The reference to this pot in an archaeological context is detailed by Mortimer Wheeler from -16:31 to -15:44 of the video presented herein.

This signifies brass ingot dula 'two' rebus: dul 'metal casting' PLUS kuṭi 'curve;  kuṭika— 'bent' MBh. Rebus: kuṭila, katthīl = bronze (8 parts copper and 2 parts tin) bhaṭa ‘warrior’ rebus: baṭa‘iron’ (Gujarati)

Sign 15 This is composed of Sign 12 and Sign 342 This Hypertext Sign 15 signifies kuṭhi kaṇḍa kanka ‘smelting furnace account (scribe)’. 

It will be seen from Sign 15 that the basic framework of a water-carrier hieroglyph (Sign 12) is superscripted with another hieroglyph component, Sign 342: 'Rim of jar' to result in Sign 15. Thus, Sign 15 is composed of two hieroglyph components: Sign 12 'water-carrier' hieroglyph; Sign 342: "rim-of-jar' hieroglyph (which constitutes the inscription on Daimabad Seal 1).

kaṇḍ kanka ‘rim of jar’; Rebus: karṇaka ‘scribe’; kaṇḍ ‘furnace, fire-altar’. Thus the ligatured Glyph is decoded: kaṇḍ karṇaka ‘furnace scribe'
Daimabad Seal 1 (Sign 342: Two hieroglyph components: jar with short-neck and rim-of-jar) -- distringuished from broad-mouthed rimless pot which is another Sign hieroglyph.

Each hieroglyph component of Sign 15 is read in rebus-metonymy-layered-meluhha-cipher:  Hieroglyph component 1: kuṭi 'woman water-carrier' rebus: kuṭhi 'smelter' furnace for iron/kuṭila, 'tin metal'. Hieroglyph component 2: kanka, kārṇī-ka 'rim-of-jar' rebus: kanka, kārṇī-ka m. ʻsupercargo of a shipʼ 'scribe'.

 This hypertext signifies the hypertext reads: dul kuṭila 'cast brass' (from) bhaṭa 'warrior' Rebus: bhaṭa 'furnace'.

The two parenthetical marks which constitute the circumscript around the ''warrior' hieroglyph are a split lozenge or oval shape Sign 373which is an Indus Script Sign.

Decipherment of Harappa zebu figurine with oval spots: magnetite ingots http://tinyurl.com/o75bok6 wherein a zebu figurine with oval spots has been presented.

I submit that these oval spots signify पोलाद pōlāda, 'crucible steel cake' explained also as mūhā mẽṛhẽt = iron smelted by the Kolhes and formed into an equilateral lump a little pointed at each of four ends (Santali) 

See: Indus Script hypertext पोळ pōḷa, 'zebu, bos indicus' signifies pōḷa ‘magnetite, ferrous-ferric oxide Fe3O4', पोलाद pōlāda, 'crucible steel cake' https://tinyurl.com/y9so6ubv

Slide 33. Early Harappan zebu figurine with incised spots from Harappa. Some of the Early Harappan zebu figurines were decorated. One example has incised oval spots. It is also stained a deep red, an extreme example of the types of stains often found on figurines that are usually found in trash and waste deposits. Approximate dimensions (W x H(L) x D): 1.8 x 4.6 x 3.5 cm. (Photograph by Richard H. Meadow) http://www.harappa.com/figurines/33.html

The oval spots are shaped like the copper ingots shown on this photograh of Maysar, c. 2200 BCE:

mūhā mẽṛhẽt = iron smelted by the Kolhes and formed into an equilateral lump a little pointed at each of four ends (Santali)

Another artifact which compares with the described shape of mūhā mẽṛhẽt 'steel ingot' is shown in the characteristic oval shape of a crucible steel buttton.

Decipherment of the Harappa figurine on Slide 33:

 पोळ [pōḷa], 'zebu' Rebus: magnetite, citizen.(See: http://bharatkalyan97.blogspot.in/2015/08/zebu-archaeometallurgy-legacy-of-india.html )
 mūhā mẽṛhẽt = iron smelted by the Kolhes and formed into an equilateral lump a little pointed at each of four ends (Santali)
 खोट (p. 212) [ khōṭa ] f A mass of metal (unwrought or of old metal melted down); an ingot or wedge. (Marathi)

The figurine signifies ingots of  पोळ [pōḷa], ‘magnetite’. This is a metalwork catalogue message in Indus Script Corpora.

The following proverb indicates the exalted status of the zebu, bos indicus which read rebus as  पोळ‘magnetite, ferrite ore’ is the life-sustaining wealth of the artisans:  ज्याची खावी पोळी त्याची वाजवावी टाळी. Of whom you eat the salt, him laud and exalt. टाळी (p. 196) ṭāḷī f (ताल S)  Beating the hands together.

There is a remarkable expression in Tamil which signifies the homonymous writing of similar sounding words as pictures in Indus Script. The expression is: போலியெழுத்து pōli-y-eḻuttu, n. < id +. 1. Syllable or letter resembling another in sound, as அய் for ஐ, அவ் for ஔ ஓர் எழுத்துக் குப் பிரதியாகஅவ்வொலியில் அமையும் எழுத்து. (நன். 124.) 2. Letter substituted for another different in sound, as in சாம்பர் for சாம்பல்; ஓர் எழுத்துக்குப் பிரதியாக வரும் எழுத்து. (நன்.)

போலியெழுத்து pōli-y-eḻuttu can thus be translated as rebus writing of Indus Script.

I suggest that since the majestic dewlap is the most characteristic feature of the zebu, the following etyma reinforce the identification of zebu,bos indicus as पोळ   pōḷa m A bull dedicated to the gods, marked with a trident and discus, and set at large: पोळी   pōḷī fig. A dewlap. पोळी पिकणें g. of s. To begin to fare sumptuously; to get into good living.

The oval-shaped incised spots on the zebu figurine signify crucible steel cakes and hence may be calledपोळ   pōḷa   पोळें   pōḷēṃ   पोळा   pōḷā  पोळी   pōḷī f. n C A cake-form or flat honeycomb;  fig. Any squeezed and compressed cakeform body or mass. पोळी (p. 305) pōḷī f A plain wheaten cake: also a cake composed of rice-flour boiled and rolled up with wheaten. 2 The cake-form portion of a honeycomb. 3 fig. Any squeezed and compressed cakeform body or mass. 4 Cotton steeped in a dye of lác, lodhra &38;c., flattened into the form of a cake, and dried;--forming afterwards, with water, a sort of red ink. 5 fig. A dewlap. पोळी पिकणें g. of s. To begin to fare sumptuously; to get into good living.

The smelting processes involved in making such crucible steel cakes are expressed by the following semantics of cognate words: अहारोळी   ahārōḷī f (अहार & पोळी) A cake baked on embers.पोळणें   pōḷaṇēṃ v i To catch, burn, singe; to be seared or scorched.  पोळा   pōḷā A kindled portion flying up from a burning mass, a flake.  पोळींव   pōḷīṃva p of पोळणें Burned, scorched, singed, seared. पोळभाज   pōḷabhāja f (पोळणें&38; भाजणें To burn &38;c.) In agriculture. A comprehensive term for the operations connected with the burning of the ground.

The cultural significance  attached to the crucible steel cake may be seen from the practice of offering a cake atop the Holi festival fire which is called : होळीची पोळी (p. 527) hōḷīcī pōḷī f The right (of villagers, esp. of the मुखत्यार पाटील) of first placing a पोळी (or cake) upon the pile which is kindled at the close of the festival of the होळी. 2 The cake so designated and applied.

दुपोडी पोळी (p. 237) dupōḍī pōḷī f (दु, पूड, पोळी) A पोळी or stuffed cake doubled up. Sign 294  is a doubling of a curve.dula 'two' rebus: dul 'metal casting' PLUS kuṭi 'curve;  kuṭika— 'bent' MBh. Rebus: kuṭila, katthīl = bronze (8 parts copper and 2 parts tin).
