Raku firing is a little bit different than other types of firing since oftentimes it has effects that are a little different than what others clay bodies would create with this. But, we’ll highlight what the best options for this are, and why they matter.
There are many different clays that you can use with your raku firing, but there are a few rules that you’ll need to keep in mind before you begin with this, and they are as follows:
· Don’t use earthenware if you’re looking to create crackle effects
· The closer it gets to vitrifying, the less of an effect the carbon has on reduction, so don’t use clays that get close to it
· Keep clay that has a lot of iron away from this, since it does resist the carbonization of the body itself

I personally enjoy working with clay every day and I would hate to see anybody be scared to work with clay. Over my years of pottery, I found clay to be a wonderful material. Children universally for thousands of years have safely enjoyed making artifacts with the clay in their villages. Hence, if clay is treated with respect and we use common sense, we can get all the fun and benefits of clay without risking our health. A lot of top-notch potters like to take risks in the design and content of their artwork, but when working with their materials and methods, they make enough effort to avoid any risk to their health and the health of their clients. All human actions involve some level of risk or danger. In that respect, yes, pottery can be dangerous. It carries a certain amount of risk.
Pottery clay is different from the inelastic soil and fine sand because of its ability. When the clay is wet with the proper amount of water, to form a solid figure and to retain its shape when molded. This quality is said to be the clay’s plasticity. When heated in high temperatures, clay partially melts, resulting in the tight, hard rock-like substance known as a ceramic material.
Clay minerals such as kaolin, smectite, and palygorskite-sepiolite are part of the world’s most important and useful industrial minerals yet its care is not taken it might be hazardous to your health. The smectite component of clay has been proven by scientist that is it toxic especially if sniffed. That is why it is crucial for you to wear a face mask when you are working with clay. In addition, all materials-related health hazards take years of exposure to become a serious problem. You should take the risks seriously, and know they are long-term.
