Abstract
An improved thermite reaction containment vessel and method of using the same includes a filter assembly which serves to filter the gases evolving from the thermite reaction and reduce the amount of smoke, fume and the like by-products emitted. In one preferred embodiment the filter assembly comprises a primary filter and a secondary filter. An air gap may be provided between the primary and secondary filter so as to provide additional cooling of the gases before they enter the secondary filter. The invention further provides a remote electrical ignition system which is capable of igniting thermite reaction materials without the use of a starting material. The ignition system may include an ignition fuse having an aluminum core and an outer coating comprising palladium and ruthenium or hot wire.
