Gallium

The National Justice Museum, previously known as the Galleries of Justice, is a popular visitor attraction in the Lace Market based in the historic Shire Hall and County Gaol.

The courtrooms date back to the 14th century and the gaol to at least 1449. Between 1832 and 1864, the Shire Hall was the place where public hangings were carried out; Richard Thomas Parker, a murderer, was the last person to be publicly hanged there. In 1877, Thomas Gray was hanged in a yard to the rear of the Shire Hall. The gaol closed in 1878.

The building was used as a police station from 1905 to 1985, and the Shire Hall was in use as Notitngham’s civil and criminal courts until Nottingham Crown Court opened in 1991.

This interactive museum takes visitors on a journey of justice through time with historical characters bringing events to life, like DR Massey the Gaol’s medical officer who can describe in gruesome detail what he witnessed when examining the prisoners.

Gallium is a soft, silvery metal used primarily in electronic circuits, semi-conducters and LED’s.

Most commercial Gallium is extracted as a by roduct of aluminium and zinc production.

Although it is a solid at room temperature it is still so soft that you could cut it with a knife.

It has a high boiling point, which makes it ideal for recording temperatures that would vaporise a thermometer.
