【Colorful  iron meteorite technology】It is made of pure natural meteorite by heating and coloring without using any dye. Slice of meteorite at high temperature, a thin oxidation interference film is formed on the surface of iron meteorite,and the metal microstructure shows different colors by using the optical interference effects.Because nickel is more stable than iron, the thickness of the oxide film of meteorite is different from that of nickel when it is oxidized in air. When the interference effect occurs, the reflection wavelength is also different, which corresponds to the pattern position.So seen from the human naked eye, it  can enbody the colorful Widmanstatten pattern.Note: This manufacturing engineering is not a simple gas furnace blue burning process. It requires expensive high frequency induction heating equipment. The heating temperature and oxidation atmosphere can be accurately controlled  which to make colorful colors. If the temperature is not controlled, it will be completely burnt into bluIsh gray and lack of colorful.Therefore, the colors you see are made by complex processes.

If you buy from my store, Represents you accept the rules of our store.
【Introduce】We are called Axiom meteorite factory. We have seven years of experience in cutting and  carving iron meteorites, We can also make other metal pendant, Like pure titanium or copper. We can make meteorite products as your order.
【OPEN CASE】Our store has automatically set that if you don't make the payment for 8 days, the CASE will automatically start.Since we have paid the list fee to ebay, the fee can only be refunded when the case is opened,I don't want to hurt you,i only want get back my list fee from eaby ,please understand me.

【Anti-rust】By default, all of our meteorites are covered with layers of resin to prevent rust. At the same time, it is covered with a small amount of grease to avoid rust in trans-oceanic transportation.We recommend that you store the meteorite in a sealed box containing Anhydrous calcium oxide after you receive the iron.Another option is to use a refrigerator to freeze the meteorite, where there is no liquid water to avoid rusting.We store meteorites this way throughout the year..Even so,you need  check maintenance regularly. If rust is found, use an organic solvent, such as acetone, to remove resin and antirust oil,rinse acetone with running water. then use dilute nitric acid to remove rust, or use other organic weak acids to remove rust.We do not support the return of the goods, you can not return the goods after rust removal.Iron meteorite will rust is a chemical property,You must pay constant attention to avoid rust.meteorite will rust is entropy increase,It requires a constant input of time and energy.
