"In the last few years, it has been a major development in the field of chemical analysis especially with instrumental technique in the exploration, mining and metallurgical industries. This development provided the fulfillment of chemical analysis criterion, such as accuracy, precision, sensitivity even the speed of analysis. The meaningful analytical measurement are achievable when both reference sample and reference methods have been standardized. Chemical analysis in the mining industry is continually making measurement comparisons between unknown and references' samples. One of the research activities of MTRDC in 1994/1995 is to prepare the reference standard kaolin sample for chemical analysis in the laboratories. Two samples have been prepared namely CLK and BLK and their concentration of SiO2. Al2O3, Fe2O3, TiO2, MgO, K2O, and LOI which have been recommended. "

"ABSTRAKThis paper presents short notes and comment on the problems of a scientist in writing and publishing a book in his/her field of majoirty or interest, either in exact (mathematical, statistical, and technical) sciences or social-economics, supported by my observation. Based on my observation and experiences, a scientist has lack of interest in writing a text or reference book, because of (i). The problem with the publisher, (ii) the capability and willingness of the scientist to present special and unique materials compare to other books, and (iii) lack of willingness of other scientists in using the book at least for a reference of their lecturers."
