Hi I have a problem some times when I am rolling out sterling silver on my rolling mill. Most of the time when I melt downy scrap all is ok. But sometimes I find that when rolling down some silver I have melted. I get what looks like very fine slivers of the silver lifting up. It's like the edges of the silver are delaminating.
The surface is very rough this is manly when rolling square wire.
Can any one give some pointers on how to stop this happening
Thank you in advance
