Prof Asko Parpola (Helsinki University) argues that the mirror was not known in Vedic India until it was introduced by the Persians in 600 BCE. offering a histo.basis to study the Vedic literature. Studia Orientalia Electronica vol. 7 (2019): 1-29.
This argument of Asko Parpola is countered in this monograph.
There are two Indo-European root words which link to the semantics of 'mirror': der(ep)- 'to see, mirror'; drych m. (*dr̥ksos) sight, mirror'. Cognate Meluhha pronunciation variants include:
Set 1: Pa. dappana -- m. ʻ mirror ʼ, Pk. dappaṇa -- m.; A. dāpan ʻ mirror ʼ, dāpani ʻ a bellmetal utensil used by groom in marriage ceremony ʼ; Si. dapaṇa, däp˚ ʻmirrorʼ. Addenda: darpaṇa -- : A. also spel. dāpon ʻ mirror ʼ.
Set 2: Pa. ādāsa -- , ˚aka -- m., Pk. ādaṁsa -- , ˚aga -- , āyaṁsa -- , ˚aga -- , āyāsa -- ; -- MIA. *ādariśa -- : Pk. ādarisa -- , āya˚ m.; Paš. rešó, Shum. reṣe (ṣ!), S. āhirī f., L. ārhī, a˚ f., WPah. jaun. ārśī
Archaeological evidence attests the production of high-tin-bronze mirrors, using cire perdue (lost-wax casting) technique in many parts of Eurasia including Sarasvati Civiization, dated to ca. 4th millennium BCE.
It is extraordinary that Asko Parpola makes a fallacious statement that the mirror was not known in Vedic India until it was introduced by the Persians in 600 BCE. The existence of a bronze mirror is attested from Balochistan and from sites such as Rakhigarhi and Dholavira.

Attested techniques of Aranmula high-tin-bronze mirror can certainly be traced to the Sarasvati Civilization tradition of creating metal alloys. In this context, I cite the work of Jainagesh Sekhar, et al, 2015, Ancient Metal Mirror Alloy Revisited: Quasicrystalline Nanoparticles Observed in JOM: the journal of the Minerals, Metals & Materials Society 67(12) · July 2015

Sources of tin from Ancient Far East, the largest tin belt of the globe created the Tin-Bronze revolution
Lloyd R. Weeks presents a detailed and cogently argued thesis that tin bronzes of the third and second millennia in the early metallurgy of Persian Gulf points to sources of tin from the East. He posits possible sources from north and east in Afghanistan or Central Asia. However, he fails to resolve the archaeological fact that not many tin-bronzes have been found in Central Asia where there is predominant presence of tin-bronzes in sites such as Tell Abraq (Persian Gulf). (Weeks, Lloyd R., 2003,Early metallurgy of the Persian Gulf, Boston, Brill Academic Publishers Embedded for ready reference.)

I agree with the analysis of TE Potts (Potts, TF, 1994, Mesopotamia and the East. An archaeological and historical stuydy of foreign relations ca. 3400-2000 BCE, Oxford Committee for Archaeology Monograph 37, Oxford) that the tin for the tin-bronzes of ANE was sourced from the East. I further venture to posit that the tin came from the largest tin belt of the globe, through seafaring merchants of Ancient Far East (the Himalayan river basins of Mekong, Irrawaddy and Salween) mediated by Ancient India trade guilds of 4th to 2nd millennia BCE.

Here is a small argument about the high tin-bronze of mirrors found in Barbar temple and in Sarasvati civilization areas mediated by the brilliant metalwmithy work of artisans from Mehi of Kulli Culture.
A bronze mirror is among the aṣṭamangala-s अष्ट-मङ्गलम् [अष्ट- गुणितं मङ्गलं शा. क. त.] a collection of eight auspicious things; according to some they are:-- मृगराजो वृषो नागः कलशो व्यञ्जनं तथा । वैजयन्ती तथा भेरी दीप इत्यष्टमङ्गलम् ॥ according to others लोके$स्मिन्मङ्गलान्यष्टौ ब्राह्मणो गौर्हुताशनः । हिरण्यं सर्पि- रादित्य आपो राजा तथाष्टमः ॥

Ancient Metal Mirror Alloy Revisited: Quasicrystalline Nanoparticles Observed
Abstract
This article presents, for the first time, evidence of nanocrystalline structure, through direct transmission electron microscopy (TEM) observations, in a Cu- 32 wt.% Sn alloy that has been made by an age-old, uniquely crafted casting process. This alloy has been used as a metal mirror for centuries. The TEM images also reveal five-sided projections of nano-particles. The convergent beam nano-diffraction patterns obtained from the nano-particles point to the nanophase being quasicrystalline, a feature that has never before been reported for a copper alloy, although there have been reports of the presence of icosahedral ‘clusters’ within large unit cell intermetallic phases. This observation has been substantiated by x-ray diffraction, wherein the observed peaks could be indexed to an icosahedral quasi-crystalline phase. The mirror alloy casting has been valued for its high hardness and high reflectance properties, both of which result from its unique internal microstructure that include nano-grains as well as quasi-crystallinity. We further postulate that this microstructure is a consequence of the raw materials used and the manufacturing process, including the choice of mold material. While the alloy consists primarily of copper and tin, impurity elements such as zinc, iron, sulfur, aluminum and nickel are also present, in individual amounts not exceeding one wt.%. It is believed that these trace impurities could have influenced the microstructure and, consequently, the properties of the metal mirror alloy.
