Yellow Cross (Gelbkreuz) is a World War I chemical warfare agent usually based on sulfur mustard (HS, Yperite, Lost).
The original Gelbkreuz was a composition of 80-90% of sulfur mustard and 10-20% of tetrachloromethane or chlorobenzene as a solvent which lowered its viscosity and acted as an antifreeze, or, alternatively, 80% sulfur mustard, 10% bis(chloromethyl) ether, and 10% tetrachloromethane. A later formulation, Gelbkreuz 1, was a mixture of 40% ethyldichloroarsine, 40% ethyldibromoarsine, and 20% of bis(chloromethyl) ether. In some cases nitrobenzene was used to mask the material's characteristic odor. French "ypérite no.20" was a similar mixture of 80% sulfur mustard and 20% tetrachloromethane.
Yellow Cross is also a generic World War I German marking for artillery shells with chemical payload affecting exposed surfaces of the body.
Famous quotes containing the words yellow and/or cross:
“Come unto these yellow sands,
And then take hands.
Curtsied when you have and kissed
The wild waves whist,
Foot it featly here and there;
And, sweet sprites, the burden bear.”
—William Shakespeare (1564–1616)
“All pathways by His feet are worn,
His strong heart stirs the ever-beating sea;
His crown of thorns is twined with every thorn;
His cross is every tree.”
—Joseph Mary Plunkett (1887–1916)
