Patting/paddling • Hitting seam gently with a wooden tool • Reinforces joins to Strengthen the joined area! • Realigns clay particles in one direction • Creates textures
5 Reasons Why Clay Becomes Bone Dry at Different Rates • 1.Humidity clay dries faster in drier locations like Arizona than in Wisconsin
2.Thickness • Thin walls dry faster than thick walls
3. Surface Area • The more exposed surface area the faster the surface will dry • Projections and appendages dry faster than the main pot
4. Air Movement The side of the project that faces a breeze will dry first
5. Overall Size of the Form • Large pots dry slower than small ones
Force Drying • Placing a wet piece in the sun, under heat lamps, using a hairdryer, or heating vent to dry the piece quickly.
1st Reason to Avoid Force Drying • 1.Pieces drying unevenly will appear dry but firing the piece will cause it to explode.
2nd Reason to Avoid Force Drying • When clay dries quickly it causes stress cracks and pieces can fall apart
3rd Reason to Avoid Force Drying • When surface area dries too quickly it shrinks more quickly than the clay beneath causing the piece to warp.
Air Dry Rack • Drying rack that has shelves made so that air can reach all surfaces of the clay as it dries. Pots dry from the top down so turn pots upside-down on rack
Re-softening Leather Hard Clay For clay that is slightly too hard but can be dented with gentle fingernail pressure • 1.Wrap project with a damp paper towel • 2.Place wrapped project into a plastic bag • 3.Wait overnight for moisture to be absorbed
Symbols • Codes, patterns, and designs that represent reality using a general or simplified image
Creative Problem Solving Skill Begin by making a mark on your paper (or on your pot) and work from the mark. It's like jumper cables for your brain…it gets your creative juices pumping. • Doodle
Paul Klee • “A line is a dot out for a stroll.”
Henri Matisse • “I am simply conscious of the forces I am using and I am driven on by an idea that I really only grasp as it grows with the picture.”
