Thesis on Gypsum

Abstract

The subject of this thesis is to try to prove that dead burnt gypsum will set if it has a nucleui to set around and for this nucleui to be furnished with a given % of either gypsum or plaster of Paris. To confirm the theory that the presence of a nucleui of a stable form has an essential influence and this can be accomplished by adding either gypsum or plaster paris to furnish the nuclei for the formation of new crystals.
