lol.....the gamma lids look a lot like old commercial 5 gal paint lids. They used to have slots you had to cut, then remove the lid. A gasket was on there too. I'm not sure whether they still make them like that today. To buy a 5er at HD or Lowes, does not come with a gasket.
I go to a couple local restaurants and ask the cooks to save the empty 1 gal pickle jars, then, bring a six pack in exchange. The half gal kerr jars also work well. Actually, I have 5gal, 1 gal, 1/2 gal, quart and pint size glass depending on the yield. My jars are cloudy, I think I need to do the iso wash.
