ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...

Recovery of barrier pillar reserves during deep potash seam mining
Mining potash deposits at great depths is associated with increasing extraction losses. Conventional room-and-pillar mining systems that leave barrier pillars between panels prevent their subsequent recovery because of progressive stress accumulation and
