January 1960



Boyd and England of the Geophysical Laboratory at the Carnegie Institution of Washington DC build out the “belt” apparatus into the first piston cylinder device and use the equipment to facilitate the first laboratory synthesis of diamond.

Experience with the instrumentation accumulates.   Patera and Holloway of Pennsylvania State University innovate the equipment, making it easy and inexpensive to operate. The QUICKpress, as it becomes known, is originally designed to provide temperature between 25°C and 1800°C and pressure from 0.5 GPa to 2.5 GPa.  The equipment synthesizes a range of technologically-important materials and advances understanding of the Earth’s near-surface and lower crust, as well as extra-terrestrial lithospheres and atmospheres.

Depths of the Earth Company is founded by Dr. John Holloway in 1989 with the express purpose of designing, building, and selling QUICKpress non-endloaded piston-cylinder apparatus and providing the supplies needed for their operation.

Technology advances and innovations are thoughtfully incorporated into the QUICKpress apparatus.  In 1993 Dr. Tracy Paul joins Depths of the Earth Company as its first full-time R&D scientist.

The QUICKpress piston-cylinder advances understanding of the physical and chemical properties of the Earth’s interior by providing salient information to Earthquake studies, heat, fluid, and energy transport investigations and crustal evolution simulations.  The equipment finds innovative uses in biological studies of viruses and bacteria, as well as in materials synthesis of superhard nano composites, superconducting wires, ductile ceramics, and giant magnetoresistent metals.    The pressure and temperature range of operation for the QUICKpress is expanded —making the QUICKpress even more versatile and viable to an even greater number of research topics—by designing interchangeable pressure plate systems that utilize piston size to control applied force, first to the lower pressure stability range of 0.2 GPa, and later to a high pressure value of 4.0 GPa.

Dr. Holloway retires from academics and business in 2008. As a Professor Emeritus, his scientific pursuits continue to weave through and influence the high-pressure high-temperature experimental community. The company’s daily operation and future vision remains under the guidance of Dr. Paul.

The company returns to its foundation with the sale and installation of a QUICKpress piston cylinder apparatus to the Carnegie Institute in Washington DC.
