Shaping Phase
You can easily apply the overlay paste with a brush or carefully in thin layers onto the desired surface. It is recommended to apply the paste in multiple layers to ensure proper coverage and give your workpiece a smooth finish. Start with a thin layer diluted with distilled water and allow it to dry thoroughly before applying the next layer.
Drying Phase
The Art Clay Silver Overlay Paste dries naturally, so be mindful of this while working. Ensure your piece is completely dry before applying additional layers. If the paste in the pot has dried out, add a few drops of distilled water and stir it well with a toothpick or other suitable tool. Let the moisture sit for a while before stirring to achieve the right consistency.
Once the paste is completely dry, the piece will have the hardness of plaster, allowing you to continue working, repairing, or joining parts.
Shrinkage and Firing
The overlay paste shrinks by about 9% during firing. This is important to consider, especially when creating detailed designs. Make sure your piece is completely dry, particularly after applying extra layers of paste, to prevent it from distorting during the firing process. The ideal firing temperature is between 800°C and 900°C. The duration of the firing will depend on the heat source used.
Finishing Phase
After firing, the overlay paste will have a crystalline structure and will appear white. For finishing, you can use a polishing brush for a matte finish, or continue polishing with polishing sponges, an agate pen, polishing needle, or sanding discs with a Dremel for a glossy result.
