<kānta:: parīkṣā>
pātre yasminprasarati jale tailabindurna lipto hiṅgurgandhaṃ visṛjati nijaṃ tiktatāṃ nimbakalkaḥ /
pāke dugdhaṃ bhavati śikharākāratāṃ naiti bhūmau kāntaṃ lohaṃ tadidamuditaṃ lakṣaṇairnaiva cānyat //

In a vessel containing water in which a drop of oil does not spread; asafetida smeared [on it] sheds its scent; neem paste sheds its bitterness; / when boiled, milk forms a peak-like shape and does not run onto the ground—that is proclaimed kānta iron by its characteristics, and nothing else.
