Frequently Asked Questions
Are mason jars with clamp or hinged lids truly airtight for liquids?
Clamp and hinged lids with a good silicone or rubber gasket can be airtight for most fridge-stored liquids and dry goods. However, for active fermentation or long unrefrigerated storage, metal canning lids with a tested silicone seal are generally more reliable.
Can I put these glass jars in the dishwasher and use them for hot liquids?
Most glass bodies are dishwasher-safe, but check the manufacturer notes on lids: foam-lined or certain plastic lids are better hand-washed to protect seals. Avoid sudden temperature changes (pouring boiling liquid into a cold jar) to reduce risk of cracking.
Do replacement lids fit different brands of mason jars?
Standard wide-mouth lids and many replacement packs (like FORJARS) are designed to fit common wide-mouth mason jars, but always check compatibility notes. Clamp-style and hinged jars use integrated tops and gaskets that are specific to the jar shape.
