Photo: Sara Kempner.I believe that most potters and ceramic artists will agree, the holidays present a wonderful opportunity to create special, fun, and festive pieces that would not normally appear in our everyday repertoires. Ceramic ornaments have become very popular in recent years and many of us have tried our hand at our own unique creations. After several attempts, I have come up with a slab-built version with a bit more dimension. 

My own personal style of decorating involves textures, stamping, and slip dots. Each is finished with transparent, colored glazes and, sometimes, lusters. This ornament can be decorated in any way you wish to suit your unique artistic style. 

Forming the Body 

Begin by rolling out a ⅛-inch-thick slab using a dowel on each side of your clay for even thickness (1). When rolling such thin slabs, it is helpful to start with a thicker dowel size and reduce the thickness gradually. I normally start with ⅜  inch thickness and proceed to reduce the thickness in several stages. Tip: Remember to flip and turn your slab as you go, which will help to prevent unevenness and warping in your finished piece. Using ⅛-inch-thick slabs keeps the finished piece as light as possible so that it won’t weigh down a tree branch.

If you are more comfortable using a thicker slab, you will still be able to achieve excellent results using 3/16- or ¼-inch-thick slabs. It is important to smooth each side of your slab with a metal or rubber rib in order to smooth the clay particles. This will also remove any canvas texture from the slab. 

1 Roll out a clay slab using a set of ⅛-inch wood dowels.

Next, add decorative texture to the slab, if desired, using stamps, texture plates, fabric, lace, etc. The textures that I use come from my own designs. I create stamps and rollers of all sizes, from the same clay body that I use for my finished work, which are then bisque fired. I often create large texture plates from these smaller stamps. I begin with a slab that is rolled to at least ⅜ inch (and up to 7/16 inch) thick. I then impress the slab with a collection of smaller stamps to create patterns. These larger slabs are dried slowly between two sheets of drywall board to alleviate warping. I like the idea that all of the patterns and textures that I use come from my own imagination and fit together like a family. I also enjoy being able to make stamps specific to the project that I am working on, such as a mandala design for a round ornament and so on. 

Cut two circles for each ornament using a metal circle cutter or a paper template (2, 3). For this project, I have used a cutter measuring 7 cm in diameter. If you do not already have one, a good set of stainless-steel round cutters (typically used in the kitchen for baking) is a very good investment for handbuilders. 

2 Using pastry cutter, cut out two circles per ornament. 3 Remove the excess clay from around the cut circles.

Take each circle and form it into a curve by pressing it firmly yet gently over a sphere-shaped object covered with plastic wrap (4). Depending on the size of the circle, you may use such items as a tennis ball, golf ball, the end of a light bulb or whatever else you may have on hand. Allow the formed pieces to stiffen to medium-hard, leather hard. I place the pieces in a damp box overnight at this stage (see how to make and use a homemade damp box below). 

Once the two halves are firm enough to handle without distorting the shape, use a Surform around the rims to create flat edges that will perfectly fit together, then score the flat edges (5). 

Join the two halves together using slip or Magic Water (6) (see recipe below). My preference for handbuilding is Magic Water, which I find cleaner and easier to use than slip. If you are using Magic Water, use a paintbrush to apply it to the scored rim of each piece, using the brush to work it into a thin slip without over wetting. Join the two halves together and compress the joined edges using fingers and/or a pony roller (7), then smooth the seam with a rubber rib. 

4 Form each circle into a curve using any sphere-shaped object of appropriate size. 5 Surform the edges of each half to level the surface, then score the surfaces.

6 Join two prepared halves using slip or Magic Water. 7 Compress and smooth the joined edges using a pony roller.

Pierce a small pinhole to allow air to escape as the ornament dries and shrinks (8). Place the piece back into the damp box for at least a few hours or overnight to allow the moisture content to equalize throughout the piece. In the meantime, roll out a few small coils (approximately 1 cm in diameter) which will later be cut into short pieces and used to top the ornament and receive the wire hanger. Place the coils in the damp box along with the ornament. 

Adding Detail and Finishing 

You may wish to create a more whimsical look to your ornament by adding small details. I like to add a cone to the bottom and a small topper into which I insert the hanging wire. 

To create a cone, begin by rolling another ⅛-inch-thick small slab and smooth it with a rib. Place a piece of plastic wrap on top of the slab and use a small cutter (in this case 4.75 cm in diameter) to cut a circle (9). By using the plastic wrap in this way, you will achieve a smooth, rounded edge to your circle, giving the finished ornament a more polished look. 

8 Make a pinhole to allow air to escape as the piece dries and shrinks. 9 Cut a circle for the cone using plastic wrap between the clay and the cutter.

Cut a wedge out of the circle (approximately 135°) at a 45° angle (10). Join the two cut surfaces to create a cone shape (11) and smooth the join. Place the cone in the damp box along with the body of the ornament, allowing it to stiffen up a little, being careful not to let it over dry. You are aiming for a piece that will not show finger marks, but not be so stiff that it will crack while being attached to the ornament. 

Before attaching the cone to the body, place it loosely upon the ornament and trace around it to mark where it will be attached. Remove any texture from the area and score along the edge where the cone will connect. (12). 

Attach the cone to the bottom of the ornament using slip or Magic Water. Remember to make a pinhole for air to escape. 

10 From a circle, cut both ends of a 135° section at a 45° angle. 11 Join the two cut and angled edges to create a cone shape.

12 Remove the texture and score the area where the cone will be attached.

From the coil that you rolled earlier, cut a small piece (approximately 1 cm in length). Cut a notch into one end (13) and attach the notched end to the top of the ornament. Insert a high-temperature wire hanger (14). The ones that I like to use are purchased as pre-cut and shaped high-temperature ornament wires from Amazon. 

At this point, if you wish, you may add extra details and/or underglazes to suit your style. Once again, because I am adding moisture and joining pieces together that may have different moisture contents, I will place the piece into a damp box for a few hours or overnight. Then, allow the piece to dry freely on a wire rack. Bisque fire the pieces. 

13 Make a small notch in the top piece, which will be attached to the ornament and will secure nichrome wire for hanging. 14 Insert the nichrome wire hanger into the top notch. This will allow you to hang a string or hook to the notch.

Glazing and Firing 

My preferred method of glazing these ornaments is by dipping. I have fashioned an S-hook out of wire to assist in the process. Place the bisque-fired ornament onto the S-hook and, holding the ornament firmly by the wire, dip it into your glaze (15). I dip my pieces in Nan’s Clear (see recipe), tinted with various colorants. Because the ornament is hollow and filled with air, it will try to bob up when you dip it so be sure that you have a firm hold. Hang the ornament from any convenient bar or rail as it dries. 

15 Using a length of wire threaded through the nichrome hook, dip the ornament into glaze. 16 Hang ornaments on a bead bar supported by two kiln posts. This keeps the pieces from sticking to the shelf during firing.

To fire, hang several ornaments on a bead bar (which may be purchased from any pottery supply outlet), and then place the bar across two kiln posts so that they may hang freely in the kiln. I have made extra supports from a ⅜-inch slab, with a groove running through the center, upon which to rest the bead bar, ensuring that it stays in place throughout the firing (16).
