Underglaze Decoration Applying Underglaze Colors

Applying underglaze colors is like painting on a canvas, except your canvas is your clay piece. Underglazes are fantastic because they allow you to add vibrant colors, intricate designs, and personal flair to your pottery. Whether it’s a simple mug or an elaborate vase, underglazes can really make your piece pop. Let’s walk through how to use underglazes and some tips to make your designs stand out.

Steps in Applying Underglaze Colors

  1. Choosing Your Underglazes: First up, pick your colors. Underglazes come in a wide range of colors, so have fun with it!
  2. Preparing Your Piece: Your clay piece should be bone dry or bisque-fired. Make sure it’s clean and free of dust.
  3. Planning Your Design: Before you start, it’s a good idea to sketch out your design. This can be directly on the piece with a pencil (lightly, so it burns off in the firing) or on paper.
  4. Applying the Underglaze: You can use brushes, sponges, or even your fingers to apply underglaze. Apply it evenly and watch for drips or uneven spots.
  5. Layering Colors: If you’re using multiple colors, wait for the first layer to dry before applying the next. This prevents the colors from blending unintentionally.
  6. Drying Before Firing: Once you’re done decorating, let the underglaze dry completely. This is crucial before the piece goes into the kiln.
  7. Firing: Bisque fire your piece following the specific temperature requirements of the underglazes you’ve used.

My Tips and Pointers

  • Test Colors First: Underglazes can change color during firing. It’s a good idea to test them on a small piece of clay first.
  • Thin Layers Work Best: Apply underglaze in thin layers. Thick layers can flake off during firing.
  • Be Creative with Tools: Experiment with different tools for applying underglaze. Brushes, sponges, and even stamps can create unique effects.
  • Smooth Application: For a smooth application, add a little water to your underglaze. This can make it easier to paint with.
  • Protecting Your Design: After underglazing, you can apply a clear glaze over the top. This seals in the underglaze and gives your piece a glossy finish.
  • Mind the Temperature: Always check the temperature range of your underglazes. Some colors can burn out or change at high temperatures.
  • Patience in Drying: Make sure the underglaze is thoroughly dry before firing to prevent any smudging or bubbling.

My Final Thoughts

Underglaze decoration is a wonderful way to express your creativity on your pottery pieces. It’s like the piece is telling a story through its colors and designs. Remember, every brush stroke adds character, and every color can convey a mood. So grab those underglazes and start decorating – your pottery masterpiece is just a few strokes away!
