marver

This term is highly specialized jargon used almost exclusively within the craft of glassblowing. It refers to both the physical tool—a heavy, heat-resistant table or slab—and the specific action of manipulating molten glass upon that surface. The process is critical for controlling the temperature of the glass and shaping it before further blowing or sculpting.

Because it is a technical term, it is rarely encountered in general conversation and is typically used in a professional studio or artistic context. When used as a verb, it describes a precise physical motion of rolling the glass to achieve uniformity or specific patterns.
