A terracotta cake is a piṇḍa पिण्ड [p=625,2] m. (rarely n.) any round or roundish mass or heap , a ball , globe , knob , button , clod , lump , piece (cf. अयः-. , मांस- &c ) RV. (only i , 162 , 19 and here applied to lumps of flesh) TS. S3Br.&c; n. ( L. ) iron; steel (Monier-Williams. Samskritam). What archaeometallurgical functions were served by the terracotta cakes offered as piṇḍa पिण्ड in fire-altars? One possibility is that the terracotta cakes (of circular and triangular shapes) served the functions of piṇḍikaa which is a support base for the Sivalinga which is a divine impeller of the cosmic dance of transmutation occurring in a fire-altar.   A skambha linking heaven and earth, a fiery pillar of light. The following three ricas of Rigveda also refer to and explain the metaphor of skambha as a prop which upholds heaven and earth; RV 9.89.6 places it in the context of purification of Soma, reinforcing the possibility that the Skambha signified the impeller of the purification process of yajna -- a process which is replicated in the purification of metals in a smelter/funace/fire-altar:10.111.05 Indra, the counterpart of heaven and earth, is cognizant of all sacrifices, he is the slayer of S'us.n.a; he spread out the spacious heaven with the sun (to light it up); best of proppers, he propped up (the heaven) with a prop. [Propped up the heaven with a prop: Satyata_ta_ = that which is stretched out by the true ones, the gods; or, ta_ti as a suffix, that which is true, i.e., heaven]. 9.074.02 The supporter of heaven, the prop (of the earth), the Soma-juice who, widely spreading, filling (the vessels), flows in all directions-- may he unite the two great worlds by his own strength; he has upheld them combined; (may he) the sage (bestow) food upon (his worshippers). [The prop of the earth: cf. RV. 9.089.06; may he unite: yaks.at = sam.yojayatu; a_vr.ta = by its own unaided strength].9.089.06 The prop of heaven, the support of earth-- all beings (are) in his hands; may (Soma) the fountain (of desires) be possessed of horses for you (his) adorer; the filament of the sweet-flavoured (Soma) is purified for (the sake of winning) strength.  http://bharatkalyan97.blogspot.in/2015/12/archaeometallurgy-of-cementation.html   

Linga with One Face of Shiva (Ekamukhalinga), Mon–Dvaravati period, 7th–early 8th century. Thailand (Phetchabun Province, Si Thep) Stone; H. 55 1/8 in.

Octagonal form of ViSNubhAga and the occurrence of pancamukhalinga is consistent with the tradition of pancaloha 'five dhAtu or five mineral alloy' images as utsavaberas.

Ekamukhalinga from JaiyA, National Museum, Bangkok. The shape is as described in Satapatha Brahmana, 

quadrangular base, octagonal middle, caSAla at the top (made of wheat straw paste).

Ekamukhalinga from Vat Sak Sampou

“The JaiyA ekamukhalinga is divided into three parts in accordance with the prescriptions in the Siva Agamas. The base, BrahmabhAga, is cubic in form and is 47.8 cms. High. The middle section, the ViSNubhAga, is octagonal in shape and is approximately 43 cm. High. The topmost section, the RudrabhAga, is cylindrical and is approximately 51 cms high, while the superimposed face measures 29.5 cms from the bottom of the chin to the top of the jaTA. The two lower sections of the linga would not normally be visible, since they would be enclosed in the pedestal (pIThikA)...One of the singular features of these pre-Angkorian mukhalingas is the fusing of the jaTA with the filet on the gland of the RudrabhAga (fig.2)...There is, however, an ekamukhalinga from Vat Sak Sampou (fig. 3) which displays a coiffure which is very muh like that worn on the JaiyA linga.” (O'Connor, SJ, 1961, An ekamukhalinga from Peninsular Siam,  The Journal of the Siam Society. The Siam Society. pp. 43-49).
