MERGING TYPE ( GLAZE B Item v ) ] AND STAINS TYPE ,GLAZE El.1 Merging Type Glaze - ( which'facilitates the blending of various colours after application ) is a transparent pigment bound with a medium having good flowing properties, thinned with volatile solvent. B-2. STAINS B-2.1 Stains are soluble fast dyes or transparent, pigments, dissolved or suspended in an oil, water or spirit medium. The consistency shall be such as to ensure complete penetration. B-2.2 Stains are supplied either in liquid form ready for application or as powders to be dissolved in a suitable medium ( water, spirit or oil ) as indicated. If the medium is oil, driers and thinners may also be needed. B-2.3 Water stains are solutions of vegetable dyes in water. Solution of certain chemicals in water, although not .normally classed as water stains, are often used to, darken wood, such as floor-boards. Potassium permanganate is a well-known example. B-2.4 Spirit stains are solutions of spirit-soluble dyes in industrial methykted spirit. B-2.5 Oil stains may usually, to give a wider semi-pigments ground solvents. Sometimes, be solutions of oil-soluble dyes in linseed oil but range of colours, they consist of insoluble, transparent in linseed oil and thinned with turpentine or other wax is added to make the stain less penetrating. B-2.6 Oil stains are sometimes supplied mixed with varnish and sold as varnish stains, but where it is desired to enhance and not to conceal the appearance of the wood, better results can be obtained by staining and varnishing separately. 9 BUREAU tfeadqusflerss: OF INDIAN STANDARDS Manak Bhavan, 9 Bahadur Shah Zafar Marg, NEW DELHI 110002 Telegrams: Manaksanstha Telephones: 331 01 31, 331 13 75 ( Common to all Offices) Telephone regional Offices: 331 ,0'1 31 Central : Manak Bhavan, 9 Bahadur Shah Zafar Marg, 331 13 75 NEW DELHI 110002 I 36 24 99 : l/l 4 C.
