About Hess Pumice
Hess Pumice Products, located in southeastern Idaho near the community of Malad City, is a mining operation and processing company specializing in the extraction and refining of high-quality pumice.
Hess Pumice, favored by nature with a vast reserve of pumice—as high a quality as any available on earth—is dedicated to the highest standards of refinement, accuracy of grading and quality control. This, coupled with our commitment to efficient, responsive “On Spec - On Time” customer service, makes Hess a world-class pumice supplier, able to meet your pumice product needs at any specification.
In continual operation since 1958, Hess Pumice operates production facilities equipped with the most current refining technology and machinery.
Hess Pumice has a stable source of supply, an exclusive focus on producing precisely controlled industrial grades of pumice, and the logistical expertise to ship pumice anywhere on the planet. This focus has made Hess Pumice the world’s leading supplier of highly refined pumice products.
Hess Pumice Products was founded on good fortune and nurtured by hard work and optimism. It all began when founder Marion Hess’ construction business went bust. He took what equipment he had left, and with the encouragement of a nearby farmer, dug up an area where the farmer couldn’t get anything to grow. Marion ripped up a quantity of the white volcanic pumice rock and shipped it to a Salt Lake City company who bought it—and much more—to use in lightweight concrete block.
Hess Pumice sales took off when Marion’s son Marvin, a newly-minted engineering graduate of the University of Utah, discovered that the television industry was buying fine-grade pumice for use in polishing and finishing television screens. His father’s pumice deposit certainly fit that need. Exceptionally, it turns out. It was quickly evident that the pumice coming out of Malad City, Idaho was the best in the world, as it was chosen by manufacturers worldwide, even by those who had a local pumice supply nearby.
In 1971 Marvin designed a small pilot plant inside a converted diesel shop and he and his father began the process of developing and refining a fine-ground pumice product. They tirelessly refined and tweaked their process and gradation capabilities to the extent that Hess Pumice became the market choice for the television glass industry. And with this growing capability in high-grade pumice, Hess entered the global market in the late 80s.
Hess Pumice quickly grew to dominate the world market for industrial abrasives, even in Japan, which had its own pumice producer, becoming the sole supplier to the screen glass division of NEC.
A large production facility was constructed in 1986, with a second built and placed into operation in 1996. Each plant is equipped with the latest tech and machinery for the production and packaging of some 300 pumice grades.
Hess Pumice continues to thrive by holding tightly to the principles that made them a world leader: produce a high-quality pumice product, meet customer specifications, and do it consistently and on time.
Three factors point to a exciting and sustainable future for Hess Pumice:
Our Wright Creek Area mine (located 22 miles northwest of Malad City) has a confirmed yield of in millions of tons of available pumice.
The company is family owned and managed, with the next generation already on the job and executing day-to-day operations.
We continue to invest in innovative processing methods and capacity while actively seeking new markets for our exceptional pure white pumice.
For example, we developed seven new microfine pumice grades (NCS 3, 5, 8, 10, 12, 15 and 20) for the fillers and extenders market, with additional applications in the paint, rubber and plastics industry.
Our pumice is a key component to the development of a highly-engineered replacement for the fracking sand critical to the oil and gas well fracturing process.
And we are leading the way in the renaissance of pumice as a natural pozzolan to super-charge modern concrete strength and durability, having commissioned extensive pumice pozzolan research studies by Dr. Paul Tikalsky and the University of Utah to establish the significant performance enhancements of adding pumice pozzolan to a concrete mix design. Additional studies on pumice pozzolan performance in concrete have been conducted by University of Texas-Austin, Washington University, Clemson University and others (download the research).
Inpired by the incredible versatity of pumice, we continue to explore applications for pumice in diverse industrial arenas.
