FAQ

Can Saint-Gobain Performance Ceramics & Refractories’ saggers be employed in highly automated processes?

Yes. Saint-Gobain Performance Ceramics & Refractories’ experienced engineers are on hand to recommend the most ideal product and design option for a highly automated production line, taking into account factors such as the mechanical strength of the sagger (for robot handling) or advanced thermal shock resistance (for loading or unloading).

Can Saint-Gobain Performance Ceramics & Refractories’ saggers be stacked?

Yes. A customized sagger design allows them to be stacked in a kiln, increasing volume output.
