It strikes a balance between matrix removal and gentleness on the surface of the fossil, with a Moh’s Hardness of 3.5-4. It is particularly effective on shale, siltstone and limestone. The grains are predominantly angular, providing a moderately gentle cutting action. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"\"\u003eDolomite is a naturally occurring carbonate consisting of calcium carbonate and magnesium carbonate, and is often found with marble having been subjected to high temperatures and pressures during tectonic movements.\u003c\/p\u003e\n\u003cp class=\"\"\u003eWhilst it is enormously effective in fossil preparation when it’s flowing well, dolomite powder is often associated with clogging, clumping and producing large amounts of dust. It also generates a great deal of static and therefore clings to itself, the internal plumbing of your abrasive unit, and the sides of the tank. It must only be used with a super clean, dry air supply (check out the Dropout air filters!). Dolomite powder has a range of grain sizes (predominantly \u0026lt;40μm).

Iron powder is combustible, and not recommended for use within a blast cabinet with a light that isn't completely sealed from the environment. LED lights or external LED lights preferable. Chance of explosion is incredibly rare, and we supply a grade of iron powder with limited fines to mitigate this risk. Make sure that your dust extraction system is grounded.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"\/pages\/all-about-air-abrasives\"\u003eLearn more about air abrasive units here.\u003c\/a\u003e\u003c\/p\u003e","brand":"ZOIC PalaeoTech","offers":[{"title":"25kg \/ UK MAINLAND SHIPPING ONLY","offer_id":54995452428664,"sku":null,"price":135.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0252\/4695\/7631\/products\/IMG_9958__29396.1592384510.1280.1280.jpg?v=1614514847"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0252\/4695\/7631\/collections\/IRON_POWDER_2.jpg?v=1613917958","url":"https:\/\/www.zoicpaleotech.com\/collections\/air-abrasive-powders\/iron-powder.oembed","provider":"ZOIC PalaeoTech Limited","version":"1.0","type":"link"}
