This recent?noticed today blue/grey drybrushing of concrete and 70s?80s?90s metal fences the example on francis footpath fences =
= lead

Almost thought blue stone/stones were ore?rock full of lead mineral?though think that is maybe incorrect though instead could be flint like in cigarette lighters and maybe cavemen flint rocks/stones

Also thought that maybe lead has something to do with magnets? And possibly all magnets are lead?magnesium came to mind typeing that maybe only due dyslexia though yeah electronics defineately have lead so electro-magnets and almost all or every circuit board has lead ?mercury??? Welds from soldiering irons ~

~must be more dyslexia due to the forty5plus70s80s60s? Lead soldiers the metal army men toys figurenes like that of modern day GamesWorkshop'$ Warhammer $ & Warhammers 40k anyway,
