Lusters are liquid.
You can use them on porcelain and glass objects and they create metallic and shimmering reflects that change color with light.
Brushes used with lusters should be correctly cleaned and be kept for exclusive use with Lusters.
Lusters can be unpredictable when firing, but very fun to try out!
