Learn More

Oceanside System 96 is a COE96 art glass system manufactured by Oceanside Glass & Tile in Oceanside, California, USA. This glass follows in the lineage of the former Spectrum Glass (COE96) and features a wide product lineup suitable for both fusing and stained glass. Its annealing point (Tg) is 510°C, and its softening point (Ts) is 696°C; its viscosity curve is shifted toward higher temperatures compared to the Bullseye COE90 series.

COE96 falls between COE90 (Bullseye) and COE104 (Effetre Murano); because it has a different coefficient of thermal expansion than COE90-series glass, it cannot be mixed with it. Under the unified “System 96” standard, a full range of colored glass, clear glass, and frit is available; the recommended temperatures for specific techniques, such as pot melt (810°C), differ slightly from those of the Bullseye series. In Japan, these materials are primarily available through specialty stores, and there are fewer TechNotes available compared to those for Bullseye.

Physical Data

Coefficient of thermal expansion (COE): 96 × 10⁻⁷/°C. Slow-cooling point: 510°C; bubble squeeze: 621°C; full fusing: 788–815°C.

Product Features

A COE96 series for fusing and stained glass that combines the lineages of the former Spectrum Glass and Uroboros. Positioned between COE90 (Bullseye) and COE104 (Effetre Murano), it offers a wide selection of colored and textured glass sheets designed for fusing.

Country of Origin

United States (California). Manufactured by Oceanside Glass & Tile (OGT).

Related Concepts

By comparing Bullseye COE90 (bullseye-coe90), Effetre Murano (effetre-murano), COE (coe), and the VFT equation (vft-equation), we can systematically understand the coefficients of thermal expansion of each glass system and their impact on firing design.
