<p>[QUOTE=&quot;Publius2, post: 24664425, member: 105571&quot;]Definitely a cold pour.&nbsp; So, some questions pointing to things to look at:</p><p><br /></p><p>1)&nbsp; How are you measuring temperature? The melt temperature measurement should be as close to a uniform throughout the melt as possible.</p><p><br /></p><p>2)&nbsp; Silver melting temp is about 1760F.&nbsp; If the raw silver has an alloying agent it is most likely copper.&nbsp; That temperature is a touch less than 2000F.&nbsp;&nbsp; If there is copper in your melt and you haven&#039;t raised the temperature above 2000F and held it long enough to thoroughly melt the copper, then you will have a cold pour.</p><p><br /></p><p>3)&nbsp; You have to hold the melt at your desired final temperature for a little while to allow any contaminants and alloying elements to separate.&nbsp; Some of those will sink and some will rise.&nbsp; Those that rise should be skimmed off.&nbsp; I use a SS skimmer for that.&nbsp; But don&#039;t hold at temperature for too long because oxidation is dramatically increased at higher and melt temperatures.&nbsp; It&#039;s a bit of an art.</p><p><br /></p><p>I developed my methods using aluminum to cast parts for my various projects.&nbsp; I learned much of the basics from an old Yahoo Group on the subject.&nbsp; Today, I am sure YouTube has superseded that venue so you should be able to get a lot of tips.</p><p><br /></p><p>Be careful.&nbsp; Wear good eye and face protection.&nbsp; I set fire to myself and almost lost an eye when a gob of molten aluminum shot out of the melt and hit my shoulder.&nbsp; If I hadn&#039;t dodged, it would have hit me in the face.[/QUOTE]</p><p><br /></p>
