Commonly known as \u003cstrong\u003eIT solder\u003c\/strong\u003e, it is formulated specifically for enameling applications. Each piece weighs approximately 5 pennyweights (5 DWT, or 1\/4 troy ounce) and contains \u003cstrong\u003e80% silver and 20% copper\u003c\/strong\u003e, with no zinc in the alloy.\u003c\/p\u003e\u003cp\u003eZinc can cause bubbling and surface defects when solder comes into contact with enamel during firing, which is why eutectic silver solders are the professional standard for enameled metalwork. The eutectic composition, silver and copper only, removes that risk and makes this solder the reliable choice wherever enamel and solder may interact. The approximate flow point is \u003cstrong\u003e1560°F (848°C)\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eZinc-free eutectic alloy, safe for use in enameling applications\u003c\/li\u003e\n\u003cli\u003eContains 80% silver and 20% copper only\u003c\/li\u003e\n\u003cli\u003ePrevents bubbling when solder contacts enamel during firing\u003c\/li\u003e\n\u003cli\u003eAlso known as IT solder in the trade\u003c\/li\u003e\n\u003cli\u003eApproximate flow point of 1560°F (848°C)\u003c\/li\u003e\n\u003cli\u003eSold as a single piece weighing approximately 5 DWT (1\/4 troy ounce)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eEach piece measures approximately 3-1\/2 inches long by 1-1\/4 inches wide.
