Originating in Japan, *yakisugi* is a traditional method of wood preservation that involves charring the surface of cedar boards to make them resistant to fire, rot, and insects. The process begins by binding three boards into a triangular chimney, lighting the interior, and allowing the flames to rapidly carbonize the wood. This superficial burning creates a thick layer of carbonized cellulose, which acts as a natural barrier. Ultimately, the charred layer protects the underlying timber from environmental degradation, ensuring its longevity for decades.
The writer wants to revise the underlined portion of the sentence below to provide the most specific, concrete visual details that illustrate the physical appearance of the carbonized surface:
"This superficial burning creates a thick layer of carbonized cellulose, which acts as a natural barrier."
Which choice best accomplishes this goal?
- Aa thick layer of carbonized cellulose, which acts as a natural barrier.
- Ba layer of carbonized cellulose; which creates a dark, flaky coating that acts as a natural barrier.
- a silvery-black, cracked texture resembling alligator hide that repels moisture and prevents insect infestations.Cevap
- Da protective outer layer, this carbonized coating blocked moisture and decay.
