Best Clay For Raku Pottery

The best clay for raku pottery is a low-fire stoneware clay. Low-fire clays are more resistant to thermal shock, meaning that they can withstand larger fluctuations in temperature without breaking. This is important for raku firing, since the pottery is removed from the kiln while still hot, and then the pottery is exposed to sudden temperature changes. Low-fire stoneware clays also have lower shrinkage rates, which minimizes the likelihood of cracking during the firing and cooling process.

The best clay for raku pottery should also be a type of clay that is easy to work with. Raku pottery often involves intricate designs, so it is important to use a clay that is malleable and easy to shape. Additionally, the clay should have a smooth texture, as this will make it easier to apply glazes and other decorations.

Finally, the best clay for raku pottery should also be non-toxic, as some clays can leach toxins into the kiln fumes. Non-toxic clays are generally less expensive, so they can be more cost effective for larger projects.

Raku Pottery Clay: What You Need to Know for Optimal Results

Raku pottery clay is a type of ceramic clay that is used for hand-building or wheel-throwing pottery. It is a type of earthenware clay that is fired at a very low temperature and is known for its vibrant colors and unique finish. It is a popular choice for both professional and amateur potters alike.

Here are some tips and information on how to best use raku pottery clay for optimal results:

  1. When purchasing raku pottery clay, be sure to check the expiration date. Raku pottery clay is usually sold in blocks and can last up to two years if stored in a cool, dry place.
  2. Raku pottery clay is best used when damp and not wet. If the clay is too wet, it will be difficult to work with and can cause cracking during the firing process.
  3. Be sure to use the correct temperature and firing time when firing raku pottery clay. The proper firing temperature will vary depending on the type of clay being used, so be sure to check the manufacturer’s instructions.
  4. After firing, the piece should be cooled slowly in order to prevent cracking. This can be done by letting the piece cool in the kiln, or transferring it to a cool area such as a bucket of water or a large metal container.
  5. When glazing raku pottery clay, be sure to use a glaze that is specifically made for raku firing. Using a glaze that is not designed for raku can cause the piece to be damaged during the firing process.
  6. Finally, be sure to handle the finished piece with care. Raku pottery is fragile and can easily chip or break if dropped.
