I found your contact information from a search on the internet. I am a fellow woodturner and have obtained a bulk of copper powder and Man Made Turquoise. I would like to offer some of what I have for sale to other turners. These materials add a great look to turned items. See more at http://www.walstonwoodworks.com/. Copper Powder 1 lb $13.00 plus shipping. Man-made turquoise 1 lb from $11.50 to $13.50 plus shipping.
These items can also be found on ebay by searching Blue Turquoise Man Made, Copper Powder Rose.
Thanks for your time.
