I will have a go at using many different materials as bases when building collagraph plates but this was perhaps the most challenging!
This collagraph on paper was printed from a plate that was created out of masking tape, aluminium tape and pressed seaweed on a piece of roofing slate left over from reroofing our house.
Making the plate was relatively easy but printing from it was going to be a challenge as I did not know whether the slate was going to crack & splinter under the pressure of the rollers.
However by carefully adjusting the pressure of the rollers & using lots of soft materials below the plate, an image was successfully transferred onto paper & the slate survived the process,
with only a few little bits broken off the edge.
I will definitely be using slate again for the base of a collagraph plate as I love the textures achieved by inking with rollers.
