Powder and shells are ideal for retouching leaf gilding and the gilding of carved or difficult to reach surfaces. Available in two carats, powders must always be first mixed with specific binding agents prior to application with a fine, soft bristle brush. Available only in 23 3/4 carats, shells are ready-to-use mixtures of genuine gold and gum arabic. In this way they can be applied on the surface to be decorated using a fine brush moistened with water, like a watercolour.
To apply with a brush, powders and shells are the best formats for any retouching and for carved or highly irregular surfaces.
