Zircon Silicate powder is generally found inland of ancient coastlines, some of which can be found very far inland, where the heavier mineral sands formed hardened deposits. These deposits are typically mined via dry or wet (dredge) mining techniques.

We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.

Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills. It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color. Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating. From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list In particular the mill scale can be classified as follows: Einecs (european commission no.): 266-007-8 Waste code: 10 02 10 Basel code: b 12 30 Hs code: 2619.00
Tumi Ishi (pronounced Too-me Ee-she) are wood balancing blocks that are are meant to resemble stones. With so many different shapes and sizes, they are fun to hold and stack. These blocks make a great unique gift for that hard to shop for person. These also make beautiful and classy decorative pieces. Put them in a glass dish, stack them on your dining room table, coffee table, or desk.
