Dear Colleagues-
We would like to experiment with a substrate of wax, sand, sawdust, and petroleum jelly in our dinosaur dig, but don't know the correct proportions of the ingredients for creating the mixture. Do any of you have a recipe you'd be willing to share? We'd also appreciate any tips on maintaining the substrate as well as tools for visitors to use in their excavations.
Thanks for your help!
Lisa
