Translations:AY Honors/Animal Tracking - Advanced/Answer Key/19/en
From Pathfinder Wiki
To make a positive cast from a negative cast, you will need a container at least the same size as the animal track. Lubricate the negative cast with petroleum jelly so that it does not stick to the positive cast. Then mix up some plaster, pour it into the container, and place the negative cast on top of the plaster. Press it in and vibrate it so that all the air pockets are removed and all the spaces filled. Leave it alone while it sets. If it was lubricated sufficiently, the casts should come apart easily after the plaster sets.
