Mining Railway T-Shirts

Description: Head down the shaft with this mining railway mine run design. It shows a narrow gauge ore cart train rolling through a dark mine tunnel, hauling heavy loads from deep underground. It’s a good fit for miners, prospectors, heritage rail fans, and anyone who loves gold rush history and the hard work of a mine run. A great gift for coal hopper fans, quarry train lovers, and anyone who knows the glow of a mine lamp lights the way through the tunnel.

Description: This scientific diagram shows three sticks of dynamite with a lit fuse, above the formula of nitroglycerin C₃H₅N₃O₉ and the pairing of nitroglycerin with kieselguhr that made it safer to handle, on a deep dark background. Patented in 1867, dynamite stabilized liquid nitroglycerin by absorbing it into kieselguhr, a porous diatomaceous earth. It transformed mining, tunneling and civil engineering. Made for chemists, chemistry teachers and anyone who loves the lab, it suits a laboratory, classroom, study or home office.
