Getting Started with a Subscription

The First Box Includes:

  • 1 x 8+ lb bag of screening material, with over 1.5 lbs of rocks and minerals

  • A reusable sifter and scoop

  • Identification booklets or cards to guide you through identifying new rocks and minerals

    Each Month You Will Receive a New 8+ lb Bag of Screening Material and Identification Booklet/Card

You can sift the mix just about anywhere! But be mindful of your surroundings.

Choose a location that is stable and will not be damaged by water, dirt, or the specimens.

Plumbing + sand don’t mix!

The sifters are 10 inches wide, so you’ll want a container that is at least 15 inches long and 11 inches wide. Your container should be large enough to comfortably fit the sifter, with some room to move.

A typical 16-quart plastic storage bin works perfectly!

Since you can’t sift the mix in your bathtub or sink, you’ll need a container that is at least 6 inches deep.
