Brush on the brilliance! Pebeo's Vitrail Glitter Medium brings luminous sparkling effects to painted surfaces without losing transparency. Mix Sparkling Medium into paint and apply it directly to glossy surfaces like glass, Plexiglas, and acetate to add depth, sparkle, and brilliance. Apply it directly to surfaces such as metal to obtain a reflective, glittery finish, or wood and canvas for a rich, glossy, transparent finish. Or mix it with Vitrail color and Vitrail Matte Medium to create frosted effects.
