protilers
calibrated means each tile is the same thickness i.e 10mm.
rectified means they are the same size i.e 305 x 305
dead flat means you want "honed slate" like what they use under snooker tables!!!!
if you want it with a texture you need to buy "riven" slate.
P.s always buy calobrated slate,uncalobrated slate is cheaper to purchase, but it will cost you a lot more in adhesive and labour due to the extra work involved in getting a solid bed of adhesive!!!!!!!! unless the tiler is chancing his luck!, all professionals will qoute a higher price for tiles that are not square and/or not equal thickness.....good luck!
