What do you cover the containers with? The plastic covers that comes with pyrex doesn't seems to be anything special.

  That’s silicone - and (after a quick fact check) essentially inert biologically

    If its really inert, why isn't whole container made of it?

      Some containers are. I have bought reusable silicone sandwich bags that you can freeze or put in the oven(up to 450 degrees F) if you leave the bag unsealed.

        I also have entire silicone containers (work well for avocados etc)
