Final answer:
Etching glass is known as Pattern Glass, which involves bonding enamel colored glass to a metal surface or plaque by firing. The option C is correct.
Step-by-step explanation:
Pattern Glass, also known as etching glass, stands out as a distinctive technique in glass artistry.
It involves utilizing enamel-colored glass in powdered form, which is fused to a metal surface or plaque through a firing process.
This intricate method employs melted glass or enamel to fill partitions created by metal wires attached to a metal base.
The result is a visually captivating and textured glass surface, often characterized by intricate patterns and vibrant colors.
A comparable technique, Cloisonné, shares similarities with Pattern Glass.
In Cloisonné, metal wires are also used to form partitions on a metal base, and the spaces between these partitions are filled with enamel.
Additionally, in Cloisonné, semi-precious stones may be inserted into small compartments for added ornamentation.
Hence, the option C is correct, etching glass is known as Pattern Glass.
