Clay Sculpture Techniques Using a Propane Torch

Fire small clay pieces with a butane torch.

Small clay sculpture pieces such as those used in jewelry do not need to be fired in a kiln, but can instead be fired using a propane torch. This avoids the need for a kiln drying facility, but also keeps the piece from breaking.

Types of Clay

Only certain types of clay such as PMC+, PMC3 or art clay silver work pieces can be fired using the propane torch. Pieces containing CZs and lab-grown gemstones can also be fired in this manner, providing extreme care is used. This firing method is not recommended for large hollow clay forms, as the firing time process will increase to more than a few hours.

Process

Extreme care needs to be used when utilizing a propane torch to fire clay sculpture pieces. The torch must be used evenly across the entire piece to avoid over-drying the clay in one area and breaking the design. It's easiest to use the torch drying method while the clay piece is spinning on a potter's wheel. Use the butane torch to dry the piece for 1 1/2 to 5 minutes depending on the size. Pick the piece up with metal tongs and dip in water to cool.

Safety

Practice safety measures when using a butane torch on clay. It's important to use safety goggles and gloves. Turn on the propane torch slowly so the gas opens up slowly and doesn't ignite a large flame. Place the flame of the butane torch at a 45-degree angle about 2 inches from the piece and move the torch around the entire piece constantly.
