The logwood tree grows in Mexico, Central America, Dominican Republic, Venezuela, Brazil, the Guyannas, Madagascar, and India. Mixed with iron, logwood gives good blacks – a colour difficult to achieve with natural dyes. Logwood has good washfastness but moderate lightfastness – a bit of iron improves the lightfastness dramatically. Logwood chips will give a medium depth of shade at 10-15% WOF. \u003c\/p\u003e\n\u003cp class=\"p1\"\u003eLogwood has become increasingly rare. If using the extract, it is very easily dissolved and can be used directly in the dyebath at\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003e1-2\u003c\/span\u003e\u003cspan\u003e%\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eWOF for a medium shade.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s2\"\u003e\u003cb\u003eDyeing:\u003c\/b\u003e\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eFor chips - pour enough boiling water over the logwood chips to make a dyebath and soak overnight. Pour off this liquid and use for the first (and strongest) dyebath. Simmer fibres for about one hour, keeping temperature of dyebath between 77-83ºC (170-180ºF). If a darker colour is required leave fibres in dyebath overnight. The logwood chips can be soaked again and the liquid used for lighter shades. \u003c\/p\u003e\n\u003cp class=\"p1\"\u003eLogwood develops best in slightly hard water. Adding finely ground chalk (or a Tum’s tablet) brightens the logwood colour, especially if there is no lime in the local water. Cream of tartar can be added (at approximately 6% WOF) to push logwood to a purple-navy, adding osage or fustic gives grey-greens, cochineal gives purples, coffee bean browns are obtained by adding cutch, navy can be had with a dip in indigo, greys to blacks are made with the addition of iron.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eFind more information on this dye and others we carry\u003ca href=\"https:\/\/naturaldyes.ca\/instructions\" target=\"_blank\" rel=\"noopener\"\u003e here.\u003c\/a\u003e\u003c\/p\u003e","brand":"maiwa fabrics","offers":[{"title":"Default Title","offer_id":45383024738486,"sku":null,"price":79.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0582\/3211\/1286\/files\/20200411_TM_3601_89b1cc73-08aa-4b73-835e-72bdb6553af2.webp?v=1787686618","url":"https:\/\/nscadartsupply.ca\/fr\/products\/logwood-chips-225g-8oz","provider":"NSCAD Art Supply Store","version":"1.0","type":"link"}
