This is a reproduction of a charge of blasting pellets, used in the early 1900’s before dynamite became more popular. Each stick is lightly waxed, as were the originals. Saltpetre is not misspelled, that is the British spelling of it.
Non functional, and cannot be made to function, for collectors, historical purposes only. Great for a historic mining display.
