This page relates ‘Details regarding the Manufacture of Bricks (Ishtaka)� of the study dealing with Mayamata—an ancient Indian architectural treatise dealing with building construction (bhavana-nirmana). It forms part of “Vastuvidya�: a stream of Sanskrit technical literature encompassing village and town planning, temple architecture and other aspects like site selection, orientation, and structural arrangements aimed at promoting harmony and prosperity.

Part 7.5.7 - Details regarding the Manufacture of Bricks (Iṣṭakā)
[Note: This article is part of the series: 岹ṇa-ⲹ-parigraha-Բ (Measurement of the pillars and regulation of the acquisition of materials)]
According to the Mayamata, there are four types of soil in the earth:
Regarding on ĪśԲśܱܰ貹پ also records the same information.
It is stated that:
첹ṇ� ṇḍ ca ṇ� ca vigarhitā |
caturthī 峾phullā tu karmayogā mṛdiṣyate || (ĪśԲśܱܰ貹پ, . 33.36)�첹ṇ� (smooth), ṇḍ (off-white), and ṇ� (salty) soils are considered unsuitable for the construction. The fourth type, 峾phullā (red-swollen), is deemed appropriate for work."][1]
Maya recommends using red-swollen soil for making bricks (ṣṭ). Soil of this category should be devoid of gravel, pebbles, roots, and bones. It should be blended with white sand until the mixture achieves a smooth and pleasant texture to touch.
Firstly, the clay soil should be placed in a pit filled with water. After some time, once the soil is fully soaked, it should be continuously crushed by foot. Then, this mixture should be soaked in the extracts of ṣīr, kadamba, amra, abhaya, ṣa, and mixed with water from ٰ (amla, haritakī, and bahera). Afterward, the mixture should be crushed thirty times.
The width of the bricks should be measured in units of four, five, six, or eight digits, and the length should be twice of the width. The thickness of the bricks should be half, one-fourth, or one-third of their width. Bricks (ṣṭ) can be dried in sunlight or fired in a kiln. After a few months, the sthapati wets these bricks with water. They should be dried again before being used in building construction. It should be noted that the same method is followed even today.
Բ (chap 257), ṛhٲṃh (chap 57), վś첹-ś, վṣṇܻdzٳٲ-ܰṇa (chap 92) etc. also illustrate the choice of materials for building construction. In the texts ṛhٲṃh and վṣṇܻdzٳٲ-ܰṇa the concept of vajralepana (similar to cement) is discussed. The vajralepana can be made following two different methods. Here, the first method is to be discusses depending on վṣṇܻdzٳٲ-ܰṇa.
It is stated that�
ata� para� pravakṣyāmi vajralepavidhi� tava |
bilavakāṃśca kapitthāṃśca āmrān saṃhṛtya yatnata� ||
śālmalīnā� tathā ṣp� sallakībījameba ca |
dhanvanaśca(dhanuścāpi) tathā 첹첹� � ca manujeśvara || ..... (վṣṇܻdzٳٲ-ܰṇa, 92.1-2)[ �Bilvaka, Kapittha, Ā as well as the flower of Śī, the seed of ī, the skin of Dhanvana and Vaca should be taken in equal parts and mixed up in water eight times in quantity. The whole mixture should be boiled till it reduces to one-eight. Then the following things should be put into it; the վԲ of ī, the Guggula of Bakula, ٲ첹, Bilva, Kunduru, Sarja and ٲī. When it (this mixture) is heated properly, it is called Vajralepa.”][2]
Second method to process the Vajralepana is to be discussed here depending on ṛhٲṃh. The text mentions that:
ṣākܲԻܱܰܲܲܲṛhū첹辱ٳٳԾ |
岵پԻܰ첹岹Բܰ첹ñᾱṣṭ� ||
sarjjarasarasāmakāni ceti 첹첹� kṛto dvitīyo’ya� |(ṛhٲṃh 57.5-6)
“There is a second glue of excellent qualities made of the sediments, as explained before, of lac, Kunduru, Guggulu, jouse smoke, wood-apple, Bilwakernel, fruits of Naga, Neem, Tinduka and Madana, madder, Sarjarasa, Raktabola and Amalaka.”][3]
