Is it safe to store clay in plastic containers?

By November 8, 2012 June 29th, 2018 clay basics, learning about clay

Last week, a customer wrote to ask us the best way to store hydrated Redmond Clay. Is it okay to store clay in plastic containers? It’s a question we hear often. Here’s the answer—along with a quick look at the reasons people ask.

Recycled Information

Most of what you’ve read about healing clays comes from a single source: A book called Our Earth, Our Cure by French naturopath Raymond Dextreit. Translated into English in 1974, the book is a gold mine of information about clay’s many uses—so good that each of the books (and, eventually, blog posts) about clay since then have borrowed heavily from Dextreit’s work.

Some books even copy entire pages verbatim, including the section when Dextreit talks about the best way to store clay. In this section (pictured below in two books, published 27 years apart) Dextreit suggests that hydrated clay shouldn’t be stored in plastic.

A fresh look at traditional answers

Much of what has been written about clay and plastic — even if the book was published just last decade, or the blog post was written just last year — is simply a restatement of what we knew in 1974. And let’s face it, plastic in 1974 was probably a bad idea! Some plastics today would be just as bad, which is why we need to be careful when mixing and storing our clay.

Not all plastics are created equal

Redmond Clay, dry or hydrated, can be stored safely in the right kind of plastic. Yep, we know it contradicts Dextreit’s 1970s advice, but plastics are much more stable than they were 38 years ago.

Redmond Clay approved plastic meets the following standards:

  • PET plastic, designated by the number 1: Used to store clay powder.
  • LDPE plastic, designated by the number 4: Used for our ready-to-use, pre-hydrated clay products. (Including Earthpaste.)
  • We use only “virgin” plastic. We love recycling, but for hydrated clay, we need to absolutely confident we know we’re getting just the right plastic. To be safe, we use only virgin, BPA-free plastic for our tubes. (Don’t worry, you can still recycle our tubes after you’re done!)

What about metal?

Dextreit’s original advice holds true: We don’t store clay in metal containers, and we don’t think you should, either.
