Hi. Welcome to Expert Village. My name is Jorge Benlloch. I was a teacher in Spain, and I'm a teacher here. I'm originally from Barcelona, Spain. Sorry for my accent. I try my best here in English. And today we are going to introduce you to different kinds of clays. Mainly, I like to work with clay because we have the opportunity to use the plasticity of the material. There's many different kinds of sculpting, or making figurines. One, it's chiseling, and taking the material off. Another one is putting the material on. Another one is just modeling, and squeezing, and making the things and the forms happen. Now, we have here, two different water based clays that are going to be used to make all modeling we want, and they can be fired in the kiln. This is the red clay, very popular and it becomes ceramic, very hard, after firing at really high, very high temperatures. We are going to do today something different, but it will be self-containing and self-drying figurines, that we don't need structure. All clay, mainly the water based clay, they shrink after drying. They shrink between five percent to fifteen percent. Then, when you have to plan that when you are trying to projecting of a sculpture. It's going to be smaller, that's number one. And number two, if you put a self-standing structure to help the sculpture standing up in the moment that you are building them, you have to cut and take the structure out when the clay starts being a little bit harder than you can work on that. Anyway, this is the two main water based clays.
