Two 7-9 inch vessels Vessel 1 – Symmetrical Vessel 2 – Up to you! Csvessel
Student examples Wax and masking tape resist
Student examples Under glazed design
One vessel must contain the following. Lip
For this assignment you must complete at least three sketches for approval before making a template. This will count for 25 points of your final grade. It’s important to analyze how feasible your vessel container will be to make. For the second vessel, drawings only will be required, not a template.
Using the combination of geometric shapes to create your new vessel profile.
Template Before you start, you must make a template of the profile of your vessel. The vessel itself is not to exceed 9 inches. Sharp turns are difficult to accomplish, use gradual changes in profile!
Your vessel should mirror your template as you work.
Beginning Construction : Foot / Base The foot or the base of the vessel can be a slab or constructed from coils 2-4 inches diameter Roll your coil, watch the moisture level!
Score Scoring refers to roughing up the surface of your clay in preparation for attachment. You can use a fork, needle tool, toothed rib tool or fettling knife. You must score both surfaces to ensure that your coils don’t separate during handling, drying or firing.
Slip Slip is liquified clay about the consistency of mayonaise. Make sure your viscosity is a thick soupy mixture and not mostly water. Slip must be used on scored surfaces when attaching clay to create a tight bond. If slip is not used, your clay coils or additions may separate.
Attachment Attach your coils and seal all seams with downward pressure. Continue to attach all coils by scoring both surfaces, applying slip and seal seams with downward pressure.
Sealing No seams are to show on vessel 1, inside or out. This is done for strength of your vessel. For vessel 2, you may leave your coils exposed
Support your ware on the outside while you smooth coils on the inside. A modeling tool may work better than a rib tool. Hand on outside for support or you may distort your form.
Bench / Banding wheel Use a bench or banding wheel to rotate your vessel and refine the silhouette or profile of your vessel. Attach 2-3 layers of coils, check the form with template! These wheels turn so you don’t have to handle the ware to turn it. REMEMBER, 2 parts, carry with 2 hands!
Attach your coils, seal the seams, work on the form, check on your form for symmetry with your template.
Add more coils. Check the form. Make sure #1 is symmetrical.
Form Use rib tools and paddles to refine the form, don’t worry about small imperfections on the surface, focus on the symmetrical form. Use the rib at a 90 degree to scrape the surface, at a 45 to smooth the surface. Work on making the appearance of the coils disappear into the form. If you work too fast, it might slump or fall down, it you work too slow it might dry out to the point you can’t successfully add more coils.
Symmetrical? Check the outside wall profile Observe the top view
Template Use the template! It is a tool to help you make a symmetrical form while rotating your ware on the banding wheel.
Surface Build in layers of 2-3 coils at a time. Seal and smooth the additions with tools, refine the form with rib tools. Try the wooden, metal and rubber rib tools, you may like one over the other.
Placement of the coil How and where you place the coil dictates the form. Inside placement decreases the diameter, outside placement increases.
Surface Be careful in handling your ware. Always use two hands to carry or move your work. Grabbing on one side may crack the ware.
Sponging Only use as a last effort to smooth fingerprints on the surface. Don’t use a soaking wet sponge! NEVER ON MOIST CLAY--you will create sagging, that’s when your pot falls apart!
Vessel #1 Must have: Lip Neck Shoulder Body Foot
Surface Treatment You are allowed to under glaze and clear glaze or glaze the entire vessel.
Finished with construction? Let dry slow and make sure the inside is sealed
