ILLUCKAI 12 Sheets 90 COE Fusible Glass 6 x 4 in - Rainbow Value Pack

Our review of the ILLUCKAI 12 Sheets 90 COE fusible glass pack finds it best suited to hobbyists and small-batch jewelry makers who need a modest, colorful supply of compatible fusible glass. The single biggest reason to buy is the variety and ready-to-use sheet size: twelve 6 x 4 in sheets in opaque rainbow colors that eliminate early trimming for many small projects and ensure compatibility with COE 90 firing schedules when paired with like glass. This reviewer found the pack useful for pendants, small panels and sun catchers where consistent fusibility and color variety matter.

Key Features

• Value Pack: Twelve 6 x 4 in sheets provide an economical set of pieces to start multiple small projects without frequent reordering.
• COE 90 Compatibility: The sheets are specified for COE 90 fusing, which reduces the risk of devitrification and stress when matched with other COE 90 glass.
• Opaque Rainbow Colors: A range of vibrant, opaque colors gives visual variety for jewelry, sun catchers and mosaic elements without the need for additional paints or stains.
• Craft Versatility: The sheet size and material make these suitable for beads, small fused panels, lampshade accents and stained glass craft pieces.
• Precut Convenience: Standard 6 x 4 in sheets save time on cutting and layout for many small fused glass designs.

Who It's For

The pack is aimed at glass fusing hobbyists, beaders and makers who regularly fuse COE 90 glass and want a sampler of colors in usable sheet sizes for pendants, small tiles and suncatchers. It is also well suited to classroom settings or craft groups that need an easy, ready-to-distribute quantity of fusible glass.

Those who should look elsewhere include artists who require large-format sheets, precise transparency control, or who primarily fuse with a different COE such as 96; the product is explicitly intended for COE 90 compatibility and warns against mixing with other glass systems.

Pros & Cons
