The section has successfully carried out research and development in the areas of tableware production, low tension electrical bobbin insulators and fire clay crucible production. This has enabled the section to produce table ware and fire clay crucibles as follows:
PRODUCTION OF HIGH QUALITY TABLE WARE CERAMIC PRODUCTS AND FIRE CLAY CRUCIBLES
-Tableware products
Since 1997 the industrial Minerals application section has been producing high quality ceramic ware products on a small scale level. The products are available for sale at the Centre's premises and at distribution points at slip way, and at the Centre's display room at Kunduchi.
-Fire Clay crucibles
The section has started production of good quality fire clay crucibles which are currently used internally in the Centre's gold assay activities using its roller head machine. These products will eventually be available for other users like the minerals explorations companies operating in Tanzania and even for member States laboratories.
