AUREUS™ Bright Bronze Clay (50)

Offered in lump (wet) form, this clay results in a beautiful, bright bronze when fired. Economical, easy to form, fire and finish. Made in the USA. Kiln Fire: 2 Stage - Carbon Required. Shrinkage: 10-11% Firing Aureus Bright Bronze Clay requires a two phase firing. The first Phase completely burns out the binder, which helps the work sinter properly in the second phase. Many kilns fire hotter or cooler than their digital read-outs state. It is a good idea to test your kiln for temperature accuracy. This can be done with a hand-held digital pyrometer. Phase 1 Firing Full ramp to 650°F/ 343° and hold for 30 minutes -Option 1 Arrange greenware on a mesh firing rack. Additional pieces can be stacked using more mesh firing racks separated with kiln posts. Raise the mesh firing rack(s) off the kiln floor with a few more kiln posts for air circulation. -Option 2 The greenware can be placed on top of 1” of activated carbon in a steel firing container. Do not add activated carbon on top of the greenware for phase 1 firing. Laying flat can create little indents because bronze gets soft while sintering. Best to lay flat pieces vertical in the carbon. Note | A slower phase 1 firing is needed for any piece that has areas that are 3mm (12 cards) thick or thicker. Ramp 300°F/ 149°C hour to 600°F/ 315°C and hold for 15 minutes. Phase 2 Firing Full ramp to 1400°F/ 760°C and hold for 2 hours Once the greenware has cooled enough to handle after the first firing phase, gently transfer the work to a kiln vessel, such as a steel firing container that has at least 1” of activated carbon spread on the bottom. Arrange the pieces with at least ½” of space between them. Cover all pieces with at least 1” of activated carbon. Additional work can be added in layers as long as there is 1” of activated carbon above and below each piece. Fire with a slotted lid or lid ajar. Do not cover firing container completely.
