Handbuilding: Tricks of the Trade 

Skill Level - Previous experience in handbuilding and/or throwing recommended but not required.

Background
While the potter’s wheel originated in the Middle East approximately 5000 years ago, many cultures through history have always preferred handbuilding techniques. Today, handbuilding encompasses a broad range of utilitarian and sculptural form in contemporary clay. In our technological society we are so easily seduced by tools and machinery, assuming that the product of our endeavors will be improved by our use of these devices. In ceramics, that is sometimes a mistake. The wheel is appropriate only for certain kinds of forms, while handbuilding offers unlimited possibilities. The wheel tends to impose symmetry, unless the potter purposefully introduces asymmetry. Handbuilt form tends toward asymmetry, unless the potter asserts the choice and has the skill to make the work symmetrical. And no matter how symmetrical a handbuilt form might appear, it is never as mechanically symmetrical as most wheel-thrown forms, and therefore tends to communicates an organic, human quality, representing the hands, the movements, and the personality of the maker.

Workshop Description - Our objective is to get you to handbuild with a sense of adventure and discovery. We will explore unusual ways of approaching pinch, coil, and slab construction in order to develop a particular mind set, an adventurous inclination to use handbuilt forms in new ways, opening up the possibility of original form inaccessible through more traditional approaches. Although our primary concerns are design and construction, we will bisque-fire as much work as possible so that it can be transported safely.
        We will have a number of slide shows to introduce a broad range of historical and contemporary handbuilt form and technique.  I encourage you to bring samples, slides, or photos of your work to share with the group.  

Materials Provided On-Site by Host

bulletBuff or white cone 6 or cone 10 stoneware clay containing fine sand or grog (or terracotta for a low-fire workshop) - have on hand 75 lbs. per participant and 150 lbs. for presenter.
bulletOne gallon white vinegar
bulletTwo gallons of slurry made in advance from the claybody.  With a cutoff wire, cut a 25-lb. block of clay into one-inch slices.  Dry the slices completely, slake down in water overnight.  The next morning, remove the extra water, mix to creamy, lump-free consistency with drill impeller mixer, add a cup of vinegar, and then add water until it reaches a consistency where the slurry will not flow when the container is tilted unless it is shaken.  This consistency is important to the way I do handbuilding.  
 

Facilities, Equipment, Tools, and Supplies Provided On-Site by Host
Please note: the quality and content of this workshop depends on having all of these supplies.  I will bring my own hand tools, and in some cases I may bring some of these supplies.  Before ordering or purchasing extensive amounts of supplies please check with me to see what I am planning to bring with me. 

bulletDigital projector with standard PC connector cord.
bulletAppropriately dark room with large screen or large white wall.
bulletLarge sturdy work tables for handbuilding.  Heavy plywood-covered tables are best, but sturdy 3'x6' folding tables will work, with no more than two participants per table.  
bullet24" (plus or minus an inch or so) stool for presenter to use.  This is important.
bulletSlab roller with appropriate canvas sheets for rolling slabs (presenter and participants will transfer slabs onto their own canvas sheets).
bulletHeavy-duty rolling pin with approximately 15" by 3" barrel and bearing-mounted handles (Google "Vic Firth Maple Rolling Pin").
bulletSeveral sturdy banding wheels - CSI "lazy-susan" turntables are okay, and cast-iron or aluminum ball-bearing banding wheels are better.
bulletTwo clear plastic storage bins with lids (approx. 12" by 24" by 12" deep, for me to use as damp boxes).
bulletEight 24" by 36" sheets of 10 oz. canvas duck.
bulletAt least Six 24" by 36" pieces of 1/2" or 3/4" plywood for handling and flipping slabs (more if possible - if you have 24" by 24" pieces, they will work, but 24" by 36" are preferable).
bulletWood dowels - (they generally come either 48" or 36") one length each of 1/4", 5/16", 3/8", 1/2", 5/8" and 3/4".  If there is a choice, get the cheaper, softer ones rather than the more-expensive oak dowels - they release from the clay more easily.  Cut each dowel in half and bring both halves.
bulletOne plastic spray-bottle for vinegar water.
bulletTwo propane canisters, as used on standard propane torches - available from any hardware store or home improvement center.   I will
bring a torch body.  It would be helpful if someone can bring an additional propane torch.  If you want to purchase one, get the Bernzomatic TS-4000 - don't consider any other unit.  This is the best torch for this application, with one-handed ignition and operation.  It's available from any Lowe's or Home Depot or online.
bulletA supply of plastic sheeting to cover slabs - dry-cleaner bags or similar clear plastic is preferable.
 

Supplies for Participants to Bring
Depending on the particular venue, clay may be covered by workshop cost, or may be available for purchase on-site.  Joining slurry and vinegar will be provided. The following is a lengthy list of supplies for a workshop, but these are the things you will need in order to continue doing this work on your own, and we will be able to make better use of the available time if you bring all of these supplies.  Some of these supplies may be available on-site, but only if specified by workshop venue.  

Note: The Kemper tools and CSI banding wheels are available at www.bigceramicstore.com. The Stanley Surform tools are available at www.amazon.com - enter "Stanley Surform" in the search box.

bulletFour square yards of 10 oz. canvas duck, cut into 24" by 36" pieces - "10-ounce" is a trade reference to the weight per yard, and that's how canvas is sold in art supply stores.  If you buy from an awning, sail, or house painting supply business they might not use the ounce per yard reference, in which case you just need to look for good heavy-duty canvas.  
bulletStandard clay tools (the packaged Kemper kit contains a wood rib, stainless-steel scraper-rib, wood knife, needle tool, cutoff wire, small sponge, and trimming tools)
bulletKemper S-10 flexible stainless steel serrated rib (no substitutes)
bulletKemper RB-4 or RB-6 wood rib.  This rounded wood rib and the serrated stainless rib are both very important in this workshop.  
bulletMetal fork
bulletX-Acto knife - pencil-thin model with 1" tapered blade - no substitutions. 
bulletScissors
bullet18" or 24" ruler
bulletSeveral pencils
bulletOld ballpoint pen - cheap model like a Bic - excellent tool for tracing template patterns on clay and for general incising tasks. 
bulletCompass (for drawing circles)
bulletWood rolling pin with bearing-mounted handles - not one-piece rolling pin - for the best ones, Google "Vic Firth Maple Rolling Pin," and get the one with the 12" or 15" barrel and bearing-mounted handles - they are listed as either 2.75" diameter or 3" diameter, but either will work fine. 
bulletWood dowels - one length each of 3/16", 1/4", 5/16", 3/8", 1/2", 5/8" and 3/4" - available from any hardware store or home improvement center - cut them all in half and bring both halves.
bulletStanley "Surform Shaver" (short curved blade) and Stanley "Surform Pocket Plane" (5" flat blade). Get both types - these are made to be woodworking tools, but are excellent for shaving clay - they are available from any hardware store or home improvement center or online from www.amazon.com - enter "Stanley Surform" in the amazon search box.    
bulletSmall, sturdy turntable or banding wheel. The 8" CSI turntable available from most ceramics suppliers for around $15 is fine for our needs, but any sort of good-quality turn table or banding wheel will work.  Light-duty plastic kitchen turntables will NOT work.
bulletSpray bottle for vinegar water
bulletSmall bucket for water.
bulletSmall snap-lid container for slurry.
bullet6 manila folders (for templates).
bulletA selection of bisque stamps and/or other textured objects or materials to impress texture into the clay
bullet12 dry-cleaner bags or large plastic trash bags to cover your work
bulletSmall towel or other sturdy rag
bulletApron (optional)
bulletIf you are driving, bring a large clear plastic storage bin with lid, approximately 12" by 24" by 12" deep, to serve as a personal damp box.  Transport your supplies in a separate box so that this plastic storage bin will be available for its intended use.
