Kali is generally considered one of the consorts of Siva. Her name seems to be a female version of the word 'kala' (Sanskrit for 'dark', 'time' - time in this form being a euphemism for death - or 'devourer of time' ); it also means 'Black Female,' in contrast to her consort, Shiva, who is white.
A comparatively recent devotional movement largely conceives of Kali as a straightforwardly benevolent mother-goddess.
We often have brass figures of Kali in our Glastonbury shop.
