Saggar box trays, also referred to as crucibles or sintering vessels, are a type of specialised kiln or furnace furniture made from high-temperature refractory materials.
Commonly made from cordierite, corundum or alumina–mullite, saggars and crucibles offer excellent thermal performance and chemical stability and come in a variety of shapes and sizes making them suitable in a wide range of applications requiring heatwork.
They are suitable for laboratory metal and non-metal sample analysis and material melting, and can also be used to protect fired wares from direct flame, kiln debris, kiln gasses and smoke.
