46 WOOD TURPENTINE. 



regular turpentine. In our opinion a varnish reduced with it would produce a 

 product that would be absolutely impossible for any painter to use in any quantity 

 in a close room. The principal objection to it for medium and high-grade varnishes 

 is its odor. The above remarks apply only to the pure, properly made, and well- 

 refined article. 



C. A. Willey, New York City: From careful experiments in a practical way I am 

 fully convinced that it will do everything that an ordinary turpentine will do, but 

 the trouble is with its odor, of which the painters immediately complain so that we 

 were obliged to discontinue its use on this account. Recently there is much improve- 

 ment in the odor of some samples. 



Charles H. Howell & Co., Philadelphia, Pa.: From some little experience we have 

 come to the conclusion that barring the smell, the dark color of that which has simply 

 been distilled, it is a good product, answering all purposes of gum turpentine, with 

 only the objectionable odor against it. Our experience with the clear white article 

 which we think is produced by treating with caustic is that it is utterly worthless, 

 being very detrimental to paint, and especially to oil paint. Such treatment takes 

 the greater part of the oil out and leaves an article no better than benzine. It con- 

 tains a strong alkali which forms a soap of the oils in paints, and kills their durability. 



Standard Varnish Works, New York, N. Y.: For our requirements we find this 

 article to answer the same purposes as spirits of turpentine, the only noticeable differ- 

 ence being the odor, to which the trade seriously objects. 



Berry Bros. (Ltd.), Detroit, Mich.: We do not and never have considered distilled 

 turpentine as being equal in any respect to old process goods. 



Emil Caiman & Co., New York, N. Y.: We find that for many purposes it will 

 replace the gum article. Its solvent power appears to be about the same and when 

 properly manufactured it will dry as well as ordinary turpentine. We do not find 

 any material difference in working qualities. There is objection from buyers of 

 materials to the odor, which is stronger than that of gum turpentine. These remarks 

 apply only to properly manufactured wood turpentine. 



Boykin Manufacturing Co. (Inc.), Cheraw, S. C.: We have been marketing wood 

 turpentine to the paint, furniture, and buggy manufacturers with success. We rarely 

 have a kick on account of quality, and this class of trade claims that the wood turpen- 

 tine does their work as well as the old process turpentine does. 



The Institute of Industrial Research, Washington, D. C.: The solvent power of wood 

 turpentine is high and is probably not less than that of gum spirits of the same specific 

 gravity. When properly prepared and purified, it dries as well as gum spirits. From 

 this point of view it is therefore a good varnish material and is said to work free and 

 exhibit good covering power. The principal objections to wood turpentine are made 

 on account of its unpleasant odor and lack of uniformity. It contains, if improperly 

 purified, certain * * * products which are said to have a bad effect upon the 

 kidneys of workmen who have to handle it. These properties when present also make 

 it unfit for interior application. 



John Lucas & Co., Philadelphia, Pa.: Perhaps definite or practical information on 

 the subject of the commercial value of this product in comparison with the gum tur- 

 pentine is not of a very reliable character. Experiments made or experience gained 

 may not have been such as to fully determine the point. We have heard that varnish 

 made from a wood product would, when applied over a varnish made from gum spirits, 

 on account of its higher solvent nature, dissolve the surface of the previous coats and 

 render the rubbing down almost impossible. In drying we have not noticed any 

 particular difference. It has been our experience that a good grade of wood turpentine 

 is equal in every respect to the gum spirits. A varnish properly made with wood 

 turpentine of a satisfactory grade has just as good rubbing qualities as the gum-spirits 

 varnish. The principal objection is its odor.
