SCRAG ENDS

[SIMON GABRIELOW]

Yes, in intaglio printing( etching) acids are used to bite the design onto metal. And area you do not wish to be eaten away by the acid is protected by a wax layer, or stopping out varnish.. this is a black sort of paint; or can even be a crayon like block, rubbed onto a heated plate, where it melts, and once cooled, the layer can be scratched into, so leaving the acid to eat into only the open metal area of design.. whereas the wax that is left, prevents the acid biting.

That is basically the principal as it stands. 🌝🌝🌝🌝🌝

That photo looks weirdly Photoshopped to me, particularly the blurry area on the left.

I did wonder, but generously put it down to too much reflection 😄
