Scoria

Scoria is a highly vesicular, dark colored volcanic rock that may or may not contain crystals (phenocrysts). It is typically dark in color (generally dark brown, black or purplish red), and basaltic or andesitic in composition. Scoria is relatively low in density as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water. The holes or vesicles form when gases that were dissolved in the magma come out of solution as it erupts, creating bubbles in the molten rock, some of which are frozen in place as the rock cools and solidifies. Scoria may form as part of a lava flow, typically near its surface, or as fragmental ejecta (lapilli, blocks and bombs), for instance in Strombolian eruptions that form steep-sided scoria cones. Most scoria is composed of glassy fragments, and may contain phenocrysts. The word scoria comes from the Greek σκωρία, skōria, rust. An old name for scoria is cinder.

Escoria

José Ibarra is a Mexican Luchador (wrestler) who is best known as Escoria / Dark Escoria (Spanish for "Dreg"), a face character that works for Asistencia Asesoría y Administración (AAA). Ibarra has been part of The Black Family since it was formed, but left the stable in October 2010. During his time in the Black Family, Escoria was also a member of Lucha Libre Latina (LLL) and La Secta del Mesias, its predecessor La Secta Cibernetica and La Legión Extranjera.

Professional wrestling career

Ibarra made his wrestling debut in 1998 after training with Blackman, Negro Sosa and Draco for over six months. It was not until 2000 where Ibarra adopted his Escoria (sometimes referred to as "Scoria") that he was successful in the ring.

The Black Family

In the early parts of 2001 Escoria teamed up with four other wrestlers that all used a similar gimmick, look and attitude as Cuervo to form the stable the Black Family. The other wrestlers were Charly Manson, Cuervo and Ozz. Early on in the stable's lifetime Charly Manson suffered a grave injury after falling from a ladder during a match which put Manson out of wrestling for a long period. The Black Family brought in Chessman to be the fourth member. Around the time of Chessman joining the Black Family became part of Lucha Libre Latina (LLL), the Mexican version of the New World Order, a group led by Chessman's long-time friend Cibernético. Even though they were part of a much larger group the four men still worked as a unit, a stable within the stable.
