Copper Metal Powder Very Fine 240 Mesh For Cold Casting > 99.5% pure

Very fine Copper powder for use with most casting resins. Also used for cold cast Copper effects.

 Can be used with my reactive copper paint to add additional interest or areas that you want to have move patina

As an approximate guide the minimum ratio would be a 1:1 mix for the metal powders, for every 100g of metal powder to every 100g of resin but this is up to the user to decide based on the actual use
