Baikalit 150x25x6 on the form

In formal terms, Baikalit is a siliceous rock - fine-grained quartzite (microquartzite) - with an aggregate structure of quartz grains 1.5-3 microns in size with sharp boundaries between these very grains. Baikalit arose in the field of attention of pattern makers (and after that, sharpeners of cutting tools), as well as technical jaspers and much more - at a time when a replacement for Arkansas stone was actively sought. There were many reasons for this - the rock in the quarries of Arkansas dried up and became worse in quality, there were interruptions in the supply of imported minerals due to the so-called. abrasive embargo, etc. But this is history. But as a result, today we have a whole range of abrasive natural stones one way or another comparable in efficiency with the Arkansas stone, which at one time served as the standard for the quality parameters of the finishing touchstone. Baikalite is one of the few minerals that has been able to surpass Arkansas in terms of its abrasive properties. With almost the same abrasive ability and composition, Baikalit has a much finer grain and works much cleaner than Arkansas in a finer finishing area. In view of the small reserves of the Baikalite rock, as well as the active opposition of the traditional supporters of Arkansas, it has not been widely used in industry, but has become a virtual legend in fine-tuning cutting tools. A bar of Baikalit in any sharpening set is rightfully considered one of the most valuable and sought-after stones.

This mineral received the name Baikalit at the place of its deposit and finds in the Baikal region. Baikalite has a color from light green to dark green with small color differences of the same shade with a fairly dense structure (7 on the Mohs scale), it can work with both water and oil. Since Baikalit does not emit its own suspension, it performs well when working with induced suspensions from third-party materials (nagura, metal oxides, for example, chromium oxide, calcined alumina, etc.). By practicing variations from suspensions, you can achieve various results in metal processing from amazing sharpness of the cutting edge to a small basement of the RC at the super finish, which is necessary for a comfortable shave.
