The 2D stain has moderate viscosity and can be evenly applied to any ceramic restoration surface.Colouring liquid 1 is used for all 2D staining pastes and serves as a diluent. If a thin layer of paste needs to be applied, it can be used to reduce the viscosity of the paste.When the Glaze-F paste is too thick, you can use the colouring liquid to reduce the viscosity of the paste. The glaze F will also have a glazing effect.Before using, stir the paste thoroughly with a glass rod to achieve good consistency before adding and adjusting. Too much use of the colouring liquid 1 may affect the operation.Do not add the colouring liquid directly into the paste bottle and stir it. It is recommended to mix it with the paste on the palette. Be sure that the paste has been mixed thoroughly to the correct consistency.
