Decoart Glass Stain Black Leading Outliner
Apply Glass Stain to surface with bottle's writer tip or with a brush. Dry flat for 24 hours. Use for decorative purposes only. Not for direct contact with food. Hand wash painted items, and do not soak. Cleans up with soap and water while wet.
Hold the bottle's tip slightly above the surface as you work for best results and smoother lines. Use a consistent pressure to make a thick line to hold in the Glass Stain.
