NOVELTY - The crucible (100) has an interior part (102) for producing an ingot (200) i.e. silicon ingot, that comprises a set of square-shaped blocks (202) i.e. grids, where perimeter (201) of the crucible comprises eight major sides including two sets of opposing longer sides (104) e.g. flat sides, of equal length, and two sets of shorter sides (106) of equal length. An exterior shape of a furnace matches with an interior shape i.e. round shape, of the furnace. The longer sides of the crucible alternate with the shorter sides, where the crucible is made of silica, quartz, graphite and silicon nitride.    USE - Crucible i.e. container for manufacturing an ingot e.g. multicrystalline ingot and silicon ingot utilized to produce a solar cell.    ADVANTAGE - The crucible utilizes four half-blocks for performing destructive and nondestructive measurement to improve quality and speed up throughput time of wafer manufacturing process, thus saving measurement time, time needed for block cleaning after conducting measurements and time needed for block cleaning before conducting block cutting post measurements, and hence achieving higher throughput of the ingot, while maintaining material quality of the ingot. The crucible measures axial resistivity profiles on the blocks, thus providing reliable information about growth front of the ingot. The crucible maps recombination service life of the blocks in high-carbon feedstock or at poor carbon control of a casting tool so as to measure the service life of the ingot as a function of distance from walls of the crucible walls and provide guidance on potential measures to be initiated for material quality improvement in wafer level. The crucible performs infrared scanning of silicon carbide particles so as to provide orientation information about the ingot. The crucible is coated with a material that prevents the material of the ingot from sticking to the crucible, thus allowing for easy removal of solid from the walls of the crucible. The crucible utilizes available furnace space in an efficient manner, thus avoiding purchase of a larger furnace and producing more blocks in a single batch of blocks.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for utilizing capacity of a furnace.
