high borosilicate thick glass food storage container 400ML

High borosilicate glass is an excellent choice for food storage containers, offering significant advantages over regular (soda-lime) glass and plastic. Here’s a breakdown of why it’s highly regarded, especially when “thick”

• Borosilicate glass has a very low coefficient of thermal expansion due to its boron trioxide content (typically 13-15%). This means it resists extreme temperature changes (thermal shock) without cracking or shattering.
• You can take it from the freezer directly to the oven (up to around 450-500°F or 250-260°C) or microwave without worrying about breakage. This versatility is a huge convenience for meal prep and reheating.
• Thicker glass provides an additional layer of insulation and robustness, further minimizing the risk of thermal shock damage
