Hi there. It's been a long time since I've worked with clay. Do you always need to fire it?

    Hey Tim! The clay you are referring to is pottery clay. The types of clay that were introduced at the beginning of the learning flow do not need firing in a kiln. Some dry by simply being exposed to air (WED water-based clay; air-dry clay), others can be baked in a regular oven at about 275 degrees Fahrenheit (Polymer clay), and the others (castilene/Cx5 and all types of oil-based clays) need to be molded in a flexible molding material - such as silicone or latex - to produce a permanent copy of the original clay sculpture in resin or gypsum. Except for polymer clay and air-dry clay (to a certain extent), none of these materials are suited to yield a permanent sculpture and they will always require mold-making. I suggest you look through the videos of "Sculpting Mediums" to see each of them in action and get more detailed info on how to handle each material: https://cgcookie.com/course/sculpting-basics/ And if you have further questions down the road, please don't hesitate to ask! :) ~Lisa
