OPINIONS AS TO VALUE OF WOOD TURPENTINE. 45 



pentine made by the old process. The only objection that we have heard is with 



;:ird to the odor. 



Spirittine Chemical Co., Wilmington, N. C.: The solvent power is the same. It 

 dries as well and there is no more liability for varnishes thinned with it to check than 

 those made with gum spirits. There is a difference in odor, a slight difference in 

 jolor, but neither enough to injure its usefulness. We have as customers for this 

 product many of the leading paint and varnish manufacturers and they have been buy- 

 ing to their complete satisfaction for many years. 



OPINIONS OF PAINT AND VARNiSH MAKERS. 



Murphy Varnish Co., Newark, N. J.: Our tests of this material have shown that it is 

 not so well adapted to varnish-making purposes as pure spirits of turpentine. It is 

 objectionable on account of the odor and also because less of it is required in the manu- 

 facture of gum varnishes than the pure spirits of turpentine. As turpentine is the 

 [cheapest ingredient it is obvious that the cost of such varnishes is increased by its use. 



The Glidden Varnish Co., Cleveland, Ohio: We are experimenting with wood tur- 

 pentine continually, but up to the present time have been unable to find any product 

 that was entirely satisfactory in odor. The proper deodorization of wood turpentine 

 would no doubt make this product as valuable as pure gum spirits. In all of our 

 experiments with a high-grade wood turpentine we find that the working properties 

 of same are equal to those of gum spirits, but wood turpentine gives varnish or paint 

 a very pungent odor which is very disagreeable to the user. 



Harrison Bros. & Co. (Inc.), Philadelphia, Pa.: Properly distilled wood turpentine free 

 from pyroligneous impurities has equal or better solvent properties than gum spirits. 

 It dries as well, but possibly a little slower. Varnish made with it is in no way inferior 

 to one made with gum spirits so far as working and physical properties are concerned. 

 The principal objections raised by painters and consumers are the odor and irritating 

 action of the vapors upon the eyes, while some painters claim that it also produces 

 nausea. 



Chicago Wood Finishing Co., Chicago, III.: The solvent power of wood turpentine is 

 equivalent in every way to gum spirits. In drying it is not so much slower than there 

 would be any great disadvantage. Mixed with varnishes we find that it is equivalent 

 to gum spirits when mixed in any quantity of almost any kind of varnish in which a 

 gum spirit would be used. It does not differ, as far as we have seen, in working 

 qualities from gum spirits. The principal objection is its extremely pungent odor 

 which, to most people, is very disagreeable, and in some cases causes violent head- 

 aches. Because of this odor we prefer the gum spirits. 



Longman & Martinez, New York City: The best quality of wood turpentine evapor- 

 ates much slower than gum turpentine, and were it not for the odor of wood turpentine 

 it would probably be as well suited for use, to as large an extent, in paints as is gum 

 turpentine. Neither is of any value whatever in respect to furnishing durability to 

 paint. The odor of even a good quality of wood turpentine is not so often an objection- 

 able feature. 



Atlantic Drier & Varnish Co., Philadelphia, Pa.: The solvent power is equal. It 

 dries as well and does not differ in manipulation from ordinary turpentine. It does 

 not make an inferior varnish, and paint or varnishes made with it do not differ per- 

 ceptibly in covering power from ordinary turpentine. Painters, consumers, and 

 workmen all agree in objecting seriously to the strong odor and to its bad effects on 

 the eyes. It is very much more offensive in every way than ordinary turpentine. 

 We have found such serious objections because of the odor that we have abandoned 

 the use of the material entirely. 



Boston Varnish Co., Boston, Mass.: We have not gone into the flexibility or life of 

 wood turpentine, but in our opinion from what we have used it is equally as good as
