Further the \*Kūpipakva rasāyanas\* (mercurial compounds of red sulphide type) prepared through \*Bālukā Yantra\* system of heating in \*kāca kūpi\* (glass bottle prepared specifically) could be prepared only after the development of \*Mūrcchanā\* process. Besides a few apparatuses and a specific heating system/method is also found referred to in \*Rasendra Cintamani\* (12th century A.D). The \*Rasa Sindura\*, \*Makaradhvaja\* and \*Rasa Karpūra\* are some of the examples of \*Kūpipakva rasāyanas\* and deserve mention in this context. - [Previous: v1.c18.5](https://indike.org/pramana/ins.science.bag-1997.v1.c18.5) - [Next: v1.c18.7](https://indike.org/pramana/ins.science.bag-1997.v1.c18.7) - [Up: v1.c18](https://indike.org/pramana/ins.science.bag-1997.v1.c18) ## Cites (2) - [Cakradatta (Cikitsāsaṅgraha)](https://indike.org/pramana/in.med.sangraha.gauda.cakradatta) — Cakrapāṇidatta, Sanskrit - [Rasendracintāmaṇi](https://indike.org/pramana/in.med.rasa.samuccaya.pramukha.rasendracintamani) — Ḍhuṇḍhukanātha, Sanskrit --- Source: [https://indike.org/pramana/ins.science.bag-1997.v1.c18.6](https://indike.org/pramana/ins.science.bag-1997.v1.c18.6) · Pramāṇa
