FAQ
Q1: What makes a high borosilicate glass jar better than a regular glass jar for food storage?
High borosilicate glass jars are made with a specialty glass that contains boron oxide, giving them exceptional thermal shock resistance and chemical stability compared with ordinary soda‑lime glass. This means they can safely handle rapid temperature changes — such as going from freezer to oven or microwave — without cracking, and the inert material won’t react with food or absorb odors. These properties make them ideal for preserving a wide range of food products, from dry goods and spices to acidic foods like sauces.
Q2: Are high borosilicate glass jars safe for everyday kitchen use, including heating and freezing?
Yes, high borosilicate glass jars are food‑safe and designed for everyday kitchen use. Their low thermal expansion coefficient allows them to withstand significant temperature differences without breaking, so they are suitable for freezer, refrigerator, microwave, dishwasher, and some oven applications when the lid is removed (always check lid material limits). The non‑porous surface also resists stains and odor buildup, simplifying cleaning and maintaining hygiene.
Q3: How should I care for and maintain my high borosilicate glass jar to ensure long‑lasting performance?
To maximize durability and performance, clean high borosilicate glass jars with warm water and mild detergent, and avoid drastic temperature shock (e.g., removing a frozen jar directly into very hot water). Although the glass itself is highly heat resistant, any bamboo, wood, or non‑glass lid components should be removed before heating. Most high borosilicate jars are dishwasher‑safe, but gentle hand washing of lids and seals helps preserve airtight performance.
