I am thinking about using Plastercraft to make molds of my 8th grade
student's hands, and I have a few questions about timing and process.
We meet for 45 minute periods; if we use hot or warm water will this allow
enough time for the plaster to set?
Also, should students use some sort of a release before applying the
plaster. I imagine that their skin may dry out a lot from the contact with
plaster, but has anyone run into students having more severe skin reactions
to the materials?
