Title: Ceramics 1


1
Ceramics 1
  • Week 9

2
Patting/paddling
  • Hitting seam gently with a wooden tool
  • Reinforces joins to
  • Strengthen the joined area!
  • Realigns clay particles in one direction
  • Creates textures

3
5 Reasons Why Clay Becomes Bone Dry at Different
Rates
  • 1. Humidity clay dries faster in drier locations
    like Arizona than in Wisconsin

4
2.    Thickness
  • Thin walls dry faster than thick walls

5
3. Surface Area
  • The more exposed surface area the faster the
    surface will dry
  • Projections and appendages dry faster than the
    main pot

6
4. Air Movement
  • The side of the project that faces a breeze will
    dry first

7
5. Overall Size of the Form
  • Large pots dry slower than small ones

8
Force Drying
  • Placing a wet piece in the sun, under heat lamps,
    using a hairdryer, or heating vent to dry the
    piece quickly.

9
1st Reason to Avoid Force Drying
  • 1.  Pieces drying unevenly will appear dry but
    firing the piece will cause it to explode.

10
2nd Reason to Avoid Force Drying
  • When clay dries quickly it causes stress cracks
    and pieces can fall apart

11
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.

12
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

13
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

14
Symbols
  • Codes, patterns, and designs that represent
    reality using a general or simplified
    image

15
Creative Problem Solving Skill
  • Doodle

Begin by making a mark on your paper (or on your
pot) and work from the mark. It's like jumper
cables for your brainit gets your creative
juices pumping.

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.
