The Preparation of Soap
This Unilever Laboratory Experiment describes the preparation of soap from a mixture of cooking oil and dripping. The leaflet was first published in 1964 and so lacks modern safety guidance. The procedure is authentic; it is designed to produce a convincing sample of soap. This means that it could be the basis of an advanced investigation but is not suited to a quicker demonstration.
