{"product_id":"yasutomo-japanese-bokuju-liquid-sumi-ink","title":"Japanese Bokuju Liquid Sumi Ink","description":"\u003cp\u003eVegetable oil soot ground to ultra-fine particles creates ink that flows smoothly without grit or separation. Yasutomo's pre-mixed formula eliminates the traditional grinding ritual, delivering consistent black intensity whether you're practicing kanji or building atmospheric washes in sumi-e landscapes. A small amount of shellac provides water resistance once dry, allowing you to layer subsequent washes without disturbing previous strokes, essential for traditional bamboo techniques where overlapping leaves must maintain their edges.\u003c\/p\u003e\n\u003cp\u003eWide-mouth bottles accommodate direct brush dipping, keeping your workspace clean and ink access immediate during practice sessions. The cap doubles as a brush rest, a thoughtful detail that matters when you're working through repetitive strokes and need to pause without searching for a place to set your brush. Pour-spout versions offer controlled dispensing into smaller wells or mixing dishes. Permanent formulation means finished work won't fade or wash away, while non-toxic composition makes it suitable for classroom environments and extended studio sessions.\u003c\/p\u003e\n\u003cp\u003eAvailable in traditional black and sepia tones. The sepia provides warmer tonality for studies where stark black feels too harsh, or for creating depth variation within a single composition.\u003c\/p\u003e","brand":"Yasutomo","offers":[{"title":"vermilion red \/ 2 oz. \/ wide mouth bottle","offer_id":47977635512549,"sku":"13472","price":6.21,"currency_code":"USD","in_stock":true},{"title":"black \/ 2 oz. \/ wide mouth bottle","offer_id":47977635545317,"sku":"59029","price":5.95,"currency_code":"USD","in_stock":true},{"title":"black \/ 12 oz. \/ wide mouth bottle","offer_id":47977635578085,"sku":"68169","price":15.42,"currency_code":"USD","in_stock":true},{"title":"black \/ 6 oz. \/ bottle with pour spout","offer_id":47977635610853,"sku":"81005","price":10.24,"currency_code":"USD","in_stock":true},{"title":"black \/ 2 oz. \/ bottle with pour spout","offer_id":48001798963429,"sku":"81113","price":6.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s59029.jpg?v=1770299803","url":"https:\/\/www.texasart.com\/products\/yasutomo-japanese-bokuju-liquid-sumi-ink","provider":"Texas Art Supply","version":"1.0","type":"link"}
