Cool overnight - Allow extraction liquid to cool completely (12-15 hours) 10. *Collect lanolin* - Skim the solidified lanolin that rises to the surface 11. *Filter* - Strain through fine mesh to remove debris PURIFICATION: 12. *Reheat gently* - Warm lanolin to melt and separate from water 13. *Cool again* - Allow to solidify and separate 14. *Repeat filtering* - Strain multiple times for cleaner product EXPECTED RESULTS: *Yield:* 250-300 milliliters of crude lanolin per fine wool fleece *Appearance:* Olive green, sticky, waxy consistency *Time:* Full weekend process (active work + cooling time) *Smell:* Strong sheep odor that fades with purification USES FOR YOUR LANOLIN: *Fabric waterproofing* - Apply to wool, cotton, or linen *Leather conditioning* - Restore flexibility to boots, belts, gear *Skin protection* - Natural moisturizer for hands and face *Tool preservation* - Prevent rust on metal implements *Wood treatment* - Protect wooden handles and outdoor equipment SAFETY NOTES: Process produces strong odors - ensure good ventilation Handle hot water and lanolin carefully Raw lanolin may contain impurities - test on small fabric area first Store finished lanolin in cool, dark place MODERN ALTERNATIVES: If you can't access sheep fleece, you can purchase refined lanolin from: Pharmacies (often in skincare section) Natural product stores Online suppliers Craft/spinning shops However, extracting your own gives you the complete medieval experience and understanding of this ancient process! --- This recipe preserves the authentic medieval method while adapting for modern safety and equipment.
