Sheets","description":"\u003cp\u003eSilver sheet solder for hard (torch) soldering and brazing of silver jewelry and metalwork. Each sheet weighs approximately 5 pennyweights (1\/4 troy ounce \/ 7.7 grams) and measures approximately 40 mm × 60 mm with a thickness of 0.30–0.33 mm. Choose from five flow points — Extra-Soft through Hard — to match the demands of new fabrication, repair work, or specialty applications such as enameling.\u003c\/p\u003e\n\n\u003cp\u003eThe grade names Extra-Soft, Soft, Medium, Medium-Hard, and Hard describe relative flow temperatures within this solder line. Each successive grade flows at a higher temperature, which generally produces a stronger bond. Note that flow point designations can vary between manufacturers; one maker's Medium may flow near another maker's Hard.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExtra-Soft\u003c\/strong\u003e solder (also called Extra-Easy) produces a pale yellow appearance and leaves a visible seam on silver.
