This product is water based and can dry up, so always keep the container tightly capped. If it is dries up, add an appropriate amount of water to recover its original state.

If you need to build the Gold layers more than 0.5mm in thickness, fire the piece first, and then build another layer on top of the fired gold area. Repeat until reaching your desired thickness.

The surface of the fired area where Gold Paste was applied will be matte in color due to crystallization, but a luster can be obtained by polishing.

Do not polish gold overlaid area on the glazed surface too hard, as it may chip off with the glazed surface. Polishing the area with light gliding stroke is enough bring out the shine. If the Gold area chips off during polishing, it is possible to attach it with Art Clay Silver Overlay Silver Paste*. *Requires second firing to attach.

To dilute the paste, take out the necessary amount and place in in a separate container. Then, add necessary amount of water or medim depending on your desired finished gold color.
*Recommended ratio for diluting the Gold Paste with the medium is 3 (Gold Paste) : 1 (Medium).

Preparation

Clean the surface of the porcelain , glass or ceramic with a alcohol, or soap and water to remove dust or oil. They may disturb Gold Paste attaching on the surface.
*Prepare a paintbrush specifically for use of the Gold Paint.

You may remove the piece when the temperature reaches 100℃/212°F, or cool naturally to room temperature.

Option3: Application on a glass* surface

This firing is for glass COE 90. Please do test fire if you use different COE glass.

Kiln firing

Place the piece in a cold kiln and fire to 800℃/1472°F.
