Hello Mike in Michigan,
In answer to your question about ordering sterling sheet on line
and pricing 14K casting grain: go to the Rio Grande website
http://www.riogrande.com/ordering.htm#catalogs and order their gems
and findings catalog. There is a $10.00 charge, but you get a
$10.00 certificate to use on your first order. In addition to
printed example prices/dwt on precious metals, the catalog has
instructions that show you how to calculate the actual cost of all
their metals based on the current market price. You will notice that
the cost/dwt changes with volume, so giving you a rough estimate is
difficult without knowing how much you want to buy and the current
price. Once you have the catalog, you can order online.
If you qualify to buy wholesale, go to Stuller's website:
http://www.stuller.com/ and register. Request catalogs also.
Their findings book is a very handy tech reference as well as a
listing of all their metals. Stuller's on-line ordering works well
and you can see current pricing on what you purchase. Not to mention
their stellar reliable and speedy shipping!
Hope this helps, Judy in Kansas
