The oil contained in the seeds of the wild safflower (there known as polli) is in the first instance expressed by the cold process. [...] 8. Manipulation of Afridi Wax-cloth.--Before proceeing to discuss the chemical and commercial aspects of the polli oil and roghan it may perhaps be the preferable course to give a brief description of the manufacture of the goods generally designated Afridi wax-cloth. [...] The fading of the colours that sometimes takes place seems to be due to the use of inferior pigments such as white lead that consists mainly of barium sulphate and more especially to the presence of sulphur in the materials employed. [...] This is one of the many instances of the adatation of Indian industries to the requirements of the Europeans resident in this country and to the export trade to Europe. [...] Chemistry of polli oil and roghan.---From the study of the induPtry in Peshawar more especially the firm skin which the boiled oil formed and the circumstance that the roghan would not adhere to the moistened-tip of the finger I was led to suspect that one or other of these substances might prove of value as a wateproofing material.
