- Are these jars safe for canning?
- Water-bath canning of high-acid foods is the usual use for jars like these. Pressure canning is not recommended, since the glass is not tempered like Ball or Kerr jars.
- Do the lids seal properly?
- They close and keep dry goods fresh, but owners of budget sets report weaker vacuum seals than name-brand lids. For long-term canning, buy separate quality lids.
- Can they go in the freezer?
- Yes, if you leave headspace for expansion. Fill no more than about three-quarters full for liquids.
- Are they dishwasher safe?
- The glass is, on a normal cycle. Hand-wash the lids to keep the coating and seal intact.
- How do they compare with Ball or Kerr jars?
- Same quart size and wide-mouth thread, but thinner soda-lime glass and less reliable lids. The trade-off is getting six jars at once.
- What fits in a 32 oz jar?
- About four cups of liquid. That is a quart of stock, a pound of dry pasta, or two servings of overnight oats.
