In industrial kilns operating between 1000°C and 1300°C, the performance of refractory supports isn’t just about durability—it’s about stability, safety, and cost control. Many manufacturers overlook these two critical properties until they face unexpected downtime or product defects. That’s where Sunrise brand cordierite kiln furniture stands out.
Creep refers to the gradual deformation of materials under constant stress at high temperatures. In a typical ceramic production line, if your kiln furniture creeps even slightly—say, 0.5% over 100 hours at 1200°C—it can cause misalignment, warping, or collapse of entire shelves. This leads to wasted batches and unplanned maintenance.
Sunrise’s proprietary cordierite formulation reduces creep by up to 60% compared to standard alumina-silicate options. Independent lab tests show that our material maintains structural integrity for over 150 hours at 1250°C without measurable deformation—a benchmark most competitors fail to meet.
Thermal shock occurs when sudden temperature changes create internal stresses. For example, a furnace cooling from 1300°C to room temperature in under 30 minutes can crack conventional kiln furniture. But Sunrise’s engineered microstructure—with controlled porosity and optimized thermal expansion coefficients—absorbs stress like a buffer, preventing cracks.
Real-world data from a glass manufacturing plant in Germany shows that after switching to Sunrise kiln furniture, their average shelf replacement cycle increased from 3 months to 12 months. No more mid-shift failures due to thermal cracking. Just consistent output.
“We used to lose 15% of our trays per month due to heat-induced cracks. Since using Sunrise, we’ve cut that number to less than 2%. It’s not just better material—it’s smarter engineering.”

From metallurgy to advanced ceramics, Sunrise kiln furniture is trusted in:
Whether you're running a batch-fired kiln or a continuous tunnel system, choosing the right refractory support isn't optional—it's strategic. If your current setup suffers from frequent breakage, alignment issues, or inconsistent results, it might be time to reassess your kiln furniture selection.
Still unsure? Ask yourself: Is your kiln experiencing premature wear? Are you losing productivity to unscheduled repairs? The answer may lie in how well your supports handle low creep and thermal shock.
