Copper gold powder is a versatile material with numerous applications, especially in creating imitation metal finishes. One popular use is in the production of fake brass items. Below, we’ll walk you through a simple method for making imitation brass using traditional techniques.
**Main Tools and Materials Used:**
Brush, row pen, emery cloth, copper powder, nitro varnish, iron oxide yellow, shellac varnish, green paint, blue paint, carbon black, light wax, golden block, oil paint, alcohol varnish, gasoline, paint pot, chrome green.
**Step-by-Step Process for Imitation Brass Production:**
1. **Preparation:** Start by cleaning the craft item thoroughly to remove any dust or debris. Then, sand down any imperfections or seams until the surface is smooth. Afterward, apply a thin layer of shellac varnish and let it dry completely. Apply a second coat and allow it to dry again.
2. **Base Color Application:** Once the base is dry, use a wool pen to draw patterns or details on the surface. Mix shellac varnish with iron oxide yellow to create a warm base color. Apply this mixture evenly over the surface and let it dry.
3. **Gold Powder Painting:** After the base color has dried, apply gold powder paint in two layers. The first layer should be applied and allowed to dry before applying the second. This will give the item a rich, realistic brass finish.
**Gold Powder Paint Formula:**
- 1 part copper powder
- 2 parts nitro varnish
- 3 parts banana water (a common solvent used in painting)
**Preparation Method:**
Mix the banana water with copper powder first, then stir until fully dissolved. Add the nitro varnish and mix thoroughly. This mixture should be used immediately, as leaving it for too long may cause the gold luster to dull.
**Shellac Varnish Formula:**
- 100–150 grams of insect film (a natural resin)
- 500 ml of alcohol
**Preparation Method:**
Dissolve the insect film in alcohol first, then add iron oxide yellow to achieve the desired color. Do not filter the mixture; it can be used directly.
It’s important to note that copper gold powder comes in different varieties, such as red-gold, blue-gold, and red-blue gold. Depending on your project, choose the appropriate type of glossy copper powder for the best results.
