A bronze plaque's corrosion pattern in Georgia usually points straight back to whatever industry or soil sits nearest the cemetery — pulp mill exhaust, decaying pecan hulls, red clay runoff, or plain irrigation water. Tending restores bronze grave markers statewide, backed by $2,000,000 in liability insurance and membership in the ICCFA. Reading that pattern correctly before the first solvent touches the plaque is what keeps a restoration from turning into a second strip a year later.
Pulp Mill Sulfur Near the Mill Belt
Georgia is one of the country's top pulp and paper producing states, with kraft mills running from Rome down through Savannah and Brunswick, and the kraft process releases reduced sulfur compounds — hydrogen sulfide among them — as a normal part of production, the same chemistry behind the industry's well-known odor. That sulfur reacts with bare copper alloy the same way it reacts with silver, forming a dense black copper sulfide layer once it works past a weak point in the factory clear coat. Cemeteries downwind of an active mill tend to need a more thorough strip than the softer green patina a plaque develops without that sulfur exposure. Tending's technicians grade the corrosion from submitted photos before choosing a solvent, since sulfide tarnish responds differently than plain oxidation.
Pecan Hull Staining in South Georgia
South Georgia grows more pecans than any other state in the country, and orchard-adjacent cemeteries end up with decaying hulls scattered across the ground after harvest. As those hulls break down, the tannins inside them react with the bronze surface, leaving a mottled dark stain rather than the even green patina normal weathering produces — the same chemistry behind old iron-gall ink, just working on a copper alloy instead of paper. The stain sits on top of whatever finish is already failing underneath it, so a plaque near an orchard often looks worse than its actual corrosion level once that surface staining is cleared away. A rigid nylon block, not a wire brush, levels the discoloration without stripping sound patina along with it.
Red Clay Runoff Onto the Plate
A hard Georgia thunderstorm can splash red clay directly across a flat bronze marker, and the iron oxide that gives the clay its color leaves a rust-toned residue once the water dries. Left alone through a few storm cycles, that residue works into any gap in the clear coat and accelerates oxidation underneath it rather than just sitting on the surface as dirt would. Chelating agents formulated to bind iron are what actually lift it, since plain water and scrubbing tend to spread the stain deeper into the metal's surface texture instead of removing it. Tending's crews use that targeted approach on Piedmont and clay-belt cemeteries specifically, rather than reaching for a generic all-purpose cleaner that leaves the iron bound to the plaque.
Hard Water Scale from Cemetery Irrigation
Cemetery sprinkler systems running on untreated municipal or well water leave calcium carbonate behind every time the spray evaporates off a flat marker in Georgia's heat. That mineral scale builds into a chalky white crust that can obscure engraved dates within a single growing season, especially on markers positioned under a sprinkler head's regular path. An acidic descaler dissolves the calcium bond without touching the bronze underneath, and a low-pressure rinse clears the loosened residue before the surface is refinished. Markers set further from a sprinkler line rarely see this pattern at all, which is part of why the same cemetery can show scale on some plaques and none on others just a few rows over.
Bronze Grave Marker Restoration Costs in Georgia
Photos of the plaque and its corrosion go into the Tending calculator, and the price that comes back is based on plaque size and how far the corrosion has progressed — sulfide, tannin staining, iron residue, or scale — not on which part of Georgia the marker sits in. That number holds through the job. Once the plaque is stripped, refinished, and sealed, before-and-after photos go into the app, so the result can be checked without a return trip to the cemetery.
How Our Bronze Refinishing Process Works
- Photo-Based Corrosion Grading A technician grades the corrosion from submitted photos, sulfide blackening, tannin staining, iron residue, or mineral scale, and masks the surrounding stone before any solvent goes on.
- Targeted Stripping The failed coating and surface staining come off with a solvent matched to that specific corrosion, taking the plaque down to bare copper-tin-zinc alloy while leaving sound patina intact rather than sanding it away.
- Recontrasting the Inscription Fresh paint goes back into the recessed lettering, and the raised letters get worked to bright metal so the inscription reads with contrast again.
- Microcrystalline Wax Sealing A microcrystalline wax coat replaces whatever finish failed, and that seal is what actually determines how the plaque holds up against the next round of sulfur, tannin, or clay exposure. Finished photos go into the <a href='/app/'>Tending app</a> once the wax cures.
