Vitrigraph Pattern Pots

Each set includes three pattern pots:

• 4.25 x 4.25 x 1.5
• 4.75 x 4.75 x 1.5

What are Pattern Pots?

When pulling murrine, the design can distort over time unless it’s built in sections—what we like to call blocks.

Since glass flows out like a funnel, it’s important to construct separate blocks that account for that movement, especially when working with intricate designs involving eyes or other fine details.

Think of it as designing a pattern bar that expands by approximately 25%. This method helps maintain a consistent design throughout a majority of the entire pull.

To begin, line the layout blocks with fiber paper, arrange your design, and tack fuse the pieces together. When you’re ready to load the vitrigraph pot, place the smallest block at the bottom, surround it with clear glass, and continue building from there.

Tip: When lining a metal pot, cut the fiber paper to size, join the seams, and place a piece of shelf paper behind the seam for extra protection. We do not recommend using Zyp with these molds as it can flake off and into your design.
