Domestic tanners come here to take short courses sponsored by the U.S. "This is the only public facility of its kind in the United States. "We have our own pilot plant tannery here at ERRC," Marmer says. He heads the ERRC's Hides, Lipids, and Wool Research Unit, a part of USDA's Agricultural Research Service. "Not only does our research benefit the hide-tanning industry, it also promotes the health of the environment," says William N. But scientists at the Eastern Regional Research Center (ERRC) in Wyndmoor, Pennsylvania, have come up with innovative ideas to increase the efficiency of processing those animal skins into leather, while ensuring better quality end products. The process that turns raw cowhide into supple leather is a complex one. Fortuitously, Roger Barlee’s youngest child shows interest.ARS industrial specialist Gary Dimaio (left) and biochemist David Bailey inspect a cowhide being packaged for preservation by irradiation. We also hope that the tradition of producing very fine book leathers will continue at Hewits through to future generations. We hope the insights above have helped you to appreciate the morocco that so elegantly binds ANTARCTICA and LABYRINTH SUBLIME. We have selected this specific book leather for LABYRINTH SUBLIME and for ANTARCTICA because it is simply the best available anywhere in the world today. No doubt, Chieftain Grade I is a very expensive leather to produce. We expect that you may have discerned that the production of this high-quality leather is more of a passion than a business. He then cuts our pieces making best use of the leather. He looks at each individual hide under multiple light conditions to spot any blemishes, which he marks with a pen. These six pieces of leather required for each volume are personally cut from the leather hides by Roger. Each presentation box uses two pieces of leather: the spine piece and the frontice piece. Each of our tomes uses two large pieces of leather on the covers plus the two additional pieces for the leather joints (inside the front and back covers joining the cover to the end-leaves). The final step is one that Roger Barlee personally undertakes, and that is the cutting of our pieces. This additional process serves to create a Ph buffer against possible the corrosive effects of air pollution to the leather over the decades to come. Toward the end of this retannage, aluminum salts are added so as to reduce acidity of the leather, and to enhance archival characteristics of the Chieftain leather. Acidity, temperature, concentration and type of tanning agents, rotation of the drum and agitation are all variables that determine the quality of the tannage. An increasing concentration of vegetable tanning agents (a combination of sumac, tara and myrobalan) are added to the liquor which is allowed to thoroughly penetrate the hides. The next step is to stabilize the rehydrated hides and transforming them into a durable, flexible leather. ![]() First the goat hides are soaked and washed thoroughly to remove the majority of the local (unknown) tannage and anything else that may yet be adhering to the hides. ![]() The processes that follow take place within these drums. Within these metal safety cages revolve huge wooden drums. ![]()
