Hem detail with inscriptions, Saint-John in Crucifixion, Ferrara, by Vicino da Ferrara (1469–70). A hem in sewing is a garment finishing method, where the edge of a piece of cloth is folded and sewn to prevent unravelling of the fabric and to adjust the length of the piece in garments, such as at the end of the sleeve or the bottom of the garment.
Visible mending is a form of repair work, usually on textile items, that is deliberately left visible (compare to invisible mending).The dual goals of this practice are to adorn the item, and to attract attention to the fact it has been mended in some way.
The hemline is the line formed by the lower edge of a garment, such as a skirt, dress or coat, measured from the floor. [1] The hemline is perhaps the most variable style line in fashion, changing shape and ranging in height from hip-high to floor-length. What is a fashionable style and height of hemline has varied considerably throughout the ...
The hemline index is a theory that suggests that skirt length (hemlines) rise or fall along with stock prices. The most common version of the theory is that skirt lengths get shorter in good economic times (1920s, 1960s) [ 1 ] and longer in bad, such as after the 1929 Wall Street crash .
An abstract conceptual overview graph of changes in hemline heights (skirt lengths) in middle- and upper-class western women's clothes over two hundred years (1805-2005). The curve in this image is not based on exact numerical data, but instead presents a summary of broad general trends (i.e. the graph is more qualitative than quantitative, or ...
Ironstone (sandstone with iron oxides) from the Mississippian Breathitt Formation, Mile Marker 166, I-64, Kentucky. Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially.
Cast iron development lagged in Europe because wrought iron was the desired product and the intermediate step of producing cast iron involved an expensive blast furnace and further refining of pig iron to cast iron, which then required a labor and capital intensive conversion to wrought iron.
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.
