Shot silk

==Description==
A type of taffeta fabric in which different colors are used for silk warp and weft yarns. Shot silk has an iridescent appearance and was used as early as the 7th century. It is currently used for neckties and academic robes. The technique is also used with Polyester, Acetate and Rayon. The term 'shot' is also used to refer to the use of metallic threads added to the weave.

Shotcrete

== Description ==
A concrete mixture that is sprayed at high velocity onto a surface. Shotcrete is also called Gunite from an early brand name. Shotcrete is composed of the same materials (cement, sand, aggregate and water) used for poured-in-place concrete. It can be applied by a wet-mix process in which the water is added prior to dispensing or by a dry-mix process in which the water is mixed in the nozzle during delivery. A patent for the first concrete sprayer was obtained in 1908 by Carl Akeley at the Field Museum of Natural History in Chicago. Shotcrete was used to apply thin layers to steel reinforced masonry sections, to coat building exteriors and to repair deteriorated stucco. Because it could be applied to vertical and overhead locations, it was also used to construct domes and shell roofs. The force produced as the concrete is propelled onto the surface negated any need for compacting the mixture. Cracking and debonding are seen in deteriorated shotcrete as well as corrosion of reinforcing bars.
== Synonyms and Related Terms ==
betão projectado (Port.);
Brand names: Gunite

Siccative

== Description ==
A substance that catalyzes the drying of oil-based paints, alkyd paints, varnishes and inks via free-radical autoxidation of the oils with air. Siccatives (also called driers) are usually metallic salts of organic acids (i.e., metal soaps). Examples are cobalt linoleate, cobalt oleate, and cobalt naphthenate. Organic acid salts of most heavy metals, such as manganese, cerium, lead, chromium, iron, zinc and zirconium, can also be effective driers. Some pigments also act as driers, such as lead oxide and manganese oxide. In recent years nonmetallic driers, such as orthophenathroline, are being used as replacement for the toxic heavy metal driers.
== Synonyms and Related Terms ==
drier; dryer; drying agent; cobalt drier; 
== Risks ==
* Heavy metal compounds are toxic by ingestion and inhalation. 
* Excess driers can cause surface skinning and wrinkling.

Sicilian sumac

== Description ==
A small tree, Rhus coriaria, native to Europe, whose leaves, bark and roots were used for dyes and tannins. The bark from the tree gives a fugitive pale yellow color when mordanted with alum but produces a strong black color with iron. Also called tanner's sumac, it was an important tanning agent in the Middle Ages.

Siderin yellow

== Description ==
A yellow pigment composed of iron chromate. Iron chromate is precipitated from a solution of a chromate salt, such as potassium dichromate by the addition of ferric chloride. The pure pigment is bright yellow, but some residual impurities, such as iron oxide, may result in a dull orange pigment color. Siderin yellow is compatible with all paint binders. It has also been used as a brown ceramic glaze and as a colorant in glass and enamel.
== Synonyms and Related Terms ==
iron chromate; ferric chromate; Pigment Yellow 45; CI 77505
== Risks ==
* Human carcinogen. 
* Skin contact may cause allergies. 
* Acute ingestion may cause fatal chromium poisoning.
