Creosote removed; the "heavy oil", which sinks; and the "anthracene oil", which when cold is mostly solid and greasy, of a buttery consistence. Creosote refers to the portion of coal tar which distills as "heavy oil", typically between 230–270 °C, also called "dead oil"; it sinks into water but still is fairly liquid. Carbolic acid is produced in the second fraction of distillation and is often distilled into what is referred to as "carbolic oil". Commercial creosote will contain substances from six groups. The two groups occur in the greatest amounts and are the products of the distillation process—the "tar acids",

Hoorens and Todorova tested this by looking for a name-letter effect in bilingual subjects where their mother tongue alphabet was Cyrillic and their foreign-language alphabet Roman. Because learning a foreign language at a later age does not typically involve extra attention given to name letters, there should be no name-letter effect in the foreign-language alphabet, only in the first-language alphabet.
