Though it looks dark, it retains the clarity and low-yellowing characteristics of raw walnut oil, this stand-oil–style medium offers exceptional leveling, richer gloss, and extended working time—perfect for glazing, fine detail, and impasto in both oil painting and encaustic techniques. Recommended for use with shades or darker colors for a rich viscosity unlike any other medium.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eKey Features\u003c\/p\u003e\u003cbr\u003e\u003cp\u003ePolymerized for Gloss \u0026amp; Flow: Heat-induced partial curing increases viscosity and produces a self-levelling, high-sheen film.\u003c\/p\u003e\u003cp\u003eLow Yellowing Index: Maintains the pale golden tone of walnut oil with minimal darkening over decades.\u003c\/p\u003e\u003cp\u003eExtended Open Time: Slower drying (24-48 hr to touch dry) allows for smooth wet-into-wet blending and precise layering.\u003c\/p\u003e\u003cp\u003eSuperior Film Strength: The lightly polymerized oil forms a more elastic, crack-resistant film than raw walnut oil.\u003c\/p\u003e\u003cp\u003eArchival Stability: Natural antioxidants retained during low-temperature pressing guard against oxidation and rancidity.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eUsage \u0026amp; Care\u003c\/p\u003e\u003cp\u003eBlending: Warm slightly or work on a heated slab for peak fluidity; disperse with a palette knife or glass muller until fully integrated.\u003c\/p\u003e\u003cp\u003eStorage: Seal tightly; store in a cool, dark environment to preserve viscosity and prevent skin formation.\u003c\/p\u003e\u003cp\u003eCleanup: Remove excess with odorless mineral spirits, then wash tools with mild soap and water.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eElevate your painting and encaustic practice with the luxurious gloss, flow, and archival resilience of Morrow Archival Burnt-Plate Walnut Oil.\u003c\/p\u003e","brand":"Morrow Archival","offers":[{"title":"4oz","offer_id":47875331129566,"sku":null,"price":34.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0739\/2821\/2702\/files\/04618bb1-a628-4bb1-b3f5-1f98c45f0aa2-copy.jpg?v=1769984587","url":"https:\/\/morrowarchival.com\/products\/burnt-plate-walnut-oil-medium-425137984","provider":"Morrow Archival","version":"1.0","type":"link"}
