Anisotropy

We still need to find appropriate qualifiers for this property and gather them here. I don't think we have any properties yet to define anisotropy of a material. --Tobias1984 (talk) 23:39, 31 January 2014 (UTC)

@Tobias1984: I think anisotropy could be marked with a direction (P560) and the greek letter, like in epsomite (Q411430) -Theklan (talk) 14:33, 21 May 2017 (UTC)
