Using his apparatus for an early demonstration of [[powder metallurgy]], Spring found that high pressures could fuse metal powders into solid metallic objects. Further, he found that the high pressures generated by his apparatus could combine mixtures of powdered copper and powdered zinc into layers of brass, this transformation occurring at the interface between the two types of powders. These experiments showed that [[Alloy|metal alloys]] could be formed under sufficiently high pressures.<ref name="Distillations" />

In further experimentation with his high pressure equipment, Spring showed that sufficiently high pressure converted [[peat]] into a substance much like soft coal or [[lignite]]. He likewise showed that calcium carbonate (chalk) could be made into a material resembling marble under the action of pressure, and he showed that certain clays combined with organic matter under high pressure produced a substance like schist found in the local Belgian region. Another example of Spring's demonstrations was showing that compressing barium sulfate and sodium carbonate over extended periods of time produces barium carbonate and sodium sulfate.<ref name="Distillations" /><ref name="JChemEd1961" /><ref name="Takacs" />

Twenty-five of Spring's 150 scientific publications were on the subject of chemical transformations induced by high pressure.<ref name="Takacs" />
