Regularly strip away lustre when breaking tektite (10)

I believe the answer is:

australite

I'm a little stuck... Click here to teach me more about this clue!

'tektite' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's an association between them I don't understand?

'regularly strip away lustre when breaking' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'when breaking' is an anagram indicator.
'strip'+'away'='stripaway'
The alternating letters of 'stripaway' are 'tiaa'.
'tiaa'+'lustre'='tiaalustre'
'tiaalustre' is an anagram of 'AUSTRALITE'.

Can you help me to learn more?
