Using the Crucible Cradle will help alleviate many of the problems associated with the proper handling of the crucible. You can now eliminate the need for the use of crucible tongs. Many students find the use of tongs awkward and end up dropping the crucible. The Cradle will also eliminate the need to touch the crucible after it has been heated. Oils from the finger tips can add weight to your final results, and throw off your findings.
