  • Steel doesn’t “anodize” in the sense that aluminum and some other metals do. However, it can be heat-colored. The trick is to clean the surface first (it must be oxide free), then heat gently until the colors appear.

    These are called “temper colors” in steel. They are due to a thin adherent layer of oxide that forms and thickens as temperature is increased. They are quite temperature dependent. As the steel is heated, the first color to appear is pale yellow. This will progress through darker yellows, browns, purples, and blues as the temperature rises. Above blue, the oxide becomes the gray/black color you are apparently getting – this is the result of heating too fast and too hot.

    See the chart at the site below for colors in plain carbon steel. Note that the temperatures are pretty low – It all starts around F and if you go above F the show’s all over.

    How to obtain a pure sample of solid MgSO?

    Answers Favorite AnswerYou have to get the MgO into a more usable form. To do this, add water to MgO first.MgO + HO ---> Mg(OH)Now you can use Mg(OH) with sulphuric acid.Mg(OH) + HSO ===> MgSO + HOI suppose it is possible to write it asMgO + HO + HSO ===> MgSO + HOMgO + HSO ===> MgSO + HO It should work.Add distilled water to the MgO so that it becomes Mg(OH). For simplicity it is best to use the sulfuric acid, since the only products other than magnesium sulphate would be water. The water can be removed by heating the solution until most of the water boils away. If you want anhydrous magnesium sulphate then you can heat the hydrated salt that is left.Other than take a bottle of magneisum sulfate from the shelf in my stockroom?React Mg(OH), which is called milk of magnesia, and HSO, sulfuric acid, stoichiometrically, and evaporate the water, allowing the MgSO salt to precipitate.Mg(OH)(s) + HSO(aq) --> MgSO(aq) + HO(l)
