Care & Information – Murrini (COE 96)

What Are Murrini

Murrini (singular: murrina) are patterns created inside glass cane.
When the cane is sliced, each cross-section reveals the design — from simple shapes to more detailed motifs such as flowers, stars, or abstract forms.

This technique has been used for thousands of years and was later refined by Venetian glassmakers on the island of Murano.

How Our Murrini Are Made

At Fabio di Vetro, murrini are created using a vitrigraph process.

Glass is carefully arranged inside a vessel and heated in a kiln until molten.
It is then pulled into glass cane, where the internal design is formed by the original arrangement.

When sliced, each section reveals a unique pattern.

Handmade Character

All murrini are handmade and individually cut.

Variations in:

  • Pattern

  • Size

  • Detail

are a natural part of the process and not defects.

No two pieces are ever exactly the same, and this individuality is part of their character.

Compatibility (COE 96)

All murrini are made using COE 96 compatible glass.

They are suitable for:

  • Glass fusing

  • Jewellery making

  • Decorative glass work

Important:
Only use with other COE 96 compatible glass.

Glass with different COE values expands and contracts at different rates during heating and cooling.
For example, COE 90 and COE 96 glass are not compatible and should not be fused together, as this can cause stress, cracking, or breakage.

Fusing Guidelines

Tack Fuse

  • Approx. 700–760°C

  • Murrini retain more shape and texture

  • Patterns remain more defined

Full Fuse

  • Approx. 780–805°C

  • Glass flows and flattens

  • Patterns soften and spread

Final results will vary depending on kiln, firing schedule, and setup.

Firing Notes

A firing schedule controls:

  • Temperature

  • Speed of heating

  • Holding time

Every kiln behaves differently, so results may vary.

Testing small samples before final pieces is always recommended.

Important Notes on Results

During firing:

  • Patterns may expand

  • Fine details may soften

  • Spacing will affect the final look

This is part of the creative process when working with murrini.

Handling & Storage

  • Store in a dry, stable environment

  • Handle with care to avoid chipping

  • Keep pieces separated where possible

Final Note

Murrini are not mass-produced elements.

Each slice is a small piece of handcrafted glass, carrying slight variations that make every finished piece unique.

This individuality is at the heart of fused glass work.
