Black blasting powder for stone-cutting
The black blasting powder VESUVIT® TN is a mixture of potassium nitrate, sulphur, and charcoal. It is a powdery granular substance of grey-black colour with a semi-glossy surface (graphite). VESUVIT® TN is used for easy blasting of unbroken pieces of high-grade rocks (block mining) or for blasting works in easily blasted rocks. VESUVIT® TN is not water resistant, and can be used only in a dry environment under the conditions listed in its instruction manual. It is charged into the blastholes or grooves using cartridges in paper packing. An electric detonator, a safety fuse, or an igniter with an initiation ability such as the standard igniting detonator No. 8 can be used for ignition.
