Materials & Gems

Material names (steel, wood, glass, copper, silver, iron, marble, leather) are practical Morse vocabulary in trades, crafts, and engineering contexts. Telegraph wires themselves were originally drawn copper, and the resonance of Morse code is partly the sound of dot-dash impulses moving through copper conductors. Material words in Morse appear in craftsman jewelry, blacksmith signage, and engineering anniversary plaques. Most run 4 to 7 letters, transmitting in 2 to 4 seconds at standard speed.
