The buildings around the mine were later crushed by avalanches.
One of the Dougall bricks found by Grigoriy Ilin, also bore the Russian lettering “4 щ д”
The following information from Vladimir Smirnov, St Petersburg, is believed to be relevant to the above brickmark.
4 – Can stand for size or shape or degree of heat resistance
Д can also stand for Доменный, i.e. Blast-furnace
Letters Ш and Д at Russian firebricks means Shamot (Fireclay) and Dinas type (not less than 93% silicon dioxide (silica)). I have no idea how two alphabets appeared at one brickmark and which of them can indicate the origin of the sample.
So was this firebrick manufactured at Bonnyside, Scotland by James Dougall and also stamped with Russian cryllic lettering denoting that it is a Dinas fireclay brick. ( Note – SBH – I have not seen reference of Dougall specifically using Dinas fireclay, but ganister fireclay is associated with Dinas fireclay and certainly Dougalls manufactured bricks from ganister).
It is also entirely possible that this brick is another counterfeit of a UK manufactured brick as per these possible similar examples – click me
