Pewter is a soft, low-melting alloy that, in the past, often contained lead. While old and antique pewter items are notoriously difficult to repair, modern lead-free pewter can be mended using specialized techniques and materials.
Repairing Modern Pewter
Unlike their vintage counterparts, modern pewter pieces can be repaired using pewter solder. This process involves carefully cleaning the damaged surfaces, applying the solder with a soldering iron, and smoothing out any excess. It’s important to work slowly and use a light touch to avoid further damaging the delicate metal.
Choosing the Right Solder
When repairing pewter, it’s crucial to use a lead-free pewter solder specifically designed for the task. These solders have a lower melting point than the pewter itself, allowing you to make the repair without compromising the integrity of the original piece. Avoid using regular plumber’s solder, as it may contain lead and could contaminate the pewter.
Preparing the Surface
Before soldering, thoroughly clean the damaged areas to remove any dirt, oxidation, or other contaminants. Use fine-grit sandpaper or mild steel wool to gently buff the surface, taking care not to scratch or deform the pewter. Ensure the area is completely dry before proceeding with the repair.
Applying the Solder
With the soldering iron heated, carefully apply the pewter solder to the damaged area, allowing it to flow into the cracks or gaps. Work quickly and use a light touch to avoid melting the surrounding pewter. Hold the smaller piece in place until the solder has hardened, then fill any remaining gaps as needed.
Finishing the Repair
Once the solder has set, use fine-grit sandpaper to smooth the repaired area, blending it seamlessly with the rest of the piece. Follow up with a soft cotton cloth to remove any scratches or residue, leaving the pewter with a clean, polished appearance.
