An antique glaze is often used in conjunction with the crackle glaze to make the gold look older. Here you can see the results of using the antique glaze in some before and after pictures.
As you can see the effect is very pleasing to the eye. In the past I did use an oil based antique glaze, but I found problems as this type of glaze takes a long time to dry and can pick up dust very easily, I now use an acrylic based glaze, you simply rub in the glaze with a cotton pad making sure the glaze is worked into the cracks caused by the crackle glaze, you then simply wipe of the surplus glaze which leaves a thin coating all over the gilded area, and highlights the crackle.
I supply two different colour antique glazes which can used seperately or mixed together to achieve a wide range of different toned glazes.
Once again here are a couple of before and after pictures which demonstrate how the crackle glaze becomes highlighted after the application of the antique glaze.
When dry I suggest giving a final coat of lacquer in order to seal the whole piece.
Both these antique glazes and all other materials and equipment can be purchased from this site.
