The Cisily set is built around high-borosilicate glass, a material known for its low coefficient of thermal expansion. This allows the jars to move between different temperature zones, such as from a cool pantry to a warm countertop, without structural failure. The jars feature a 4-ounce capacity and are lead-free, ensuring a chemically inert environment for sensitive ingredients like ground cloves or cinnamon.
The lids are CNC-machined from bamboo and feature a 2.2mm thick silicone gasket. This thicker gasket is designed to provide better resistance to oxygen transmission compared to standard models, helping to keep spices flavorful. Because bamboo is a natural material, it is most reliable when hand-wiped and dried immediately to prevent the wood from swelling or retaining moisture.
Specifications indicate that while the borosilicate glass is highly resistant to heat, it is designed to break into larger shards if dropped, which can be easier to manage during cleanup than the fine granules of tempered glass. The square shape ensures the jars sit securely in drawer inserts without rolling during opening and closing.
For a smaller collection that uses similar high-durability borosilicate, the 12-piece glass spice jar set with bamboo lids is a practical alternative.
