Float glass is made by floating molten glass on molten tin, pioneered by Pilkington in 1950s. Process replaced traditional cylinder method used until 19th century. Henry Bessemer patented first automated glass manufacturing system in 1848
Resources are essential for crafting items, bases, and vehicles. Resources don't regenerate once collected. Large resources like metals and minerals can only be mined with front suit
Surface roughness is the quality of a surface not being smooth. Measured by deviations of normal vector from ideal form. Can be measured using profilometers with contact or optical methods
Bluing creates protective black oxide coating on steel to prevent rust. Process forms magnetite (Fe3O4) instead of easily flaking red oxide (Fe2O3). Black oxide provides minimal protection unless treated with oil
Specifies quality levels for fusion welded joints in steel, nickel, titanium and alloys. Applies to material thickness ≥ 0.5 mm. Covers butt welds and fillet welds, including partial-penetration ones. Excludes beam welding
Resource information available through regional filters. Resource planning crucial before territorial expansion. Trade agreements should be evaluated for profitability
