shape. 14 Score, attach, and align the buttresses with the vertical ridges on the vase.

15 Use a Surform to create a concave surface on each buttress.16 Bisque fire. Use blue painters’ tape as a linear resist when applying a liner glaze.

17 Continue to use the blue tape as a funnel to pour glaze out of the vase. 18 Apply a resist, then dip the vase in a thin slip made for wood firing.

Glazing

Preparatory to the wood firing, and after bisque firing, my vase forms have a simple interior liner glaze and a high-iron flashing slip on the exterior. Since my slip and glaze do not like to be layered, I keep them separate on the form. 

You can begin with a liner glaze, such as shino, which is kept just below the interior rim of the bisque-fired piece using painter’s tape (16). This technique terminates the glaze at a specific location while also providing a funnel to help pour the glaze out of the vase without spilling it in unwanted areas prior to applying slip (17). 

After the liner glaze sets, if you need to avoid other overlaps, wax over the glaze about 1 inch (2.5 cm) below the interior rim. This keeps slip off the liner glaze when you dip the exterior (18). 

The slips I use are designed for the wood-fire, reduction-
cooling process. The recipes are simply 100% laterite or 100% Cedar Heights Redart, mixed with water, and applied thinly over bisque.
