I am an artist from Italy doing various stuff with metal etching recently after buying our etching equipments from etchcut, They have given us a formula for silver etching, it works really well for us, so am sharing with you all 60% nitric acid with H2O ratio 1: 3 Temperature : 38 degree C We have a bought a rapid etcher which is a vertical spray etching machine , it sprays the chemical with equal pressure thus give equal and fast etching always I would also like to add that for etching silver you need a coating which should be string enough to hold it till you get the depth in silver, We are using their resist only as it comes along with the equipment but they said it is commonly available earlier I use to make Silver etched jewellery in 3-4 days now with help of exposure and rapid etcher i complete my job in one hour Caution: Nitric creates hazardous fumes, keep your protective gears on while using nitric acid Hope this info helps Alice
