Sirchie Shake-N-Cast Impression Kit, Set of 8

The Sirchie Shake-N-Cast Impression Kit features a self-contained, pre-measured water capsule and dental stone casting material packaged in a single, heavy-duty plastic pouch. This incredibly simple-to-use kit eliminates all the mess and guess-work inherent with many other casting mediums.

The mixture is always the right consistency. It contains 2 lb (32 oz) of dental stone and 14 fluid oz of liquefier, factory-sealed in a tough plastic pouch. One kit is sufficient for casting a full-sized, adult shoe print. Simply apply pressure to break the water capsule, shake and knead the container for up to two minutes, cut off a corner of the pouch and pour it into the impression. When working in loose, dry soil or sand, they recommend preparing the impression with dust and dirt hardener.
