What Advantage Of This Product
What advantages does this product have?
- Non-porous tempered construction in this black opal glass cup blocks liquid absorption and odor retention—glossy surface remains hygienic through 1000+ commercial dishwasher cycles without cloudiness.
- Square geometry enables stable vertical stacking to save 40% storage space, while opal dinnerware handles 120℃ thermal shock for direct freezer-to-microwave transitions during peak service hours.
- Dense 191g weight provides tip-resistant stability that reduces breakage costs—black opal glassware maintains color saturation under UV exposure and heavy use compared to fading ceramic alternatives.
What risks can this product avoid?
- Seamless surface of opal tableware eliminates bacterial harboring in glaze cracks common with ceramics—this black opal glass cup prevents cross-contamination in institutional food service and healthcare settings.
- BPA-free and cadmium-free formula removes chemical leaching during microwave heating—heat resistant construction meets strict food-grade standards for pediatric and elder care facilities.
- Tempered opal glass withstands rapid temperature shifts without fracturing—square design avoids thermal shock breakage that creates sharp shards, protecting staff during rushed service in chain restaurants.
Why 80% Clients Prefe Us
CORELLE BRAND (OEM FROM US)
1. Material Purity and Formula Stability
Jointion utilizes pharmaceutical-grade silica achieving 99.9% purity with precisely controlled fluoride content maintained between 2.8-3.2% to create optimal light diffusion while preserving structural integrity. Our proprietary formulation incorporates:
- 0.05% cerium oxide for enhanced UV resistance preventing yellowing over extended exposure periods
- 0.1% zirconia for substantially enhanced toughness and crack propagation resistance
- 0.01% cobalt ensuring consistent whiteness across production batches
We control all details right at the initial stage, securing quality from the very source. We consistently uphold the philosophy that quality is built into production, not just verified through testing — which is why we’ve earned the recognition of Corelle.
