    In the era of commercial wrought iron, blooms were slag-riddled iron castings poured in a bloomery before being worked into wrought iron. In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than 36 in 2 (230 cm 2).

  4. Direct reduced iron - Wikipedia

    en.wikipedia.org/wiki/Direct_reduced_iron

    Direct-reduced iron has about the same iron content as pig iron, typically 90–94% total iron (depending on the quality of the raw ore) so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel. Hot-briquetted iron ...

  6. Telluric iron - Wikipedia

    en.wikipedia.org/wiki/Telluric_iron

    Telluric iron is largely divided into two groups, depending on the carbon content. Type 1 is a cast-iron typically containing over 2.0% carbon, while type 2 ranges somewhere between wrought iron and a eutectoid steel. Both types tend to handle weathering in the elements very well, but tend to decompose and crumble very quickly in the dry ...

    What Is Granite? Whereas quartz countertops are man-made, granite is a naturally occurring stone, quarried from the earth, then cut and polished into the countertop material so many know and love ...

  8. Mineral redox buffer - Wikipedia

    en.wikipedia.org/wiki/Mineral_redox_buffer

    For instance, at redox conditions more oxidizing than the MH (magnetite-hematite) buffer, at least much of the iron is likely to be present as Fe 3+ and hematite is a likely mineral in iron-bearing rocks. Iron may only enter minerals such as olivine if it is present as Fe 2+; Fe 3+ cannot enter the lattice of fayalite olivine.

  9. Countertop - Wikipedia

    en.wikipedia.org/wiki/Countertop

    Countertops are custom made and more scratch resistant as well as less porous than natural quartz surfaces, and don't need to be sealed like other stone surfaces. Due to the presence of the resins, quartz counters are less prone to staining. Thicknesses may be 6mm, 1.2 cm (1/2 inch), 2 cm (3/4 inch), 3 cm (1¼ inch) or 4 cm (1½ inch).
