Since I was a beginner in stained glass, I struggled with the inconsistent finish color of antique patina and the lack of sparkle in silver finishes, and choosing solder was a constant worry. The antique patina would turn too reddish, and the silver finish would become too dark... When I asked the manufacturer, they said that solder doesn't really expire, but if it's too cheap, it might be recycled and contain many impurities. Also, the surface deteriorates over time, which affects the final finish. So! I ordered fresh solder. That's why it's brand new. Please see the manufacturing date in the photo. It's very easy to use, and the finish is not only shiny silver, but also the color of the antique patina and the black color are beautiful and very satisfying. Solder prices fluctuate depending on the market. This solder is high-quality and fresh, but it's not cheap. However, please finish your carefully crafted works beautifully with high-quality, fresh solder. I've purchased a large quantity, so I'm selling it in smaller portions. Please try it once. ※ Price negotiations are not possible.
