The Dos and Don’ts of Ceramics

and Glazes

Page 2: Dos and donts of clay power point

Do cover clay with a plastic bag to keep it from drying out. This applies to works in progress and moist clay. A damp paper towel should be added to the bag if the project will not be touched for two days or more.

Page 3: Dos and donts of clay power point

Do keep your area clean while you are working and after you are finished. Gather any clay scraps off the floor and clean with water and a sponge. Clay dust can be harmful if you are exposed to it for long periods of time, so you must use a damp sponge to clean areas.

Don’t create appendages sticking out from the main part of the piece that are longer than your thumb or thicker than your thumb. If the piece is longer you can wrap it around the piece. If it is thicker you must hollow it out.

Do use the score and slip method to attach clay to clay. This must be done in the moist and/or leather hard stages.

Page 6: Dos and donts of clay power point

Do wedge clay to remove air bubbles, achieve uniform consistency, and to line up the particles of clay. Clay straight from the bags is rep-wedged but recycled clay will need to be wedged.

Do hollow out sculptural forms and put needle holes from the bottom so air can escape. Trapped air can cause clay to explode. Hollowed out forms dry quicker. Any piece NOT hollowed out will not be fired.

Page 8: Dos and donts of clay power point

Do handle your project with two hands at all times. In other words BE CAREFUL it’s your hard work. Never lift pots by the rim. Don’t HANDLE ANOTHER PERSONS WORK EVEN IF IT LOOKS COOL! You may break it!

Do put your name on the bottom of each piece or you will not receive a grade!

DO NOT POKE HOLES IN A BAG OF CLAY!

Page 12: Dos and donts of clay power point

Or Mrs. Spike will get you and your little dog too!

Page 13: Dos and donts of clay power point

Do ask BEFORE using any Glazes or Underglazes.

Page 14: Dos and donts of clay power point

Do glaze a piece only after it has been fired once (bisqueware). You cannot put glaze on a Greenware piece.

Page 15: Dos and donts of clay power point

Do use Underglazes on greenware.

Page 16: Dos and donts of clay power point

Do wash the clay dust from your piece by running it under water. Wash the bisque piece before you glaze it.

Page 17: Dos and donts of clay power point

Do use only the brushes that are especially for glazes. MAKE sure they are washed dried and put away after each use! ALL GLAZE BRUSHES MUST BE WASHED OUT VERY THOUGHTLY!

Page 18: Dos and donts of clay power point

Do use only “Food Safe” glazes on pieces you plan to eat from, at least on the inside of the piece. Clear glaze is always food safe. Most glazes are marked, if you are unsure ASK!

Page 19: Dos and donts of clay power point

Do use the pour method when glazing a piece with a narrow neck or large inside. ONLY USE CLEAR GLAZE! You only have to do it once.

Page 20: Dos and donts of clay power point

Do brush on glaze in three thin coats. You only need two coats of clear glaze.Do fill the brush with a good amount of glaze and brush it on very quickly. It will dry very fast.

Page 21: Dos and donts of clay power point

DO NOT GLAZE THE BOTTOM OF YOUR PIECE AND LEAVE A ¼ INCH UNGLAZED RIM AROUND THE BOTTOM.

Page 22: Dos and donts of clay power point

Do use more than one colour of glaze on a piece but DO NOT MIX GLAZES. Some colours run more than others.

Page 23: Dos and donts of clay power point

Do shake the jar and then after opening it stir it with the handle of the glaze brush. Wipe the handle clean with your fingers back into the jar.

Page 24: Dos and donts of clay power point

Do wipe the rim of the jar and the inside of the lid to prevent it from sticking later when finished using.

Page 25: Dos and donts of clay power point

Do place finished glaze piece in proper area to be fired.
