Black film on sterling is silver sulphide, and it forms wherever sulphur reaches the surface. Household sources are everywhere: wool drawers, rubber bands, latex, some paints, gas appliances, egg yolks, and the sulphur compounds in your own perspiration. Two people can own identical pieces and see completely different results based on storage and skin chemistry. Silver tarnish removal fixes the symptom, while airtight storage with anti-tarnish strips addresses the cause.

Fire scale is copper oxide that forms inside the alloy when sterling is heated with oxygen present. It surfaces later as a grey or purplish shadow under the polish, and no amount of buffing removes it once it is deep. We prevent it with boric acid firecoat, controlled flame time, and repeated pickle cycles. Repairs done without that discipline look fine leaving the bench and turn cloudy months afterward.

Usually not all of it. Chased, engraved, and repoussé work depends on dark recesses for contrast, and a piece polished uniformly bright loses the depth its maker designed in. We clean raised surfaces, leave the depths intact, and mask hallmarks so they stay crisp. If you want full brightness we will do it, though the decision cannot be reversed.

Silver work hardens. Every flex rearranges the crystal structure a little more until the metal loses its ability to move and fails instead. Cuffs, bangles, and thin shanks are the usual casualties. Annealing resets that hardness with controlled heat, after which we close the crack and re-harden the finished piece so it holds shape again.

It does, and it stops tarnish entirely for as long as the plating lasts, since air never reaches the silver. The trade-off is appearance: rhodium reads brighter and harder than sterling, so the warm quality some people love disappears. Plating on rings worn daily typically needs redoing every year or two. Pieces worn occasionally hold much longer.

You cannot tell reliably by eye, which is why every intake starts with a hallmark read plus acid or XRF testing. Sterling is .925, Britannia is .958 and noticeably softer, Argentium contains germanium and resists both tarnish and fire scale, and coin silver runs about .900. Silver plate is base metal under a microns-thin skin. Soldering plate usually burns straight through it, so those pieces get replating advice instead.

Yes. Deliberate oxidation is a liver of sulphur patina, and any torch work or home polish destroys it. We re-oxidise the repaired area, match the depth against untouched sections, then relieve the high points by hand so texture reads properly. Tell us at drop-off if the dark finish is intentional, because otherwise it looks like tarnish to be removed.

Both are abrasives, and both remove metal along with tarnish. Repeated use rounds off engraving, softens hallmarks, and leaves a haze of fine scratches that catches dirt faster than before. Aluminum foil and baking soda baths also strip intentional patina indiscriminately. Warm water, mild soap, and a soft cloth are safe at home. Anything past that belongs on a bench.

Airtight is what matters. Zip bags with the air pressed out, or a sealed box with anti-tarnish strips, will keep sterling bright for years. Keep silver away from wool, felt, rubber bands, and cardboard, since all of them release sulphur. Store pieces separately so harder settings do not scratch softer surfaces. Skip the open dish on the dresser if tarnish bothers you.

Usually, though the match is easier when you tell us what the finish is. Satin, florentine, hammered, brushed, and sandblasted surfaces all need rebuilding by hand after any solder work, because polishing a repair area smooth leaves an obvious bright patch. Bring photographs of the piece before the damage if you have them. Matching texture is craft work, and it is the part that separates an invisible repair from a visible one.

The copper in sterling reacts with moisture and skin acids, and the compound it forms transfers to skin. Nothing is wrong with the ring, and nothing is wrong with you. Lotions, sunscreen, and humid weather all accelerate it. A rhodium or clear protective coating puts a barrier between the alloy and your skin, though the coating wears and needs redoing. Removing the ring before hand washing helps more than people expect.

Silver by weight is rarely the reason to repair a piece, and we will say so plainly if a repair costs more than replacement. What justifies the bench time is provenance, design, or the fact that it belonged to someone. Sterling silver restoration makes sense on antiques, designer work, and family pieces. For a plain modern chain, replacement often wins, and we will tell you that upfront.
