WHAT IS ETCHING
It is the processing of engraving (metal, glass, or stone) by coating it with a protective layer, drawing on it with a needle, and then covering it with acid to attack the parts the needle has exposed, especially in order to produce prints from it. – The acid corrodes or eat away the exposed (with Needle) parts.The etching process is known as biting .The waxy resist prevents the acid from biting the parts of the plate which have been covered.The longer the plate remains in the acid the deeper the “bites” become.
