「GLASS」は FontVibe AI で作成したガラスの文字エフェクトです。光を屈折させる透明な光学ガラスの大文字。明るい縁のハイライトとコースティクスが、緑青のオーロラの空の下、暗い面に映り込みます。

Create a finished square typographic artwork featuring exactly one word: “GLASS”. Center the word as the clear, unmistakable focal point, large and carefully spaced, occupying about 70% of the canvas width. Form every uppercase letter as a sculpted, liquid-pulled piece of high-clarity transparent optical glass: bold, elegant display proportions, smooth rounded curves and terminals, consistent stroke weight, precise cut facets along the glass edges. Keep the glass untinted and transparent, with the softly illuminated lavender-blue background visibly refracting through the letter bodies. Bright, fine specular lines trace the transitions in glass thickness; gentle internal refractions and subtle rainbow dispersion appear only at the sharpest edge angles. Give the edges a slight frosted diffusion so they feel soft rather than razor-crisp, while preserving a clear glass body. Beneath each letter, cast soft, luminous caustic patterns onto a pale glossy surface, with overlapping pools of refracted light. Use gentle diffused backlighting and restrained highlights, no harsh shadows and no dark dramatic areas. Set a serene lavender-blue gradient background, lighter behind the word and softly deepening toward the outer corners. The result is minimal but tactile: an optical-glass lettering study with liquid softness, depth, and legibility. No extra words, symbols, props, borders, or decorative graphics.
