Martha Stewart Crafts - Glitter Embossing Powder - Sterling

Not the color I thought it was

I bought this for use on the edges of small business card/"thank you for your purchase" cards I put in with orders. I make sterling silver jewelry with a multimedia, steampunk, rock & roll twist. I use lots of sterling silver wire and thought my cards would look great with a sterling silver edge.

This embossing powder turns an odd shade of silver, but it isn't the shiny sterling silver color I was expecting. After running the heat tool over it, I watched it melt and pulled the tool away, the color was a frosty gray. Thinking I didn't hold it there long enough, I hit it with the heat again, it melted and started to bubble so I pulled the heat away.
I came out more like a gunmetal than a pure sterling silver.
I will still use the powder probably on card pieces before I resin them, but I won't use it on my business cards.
