1. Firing Lyddite shells, or using trench mortars, was tried. 2. The British started replacing lyddite with TNT in 1907. 3. Lyddite presented a major safety problem because it reacted dangerously with metal bases.4. Hence it was not simply a case of switching existing filling machinery from Lyddite to Amatol. 5. Its original shell was Lyddite explosive. 6. Shell filling began on 11 November 1916, with both Lyddite and Amatol explosives being used in production. 7. After surviving gunfire from in which shells filled with lyddite were tested, she was towed back to Portsmouth. 8. Experiments with high explosives carried out on the shingle wastes around 1888 led to the invention of the explosive Lyddite . 9. They were replaced by " common lyddite " shells in the late 1890s but some stocks remained as late as 1914. 10. Proper detonation of a lyddite shell would show black to grey smoke, or white from the steam of a water detonation.
