Understanding porcelain with Antoinette Badenhorst

If you understand the character of porcelain clay, you should be able to control the movement, the thickness, and the colors of porcelain art. It is worked and handled like clay, but when fired, it becomes glasslike. Porcelain art is known for its translucency, beauty, and strength. For centuries, it has been used as fine dinnerware in kitchens, but has proven to be strong and solid in outside constructions and even in space. That may be the reason why Antoinette Badenhorst refers to porcelain as the "Diva of clay".

This online porcelain class is designed to make a transition from stoneware or earthenware clay to porcelain. There are clear and specific differences in the approach between these clay mediums.

​Week 2 - Get to know porcelain clay
Learning to control porcelain starts with pinching. Pinching clay is a great starting point to understand porcelain and to learn how to control the drying stages of the clay.

During this week of the ceramic online class, Antoinette teaches beginner potters how to throw porcelain on the pottery wheel. She guides and challenges intermediate to advanced potters to push the limits on the wheel to throw very thin and translucent porcelain bowls and cylinders. Designing is an integral part of this week’s class and should prepare ceramic artists for getting back in their own pottery studio. 
​

• Prepare the clay and the environment for throwing clay on the pottery wheel.

• Building the walls of the bowl and steady the hand movements to control the shape. 
• Throwing V-shape and U-shape bowls on the wheel.
• Learn how the speed of the wheel and the speed of the hand movements influence the throwing process.

​Week 4 - Trimming porcelain
​Trimming with the right tools at the right drying stage may take potters to making transparent porcelain. If you have never trimmed porcelain, this is your chance to learn to do that successfully. You will learn how to trim smooth and even walls and will learn to prevent slumping and cracking in the rims.  
​

• Trimming basics for porcelain.

During this class, the whole course begins to fall into place and students will see why they should learn how to do things, but also why it is needed to do things in a specific way. This ceramic school teaches potters the how and why reasons.
​

What students say about the porcelain class.
​"I think the class has been very well thought out. The details included in the PDF downloads complete the class. It is just as though I have a textbook to refer back to. l like this class format because it gives me time to experiment, and I get direct, specific, personal answers. I cannot think of any way the class itself can be improved." - Nancy (Washington)
