A NEW ALKALI PROCESS.
In several former notes and articles in these pages, we have spoken of
the severe crisis through which the old established, or "Leblanc,"
process has now for some years been passing. It is, in fact, pushed
well nigh out of the running by the newer process, known as the
"ammonia-soda" process, and would have had to give up the battle
before now were it not for the fact that one of its by-products,
bleaching powder, cannot, so far, be produced at all by the
ammonia-soda works. The bleaching powder trade has thus remained in
the hands of the workers of the Leblanc process, and its sale has
enabled them to cover much of the loss which they are suffering on the
manufacture of soda ash and caustic soda.
