here's the link to the pad that Linda is talking about

http://www.joannasheen.co.uk/craft-supplies/inkpads-stamping-accessories/brilliance-pigment-ink-pad/brilliance-ink-pad-graphite-black/

my personal choice (which doesn't make it right!) would be to use a Versamark embossing pad and black embossing powder - as I like having just the one pad I always use for embossing and choose a coloured embossing powder ....

but that's just me - there are always loads of ways to do things
