How Do You Use Powdered Enamel?

Published in Enameling Techniques 2 mins read

Powdered enamel is primarily used in enameling, a technique where you fuse glass particles to metal through high-temperature firing. You can use powdered enamel in a few different ways, mainly by applying it dry or wet.

Methods of Applying Powdered Enamel

Here's a breakdown of the common methods:

  • Dry Sifting: This involves using a sieve or sifter to sprinkle dry enamel powder evenly onto a prepared metal surface.

    • The metal surface needs to be clean and often pre-treated with an adhesive to help the enamel stick.
    • Multiple layers of enamel can be applied this way, firing each layer before applying the next.

  • Wet Packing: This technique involves mixing enamel powder with water or a binding agent to create a paste or slurry.

    • ChamplevĂ©: You fill recessed areas in the metal with the wet enamel.
    • CloisonnĂ©: You fill compartments created by wire (cloisons) soldered to the metal surface with the wet enamel.
    • Wet packing is useful for detailed designs and filling specific areas.

Steps for Using Powdered Enamel (General Guide)

  1. Preparation:

    • Clean the Metal: Remove any dirt, oil, or oxidation from the metal surface.
    • Prepare the Enamel: Depending on the method, either keep the enamel powder dry or mix it with water or a binding agent.

  2. Application:

    • Dry Sifting: Sift the dry enamel evenly over the metal.
    • Wet Packing: Apply the wet enamel to the desired areas using a spatula, brush, or other suitable tool.

  3. Firing:

    • Place the enameled piece in a kiln and fire at the appropriate temperature for the specific enamel being used. Follow the manufacturer's instructions.
    • Firing fuses the enamel particles together and bonds them to the metal.

  4. Finishing:

    • Allow the piece to cool slowly.
    • Inspect for any imperfections and re-fire if necessary.
    • Grind or polish the surface to achieve the desired finish.

Enameling Both Sides

You can enamel both sides of a metal piece. Typically, one side is enameled first, fired, and then the other side is enameled and fired. This helps prevent warping or distortion of the metal during the firing process.
