Black Powder
VESUVIT® TN
The VESUVIT® TN black powder is a mixture of potassium nitrate, sulphur
and charcoal. This black powder is bulk granulated material of a gray-black
colour with a semiglossy surface (graphite).
VESUVIT® TN is used for careful disintegration of unbroken pieces of noble
rocks (block mining) or during blasting works in easily disintegrable rocks.
VESUVIT® TN does not resist water and may only be used in a safety fuse
under the conditions specified in the corresponding user manual. It is
charged into blast holes or joints. An electric detonator, safety fuse or
igniter with initiation ability such as standard ignition detonator No. 8 can
be used for initiation.
VESUVIT® THH
The VESUVIT® THH black powder is a mixture of potassium nitrate, sulphur
and charcoal. This black powder is bulk granulated material of a gray-black colour with semiglossy or matte surface. VESUVIT® THH is used for blasting works, as a primer mixer or rocket fuel.
VESUVIT® THH does not resist water and may only be used in a dry
environment under the conditions specified in the corresponding user
manual. It is charged into blast holes or joints. An electric detonator, fire
cord or igniter with initiation ability such as standard ignition detonator
No. 8 can be used for initiation.
