Stages of Clay 1. Greenware - clay is still wet, flexible, and moldable 2. Leatherhard Greenware - Clay is dried out and ready to fire (very FRAGILE!) 3. Bisqueware - Clay has been fired one time 4. Glazeware - Bisqued clay that has been glazed and refired - glossy surface
Preparing Clay Wedging pushing air bubbles out of clay so that it doesn’t blow up!
Four Clay Handbuilding Techniques 1. Pinch Pots- using a pinching technique with the index finger and thumb to form a pot 2. Coil - rolling the clay out with your hands, which creates a rope like piece of clay 3. Slab - rolling out or using your hands to create a flat ‘sheet’ of clay 4. Sculptural - molding clay into shapes using your hands
Clay getting dry? Reconstitute - to add water back to dried out clay to make the clay workable again You can also use slip to add moisture back to the clay What is slip? ? ?
Attaching Clay together. . . You must always SCORE AND SLIP! Score - making hatch marks into two pieces of clay to be joined together Slip - a mixture of clay and water that is applied to your score marks - it is the ‘glue’ for clay Combining the edges - this is where you ‘hide’ the seams created when joining two parts together. You can use the modeling tool, your finger, or putting a coil over the seam and smooth it over
Types of Sculpting techniques 1. Additive - process where you add sections of clay to your overall form 2. Subtractive - this is where you carve away sections of clay from a solid section of clay
