My first graders were ready to glaze their animal sculptures this past week.
Before unleashing them, I had a discussion about the differences in the clay during the firing process. They observed examples of clay in the 3 stages of greenware, bisqueware and glazeware.
We compared the color of the clay (gray to pinkish white to yellowish white), the finish (dull to shiny) and how the clay felt (smooth, rough, smooth) in the various forms.
Before handing them their sculptures, I dip the bottom into hot wax to prevent the glaze from getting on the bottom. It cools almost immediately so no worries! I use an old crockpot whose glass lid broke.
Wax resist solution can cost $11 a pint and up depending on the vendor (I would need several pints for 29 classes) but for about the same cost I can get enough canning wax (about 3 - 4 boxes, found in most grocery stores where canning supplies are sold) to do all my clay projects for the year - Can you hear the savings? Cha-Ching!
