sentences:  The "Tovex" (that replaced nitroglycerin-based dynamite) had evolved into a cap-sensitive product.Even though it bore the same name as the earlier "Tovex," it was quite different from the precursors, which could only be initiated in large diameters (5 inches) with a one pound TNT booster.The new Tovex of the mid-to-late 1970s could be detonated in (critical) diameters much smaller than 5-inches by utilizing DuPont's Detaflex, thus making the new Tovex a realistic replacement for dynamite.
