44 WOOD TURPENTINE. 



turpentines (also a light pine oil) behaved well under the brush and 

 no objectionable features in working other than the odor were 

 observed. After 18 months there is no apparent difference in the 

 paint thinned with the different turpentines. 



About five barrels of refined wood turpentine, which had been 

 obtained in the refining experiments, and of which approximately 75 

 per cent distilled below 170 C. were turned over to the painter of! 

 the department and used by him on all classes of paint and varnish 

 work from ordinary house painting to high-class furniture varnishing. 

 No inferiority in the finished work or in behavior in applying was 

 observed by the master painter. Only one workman made com- 

 plaint regarding this material, claiming that it made him ill. The 

 statement was not investigated. 



COMMERCIAL OPINIONS AS TO THE VALUE OF WOOD TURPENTINE. 1 



Before entering upon the research work on this subject the opinions 

 of those having occasion to use turpentines in large quantities was 

 asked as to the value of wood turpentine as compared with gum 

 spirits. 



OPINIONS OF WOOD TURPENTINE PRODUCERS. 



Cheraw Naval Stores Co. (Inc.}, Cheraw, S. C.: Our product is used largely by paint 

 men in the South, * * * who claim that it is better paint spirits than the old- 

 process turpentine. 



F. L. Huggins, Wilmington, N. C.: Wood turpentine dries better than ordinary 

 turpentine. * * * The only difference is in the odor. 



Morris Weslosky, Albany, Ga.: Its solvent power is as great, it dries quicker, and 

 varnish made from it is no more difficult to work than that made from ordinary tur- 

 pentine, but is more liable to check. Painters object to the odor and state that the 

 acid that seems to be left in it hurts their eyes. Consumers object only to the odor. 



Weed Distilling & Manufacturing Co., New York: We have heard no objection to 

 our products which are taken by the trade at the market rates. The oils for varnish 

 work are more readily sold every day. 



Chesterfield Naval Stores Co., Cheraw, S. C.: No objection has been raised to the 

 material. 



Tyler Lumber Co., New York: We find that the solvent property of wood turpentine 

 by the steam process is greater than that of gum turpentine. It will not dry as quickly 

 as gum, taking about two hours longer. It has been claimed that for carriage varnish, 

 etc., the varnish is not so flexible as when gum spirits are used. The only complaint 

 of any moment is made by painters and other consumers on account of the odor which 

 is objectionable for interior work where the building is closed. 



Pensacola Tar & Turpentine Co., Pensacola, Fla.: The solvent power of wood tur- 

 pentine is the same as the old fashioned article. It dries as well, and there is no differ- 

 ence in its working qualities. The only objection is that the odor is unpleasant. Its 

 power of absorbing oxygen seems to be equal to any turpentine. 



Naval Stores Supply Co., Biscoe, N. C.: We have been selling practically our entire 

 output to users of paints, and we suppose that this turpentine was used exactly as the
