WORKING WITH CLAY
Procedures for Working with Clay
Please use the open bags first and tightly close bags of unused clay with string or twist tie. Clay can be cut off into smaller chunks using a string pulled tight.
After forming images, students can apply underglaze to wet clay and to dry unfired clay. Pieces should be handled gently as they dry. Dry on boards or cloths and carry them this way. Dry clay is just dry mud, and it is very fragile.
Greenware
ALL GLAZES MUST BE APPLIED TO WET CLAY OR GREENWARE BEFORE THE PIECES ARE FIRED.
Pieces should then be transported to Mayeda Campus and left in teacher’s lunch room on the bookshelf near the copier with a note clearly stating the classroom and teacher, along with the name and phone number of the art parent that headed up the project.
Bisqueware
After the first firing, the ceramic pieces are referred to as bisqueware. After the pieces are fired once in the kiln, they can be glazed by parents. (You will be contacted when the pieces are ready.)
Three coats of clear glaze should be carefully applied, leaving the bottom of the piece and 1/8" up the sides unglazed. (When a project is fired, the glaze will melt. If there is glaze on the bottom of your piece, it will stick to the kiln.)
After glazing, the ceramic pieces can then be fired again.
RULE TO REMEMBER:
Greenware gets underglaze.
Bisqueware gets clear glaze.

Please allow at least 10 school days for your project to be completed. Firings will usually happen on Fridays.
