USES OF WOOD PULP. 



kind most in use is white, and a small quantity of brown wood pulp 

 also finds its way on the market. 



The chief disposition made of the pulp is in the manufacture of 

 the coarser kinds of printing and wrapping papers, when it is usually 

 mixed with a small quantity of cellulose, the substance chemically 

 produced from wood by boiling and lixiviation. 



Some 18,000 tons of the wood pulp made in this country are used 

 in the manufacture of pasteboard. 



The statement that wood pulp is being used in Vienna in the 

 manufacture of chairs and other articles of furniture is not alto- 

 gether correct. Numerous experiments in this line have been made 

 in Austria; but, in spite of all efforts, experience has proven that 

 the adaptation of wood pulp for other purposes than for paper and 

 pasteboard has not been commercially successful. Brown wood 

 pulp, sized, pressed, colored, and varnished, has been employed for 

 chair seats and also for the covering of walls in railroad carriages. 

 The white pulp has been used in making utensils of various kinds 

 and, in a less degree, frames and small decorative figures. At pres- 

 ent, utensils of wood pulp are manufactured in Europe for sale to 

 any extent only at Forbach, Lorraine. The employment of the 

 pulp in these ways has not been encouraging and is now practically 

 discontinued. Of course, experimenting still goes on; yet there 

 is no general or recognized use in this country for the wood pulp 

 outside of paper mills. As an instance in point, I may mention a 

 factory near Grein, Austria, where the brown pulp was subjected to 

 a special treatment of sizing and pressing. A pseudo leather was 

 turned out, called leatherette, and also waterproof wall hangings. 

 These efforts have been up to now only trials, as it has been shown 

 that articles of wood pulp are ineffective substitutes for leather, 

 linen, or wood. This same factory has made, from its sized water- 

 proof pulp, interior walls and also roofs for large barracks; but 

 these uses are also tentative, and experts are skeptical as to whether 

 the material can resist the action of the weather. 



Prof. Max Schubert, in his "Die Holzstoff- oder Holzschliff- 

 Fabrikation," a treatise of some 150 pages, which has appeared 

 within the month and which should be of interest to wood-pulp 

 manufacturers, speaks of two experiments that he made with waste 

 pulp extracted from the water used in the production of the pulj;. 

 Being obliged to filter the water used in the pulp making, large 

 masses of refuse pulp accumulated which were unfit to mix with 

 good wood pulp. To put the stuff to some practical use, he molded 

 brick-like blocks from the moist heaps. These blocks were at first 

 exposed to sun and air, and later thoroughly dried by artificial heat. 

 The result, Professor Schubert states, was a satisfactory building
