A Little History
The earliest crude leathers were made by first immersing the raw hides and skins in a fermenting solution of organic matter in which bacteria grew and attacked the hides or skins, resulting in a loosening of the hair or wool and some dissolving out of skin protein. The hair or wool was then scraped off with primitive blunt stone or wooden scrapers and fat or meat still adhering to the flesh side was removed in a similar manner. Tanning, the conversion of pelt into leather, was done by dusting the rawstock with ground up bark other organic matter and placing them in shallow pits or vats of tanning solution. Further additions of ground bark, were made from time to time until the tanning solution had penetrated right through the skin structure, taking up to two years for very thick hides. The leather was then hung up for several days in open sheds. The dressing of the leather involved paring or shaving it to a level thickness, colouring, treatment with oils and greases, drying and final treatment of the grain surface with waxes, proteins such as blood and egg albumins, and shellac to produce attractive surface finishes.
The majority of the leather was tanned with oak bark but soft clothing, gloving and footwear leathers were tanned with alum, oil, and combinations of these two materials.
With the discovery and introduction of basic chemicals like lime and sulphuric acid, tanners gradually abandoned their traditional methods and leather production slowly became a chemically-based series of processes.
The growth of industrialization in the 18th and 19th centuries created a demand for many new kinds of leathers, especially belting leathers to drive the machines being introduced into industry, special leathers for use in looms in the textile industry, leathers for use as diaphragms and washers, leathers for use in transport and for furniture upholstery.
At the end of the nineteenth century, the invention of the motor car, modern roads, new ranges of coal tar dyestuffs, the demand for softer, lightweight footwear with a fashionable appearance, and a general rise in the standard of living created a demand for soft, supple, colorful leather. The use of the salts of the metal chromium was adopted and chrome tanning became the tannage for modern footwear and fashion leathers. It produces soft, supple, beautiful and fine leathers, reflecting the way we live.
About Walnut Studiolo
Necessity is the mother of invention!
Portlander Geoffrey Franklin started Walnut Studiolo in October 2009 when he found himself needing durable, beautiful leather accessories for his bicycles. As an avid rider and active north westerner, he was inspired to create products he had not been able to find on the market. His background in design and degree in architecture from the University of Oregon, along with his passion for traditional mediums, have driven his product line and produced unique and functional products that are highly sought after.
His first product was a leather u-lock holster. He followed that with handlebar wraps, and next up was a portage strap for carrying his bike. He then began working one-on-one with customers to design custom products. One such item was a polo mallet holder. They sold a few here and there for several months until inspiration struck! Geoff realized the mallet holder could be used to strap a 6 pack to his bike! He re-listed the item on Etsy as a “Six-pack Frame Cinch.” Oregonians do love their beer, so word spread quickly. After favorable press from several websites and blogs, the company’s growth was rapid.
The company has now expanded from just bicycle accessories to producing interior design products, several beer and wine products, and travel-sized games, just to name a few. They also still accept custom work orders.
Geoff and his wife Valerie grew the business into a full-time occupation, quitting their other jobs in 2011. The company hired its first additional employee in 2013.
Geoff says the company’s mission is, “To design durable, unique, and functional (awesome) products that we want to use ourselves and that are:
- Hand-tooled in Portland, OR
- Made out of durable natural materials like leather and wood
- Sourced with an emphasis on local-made and USA-made suppliers
- Produced using environmentally responsible methods and materials.”
Walnut Studiolo has received much praise and many local awards, as well as a nomination for the 2015 Martha Stewart American Made Crafts Awards.
