Premium 10oz Borosilicate Glass Jars - Complete Instruction & Care Guide OUR STORY: ENGINEERED FROM FEEDBACK We started like many others, using standard borosilicate glass. But our customers spoke, and we listened. They wanted jars that felt more substantial, more durable for daily use. That feedback became our blueprint. The Upgrades We Made: Glass Thickness is noticeably increased for a heavier, more premium feel. Reinforced Bottom is enhanced through optimized manufacturing for superior durability. Extended Annealing is optimized for excellent thermal shock resistance. Result: A jar with a noticeable heft and resilience you can feel the moment you hold it. PREMIUM MATERIALS FOR FOOD STORAGE Our jars are made with borosilicate glass, polypropylene lids, and silicone gasket seals. These materials are selected for food storage applications and daily kitchen use. Glass Material: Premium Borosilicate Glass (heavy-gauge) Lid Material: Food-Grade Polypropylene (PP) Seal: Removable Silicone Gasket QUICK START GUIDE For Freezing: Fill to approximately 10oz (300ml) to allow adequate headspace. Loosen the lid (a quarter-turn, do not tighten fully). Keep jars separated during freezing (not touching). For Heating: Thaw at room temperature or in refrigerator first. Remove the lid entirely before heating. Microwave and oven safe at recommended temperatures. For Storage: Stack neatly at any time. Clear glass shows contents at a glance. Colorful lids make identification easy. PRODUCT SPECIFICATIONS Capacity: 10oz (approximately 300mL) for standard use; up to 350mL at maximum fill Glass Material: Premium Borosilicate Glass (heavy-gauge) Mouth Diameter: 3 inches (76mm) Temperature Range: Suitable for freezer-to-oven use Lid Material: Food-Grade Polypropylene (PP) Seal: Removable Silicone Gasket Dishwasher Safe: Yes (top rack, remove lid and gasket) FREEZING GUIDELINES Liquids expand when frozen. For freezing, fill to approximately 10oz (300ml) to allow for expansion. Loosen lid slightly (do not fully tighten) to allow pressure relief during freezing. TRANSPARENCY NOTES About the Jar Base: Our manufacturing process creates a thicker, more robust base through an extended annealing process. Due to the cooling characteristics of this premium manufacturing technique, some jars may have a completely flat bottom, while others may have a barely noticeable curve. Both are completely normal and indicate our reinforced construction. These natural variations do not affect strength, safety, or performance. About the Silicone Gasket: We continuously improve seal design to enhance durability and user satisfaction. The current gasket is safe, tested, and fully functional. CARE INSTRUCTIONS Glass Jar: Dishwasher safe (top rack). Remove lid and gasket first. Lids & Gaskets: Hand-wash recommended for longevity. Drying: Air dry completely. Ensure the jar rim is dry before reassembling.
