Frequently Asked Questions
Historically, it was used in varnishes, lacquers, adhesives, and polishes due to its ability to form a hard, durable film when dissolved in alcohol.
It is exuded from trees of the genus Xanthorrhoea, commonly known as grass trees, which are native to Australia.
Its use is very rare and mostly confined to specialist applications like art conservation or historical reproductions, having been largely replaced by modern synthetic resins.
The standard pronunciation is /əˈkrɔɪdiːz/ (uh-KROY-deez), with the primary stress on the second syllable.
