Down to Earth - - THE FORTNIGHT -

NAT­U­RAL CAUSES

Min­eral im­pu­ri­ties present in the mar­ble get ox­i­dised and cre­ate brown stains. Rains also have a weath­er­ing ef­fect on the mar­ble and have been no­ticed to cause chip­ping and crack­ing. The iron dow­els used to fix the mar­ble slabs on the build­ing get rusted and the rust flows down with rain, get­ting de­posited on the mar­ble.
