Can I etch silver using salt? Answered

No, regular table salt (NaCl) will not etch silver at all. The best you could possibly hope for would be a microscopically thin layer of Silver Chloride on your etch lines, which would prevent any further etching. Even that's not terribly likely.
Your best bet for safely etching silver is Ferric Nitrate. Here's a supplier (US and Canada only).

I think not. Silver is one of those metals that's quite resistant to corrosion.
What do you want - surface patterning or etched right through?

Surface etching - but I was wanting to avoid using acid.  Thanks for your response though.
