Clay wedging Stone

Gather unto you some supplies:

• Plaster of Paris powder
• Mixing Bowl
• Measuring Cups
• Spatula
• Cookie Sheet that you never want to use again for anything else

Time of Work: 30 minutes  

Time until complete: 5 days to completely dry

When you're creating with traditional clay, the most important step is to remove any air from the clay. Air bubbles trapped in clay can explode during the firing process, destroying your creation. Removing air from clay is a process called wedging, and this is how you can create your own wedging stone.  

1. Follow the instructions to mix Plaster of Paris on the box. There will be a ratio of powder to water.

2. Measure carefully and combine in the mixing bowl.

3. Mix powder and water thoroughly.

4. Pour mixture into cookie sheet.

5. Set cookie sheet with mixture in it on a low traffic, warm, dry place to set. The mixture will technically set in just a couple hours, but I let mine set for a couple days to ensure its hard. 

Now that you've got your wedging stone, here's a tutorial on how to wedge clay.
