Lascaux Glazing Medium (Lasurmedium)

For painters who love slow, deliberate layering. Lascaux Glazing Medium extends open time so you can blend, soften edges, and build transitions without racing the clock. It increases transparency for true glazing—letting your underlayers glow through—without dulling the colour’s luminance.

This medium dries transparent with a matte finish, and once dry it’s lightfast and water-resistant—ideal for atmospheric veils, colour shifts, and luminous depth.

Key features: Transparent • Lightfast • Water-resistant • Matte finish • Extends open time • Boosts transparency without killing brightness
