![]() the grain layer or dermal surface/papillary surface 3. Takes from 1 up to 5 days for thicker skins.ģ. To swell, the hide is soaked in a pickle of alkaline solution (pH up to 12), either of wood ashes, hydrated lime, or commercial lye. Swelling opens up and loosens the fibres, removes hairs and helps with oil penetration. ‘Liming’ opens up and swells the collagen fibres and breaks down non structural non fibrous proteins, mucins. Manually by scrapping, this step removes the flesh, that is fat and any meat adhering to the pelt.Ģ. For a detailed account of the structure of mammalian skins and the difference in structure between the animal types, see Kite & Thomson (2005).ġ. This tanning is method is not without some health hazards (Wescott, D. The fibres of the corium are course and loosely interwoven, resulting in stretchy leather, suitable for clothing. The grain layer takes 1/6 of the total thickness. The fibre structure of the skin is anisotropic, the skin is uneven in thickness. The thickness of deer skin ranges between 2 and 3 mm and measures from 0.9 to 1.3 m2. Terminology of the leather processing industry is used in this post (Covington 2009). Hide of a whitetailed deer ( Odocoileus virginianus) was tanned at the workshop. ![]() He is a great teacher who tans skins for a living and knows everything about producing a beautiful and long lasting skin. I learned a lot from Kfir and I highly recommend taking a workshop with him. My aim for the workshop was to gain familiarity with material properties of hides prepared by this method, and to get better at material identification and understanding conditions of historic artefacts made from hide. replication of technologies used before the invention of machinery to process natural materials, & he recently presented at the 2nd Annual Reconstructive and Experimental Archaeology Conference. Kfir specialises in the so-called ‘primitive technologies’, i.e. In May 2010 I took part in a brain tanning workshop with Kfir Mendel and his company ‘Two Wolves’. This post gives some insight into the process (1) and chemistry (2) of the wet scraping brain tanning and smoking method of deer hides. The hide is stretched and is completely dry after 5 hours of of being worked on the frame. Opening the hide between the oil dressing. ![]() Wringing the hide after rinsing in the ammonium solution. Nurse.Ĭondition of the hide after graining.
