The process invented for this purpose consisted of first grinding the blacklead to powder as soon as it came out of the mine, then purifying it as much as possible from foreign substances by chemical means and finally compressing it by means of a press in such a manner that the mass could be just as easily cut as the pure Cumberland blacklead used to be. However notwithstanding all the appliances of art and science were brought to bear upon the subject and spite of every exertion to render this composition perfect, the English have not hitherto succeeded in producing any material capable of replacing the natural blacklead as obtained from the Cumberland mines.
These circumstances operated as an inducement to search for a substitute, which would admit of a greater economy in the use of blacklead. Experiments were made in England with this view and various substances such as glue, isinglass, tragacanth, gum &c. were tried for the purpose of cementing and consolidating the earthy blacklead into a firm mass. But none of these means succeeded. Subsequently it was attempted to improve the blacklead by melting it with minerals, compounding it with 30 or 40 per cent of sulphur. But this made the blacklead too brittle and the pencils made by this process would hardly mark at all. At last mixing with antimony was tried, which certainly yielded a composition in outward appearance very similar to the pure blacklead, but which proved to be but an unsatisfactory writingmaterial.
Towards the end of last century the manufacture of leadpencils was introduced into France and soon attained to an extensive developement. Hardly were the last restrictions upon industrial freedom removed in that country, when in the year 1795 the idea was started of making use of clay for the purpose of binding the blacklead together. This process soon found favor on account of its many advantages for by this commixture a great portion of the costly blacklead was saved and at the same time the manufacture rendered materially easier, so that the leadpencils could be supplied at a very much cheaper rate.
By these novel improvements a fresh era in the manufacture of leadpencils was commenced in France. Notwithstanding this however, there was yet very much to be done in the department of blackleadpencil manufacture in order to keep pace with the increased requirements of advancing art and more civilised life.
True, various degrees of hardness and different sorts of pencils were thus obtained but these were by no means proportional to the various modes of use. The manipulation of the brittle material demanded deep study, and conscientious laborers in order to give the pencil the requisite perfection.
If we now turn to Germany, it will in the first place be necessary to cast a glance at the developement of German industry and German leadpencil manufacture, it being then shown under what circumstances it had to develope itself and with what rivals it had to enter into competition.
It is not to be denied that from the very first German industry found itself in a more disadvantageous position. France and England had already become intrinsically industrious countries. They possessed immense facilities for foreign trade, the greatest internal freedom of motion for the industrial element, a legislature which took cognizance of all the requirements of industry, in short both countries were, in comparison with Germany, favored by certain circumstances which are indispensably necessary to render industry flourishing and which were then already fulfilled, whereas in Germany political division and animosity and the pressure of the guilds operated most perniciously upon industrial enterprise.
For these reasons industry could only develope itself in Germany later and then but slowly. The transition from the old to the new state of things appeared much more difficult, as many long since antiquated forms, which had become endeared to us by use, had first to be abolished.
The Saxon spirit, which, on the other side of the Channel had attained to such glorious results, had to sustain many a conflict in its native land, and many a praiseworthy attempt suffered shipwreck on the many obstacles, which the splitting up of the nation and the retention of unfeasable arrangements opposed to every great idea.
German science flourished at the same time to a very great extent, but in its exaltation it stood too high above ordinary life, not perceiving how to associate itself with it, so as to penetrate it with its enlightening and warmthgiving rays. Thus German industry remained far behind foreign enterprise and Germany beheld herself inundated with quantities of foreign manufactures, which she herself could have produced just as well, indeed it came to such a pass that foreigners relying upon their well organised commerce and the celebrity of their products even ventured to send German manufactures into the German market, stamped with a foreign trademark.
