This is an addendum to: Overflowing pot of m1656 pectoral and on Ibni Sharrum cylinder seal signifies Indus Script hypertext lokhaṇḍa 'metal tools, pots and pans, metalware' https://tinyurl.com/y6psctdw
Design principles of pictographic Indus Script.
1. A composite animal is created with a combination of hieroglyphs. For e.g., 'unicorn' is made up of: a. young bull; b. rings on neck; c. pannier' d. head of onager e. one crumpled, S-curved horn.

The overflowing pot atop the one-horned young bull is an Indus Script hypertext. The rebus reading in Meluhha of the overflowing pot is:
lokhaṇḍa 'metal tools, pots and pans, metalware' (Marathi) The expression is composed of two words: '(pot etc.) to overflow' and 'water'. The rebus readings are:
1. (B) {V} ``(pot, etc.) to ^overflow''. See `to be left over'. @B24310. #20851. Re(B) {V} ``(pot, etc.) to ^overflow''. See `to be left over'. (Munda ) Rebus: loh ‘copper’ (Hindi)
காண்டம்² kāṇṭam, n. < kāṇḍa. 1. Water; sacred water; நீர். துருத்திவா யதுக்கிய குங்குமக் காண்டமும் (கல்லா. 49, 16). Rebus: khāṇḍā ‘metal tools, pots and pans’ (Marathi).
Thus, the overflowing pot is a hypertext to signify metal tools, pots and pans of copper, made by .the young bull kār-kunda 'manager' who works as an artisan with the metallurgical competence of 'lapidary, goldsmith, turner' in mint.
Overflowing pot is an abiding metaphor on Ibni Sharrum cylinder seal and many other Ancient Near East artifacts.
2. 'unicorn' is normally shown in front of a standard device which is composed of hieroglyphs: a. lathe (top part) with a sharp gimlet; b. portable furnace (bottom part); c.dottedcircles on the bottom part; d. smoke emanates from the surface of the portable furnace; d. both parts held together with a flagstaff, for carrying on processions.
Mari procession shows a curious flagstaff to carry a 'unicorn' banner; the flagstaff is a cob of holcus sorghum, khoṇḍa as a semanic determinative of the 'unicorn' animal which is a young bull called khoṇḍa. This remarkable Mari frieze proves the underlying language of the hieroglyphs to be Meluhha, Indian sprachbund, 'language union'. The sprachbund is characterised by many variant phonetic forms.
3. Composite animal normalised as a sign is ligatured with a short tail with three prongs. kolom'three' rebus: kolimi 'smithy, forge' PLUS xoli'tail' rebus: kol'working in iron', kolhe 'smelter'
The Meluhha language signifiers are: kār kunda'adroit, clever, experienced, director, manager'. The 'unicorn' is a lapidary, turner, smelter, khār 'metalsmith' who creates kunda 'wealth', one of the nine treasures of Kubera.
Hieroglyph 'rim-of-jar' signifies rebus karaṇika 'scribe', karaṇī 'supercargo'.
The 'lid' is a ligature to Sign 342.
