What Will You Need?

To begin with, you will need to gather all the necessary materials and tools before starting your underglazing process. Here is a list of items that you will require:

• Spectrum Underglaze: This can be in powder or liquid form, depending on your preference.
• Ceramic Pieces: These can be already bisque-fired or greenware (unfired) pieces.
• Underglaze Brush or Sponge: You can use any brush size depending on the design and details you want to achieve.
• Water: To dilute the underglaze if needed.
• Wax Resist: Optional but helpful for creating designs with multiple layers of colors.
• Palette or Paint Tray: To mix and blend different colors.
• Sponges or Cloth: To clean up any excess underglaze or spills.

Once you have gathered all your materials, you can begin the underglazing process.

9 Easy Steps on How to Use Spectrum Underglaze

Step 1: Preparing Your Surface

The first and crucial step in using Spectrum underglaze is to ensure that your ceramic piece is adequately prepared. Begin by thoroughly cleaning the surface of your ceramic ware. If you are working with greenware, gently sponge down the surface to remove any dust or debris that could prevent the underglaze from adhering correctly. For bisque-fired pieces, a damp cloth can effectively remove residual kiln dust. Your ceramic piece must be clean, smooth, and dry before applying the underglaze, as any imperfections or moisture can affect the final finish and color intensity.

Additionally, you plan to use the wax resist technique. In that case, this is the stage to apply it, as it will create barriers for different colors, allowing for more intricate designs without bleeding into each other. Preparing the surface correctly will lay the foundation for a successful, beautiful underglaze piece.

Step 2: Selecting and Mixing Colors

Now that your ceramic piece is prepared, it’s time to select your underglaze colors. Spectrum underglazes are available in a wide range of hues, so take your time to choose colors that complement your design. If necessary, you can mix different colors to create unique shades.

To do this, pour a small amount of each desired color onto a palette or paint tray and blend them using a brush or spatula. It’s important to remember that the shades of wet underglaze may appear different once fired, so take a test tile to explore variations before committing them to your piece. Once you are satisfied with the selected colors and mixes, you can apply them to your ceramic surface with precision and creativity.

Step 3: Applying the Underglaze

With your colors ready, begin applying the underglaze to your ceramic piece. Depending on the desired effect and level of detail, you can use different tools such as brushes, sponges, or stencils. Use a fine-tipped brush to outline and define edges for more intricate designs.

Sponges are excellent for covering larger areas smoothly and evenly. If using stencils, ensure they are firmly secured to avoid any bleeding of colors. Start with a light coat to gauge how the underglaze adheres to the ceramic surface, and then build up additional layers to achieve the desired intensity. Allow each layer to dry before applying another to prevent lifting or smudging.

Step 4: Layering Colors

Once the initial layer of underglaze has dried, you can begin to layer additional colors to add depth and complexity to your design. This technique can create subtle color transitions and enhance the visual interest of your piece. Use a fine brush for precise applications, especially with intricate designs. If adding multiple colors, plan the sequence carefully, starting with lighter shades and progressively using darker tones to build contrast.

Be mindful of the drying time between layers, as applying a new layer too soon may result in smudging or uneven coverage. Experiment with blending techniques on a test tile first to ensure your desired effect is achievable before applying it to your main piece. The layering process is an opportunity to showcase your creativity and deepen the visual texture of your ceramic artwork.

Step 5: Adding Details and Patterns

As your layers of underglaze build up to create dynamic tones and shades, the next step involves adding finer details and patterns to elevate your piece. Use precision tools such as detail brushes, styluses, or fine-pointed pens designed for ceramics to outline intricate patterns, such as florals, geometric shapes, or abstract designs.

The key to success in this stage is a steady hand and a clear vision of the desired outcome. For added interest, consider using techniques such as sgraffito, where gentle scraping reveals contrasting layers beneath the surface, or resist methods for areas of high contrast. Patience and meticulous attention to detail during this step will enhance the intricacy and craftsmanship of your finished ceramic artwork.

Step 6: Drying and Finishing Touches

Once you have completed adding all desired details and patterns to your ceramic piece, it’s imperative to let the underglaze dry thoroughly. Drying is crucial as it ensures all layered colors and intricate designs settle properly without blending or smudging. The drying time can vary depending on the humidity and temperature of your workspace, so allow ample time, mainly if you have applied multiple layers.

After the piece is arid, inspect it for any final touch-ups. This is the last chance to modify details or add underglaze before the firing process. Ensure all final adjustments are completed with care to maintain the integrity of the design. Once you’re satisfied with the finished look, prepare the piece for the following stages, typically glazing and firing, to solidify your artistic creation and bring out the vibrant colors of the underglaze.

Step 7: Glazing and Firing

After ensuring that your ceramic piece is arid and the underglaze has settled to your satisfaction, the next step is applying a clear glaze over the underglaze work. This will protect the design and enhance the colors’ vibrancy once the piece is fired. Use a clean, broad brush to apply the glaze evenly, or consider dipping the entire piece if the size allows. Be cautious not to disturb the underglaze beneath.

Once you have used the glaze, ensure it is free from air bubbles or imperfections. Then, allow the glaze to dry completely before proceeding to the firing process.

The firing process is critical, as it permanently sets the designs and colors into the ceramic. Carefully place your piece into the kiln, following the recommended temperature settings for both the ceramic and the glaze used. Typically, a bisque firing is followed by a higher-temperature glaze firing.

Monitor the kiln closely, allowing for the appropriate cooling time before handling your finished work. Upon completion, inspect your ceramic piece to ensure it meets your artistic vision, celebrating the culmination of your efforts and creativity.

Step 8: Evaluating the Final Piece

After your ceramic piece has undergone the glazing and firing, it’s time to evaluate the final result. Begin by carefully examining the piece under good lighting to ensure all the colors are vibrant and the glaze has set uniformly. Inspect the texture and finish, providing the surface is smooth and free from blemishes or unintended marks. Consider the overall aesthetic of the piece and how well it aligns with your original design concept.

If necessary, take notes on areas for improvement for future projects, such as color choices or technique adaptations. Observing and evaluating your artwork helps celebrate your success and plays a crucial role in enhancing your skills for future ceramic endeavors. Display your piece with pride, knowing each step of the process has contributed to the unique expression of your creativity.

Step 9: Showcasing and Sharing Your Artwork

With your ceramic piece complete, it’s time to share your creation with others. Consider options for showcasing your artwork, such as local art exhibitions, online galleries, or craft fairs, where you can present your work to a broader audience. Prepare a brief artist statement or description to accompany your piece, highlighting the inspiration, techniques, and materials used in its creation.

Engaging with fellow artists and enthusiasts can provide valuable feedback and foster community around your work. Additionally, consider photographing your piece professionally to capture its nuances and details, which can be shared on social media or your website.

By following these steps, you can confidently embark on a journey of creating beautiful ceramic artwork using underglazes.
