It can be used to cover the entire surface of a clay object, alter its texture, or act as a bonding agent in joining leather hard clay pieces.
Join us as we unravel the mysteries of engobe and underglaze, answering common questions like how many coats of underglaze are needed, whether underglaze can be applied to dry greenware, and what the firing requirements are. Discover the versatility and unique properties of these pottery techniques that will inspire your creativity, transforming your ceramic creations into true works of art.
Engobe vs Underglaze: Exploring the Mysterious World of Ceramic Decoration
While engobe and underglaze may sound like something out of a wizard’s spellbook, they are actually two common techniques used in the world of ceramic decoration. But what exactly is the difference between them? Let’s dive into the fascinating realm of pottery and unravel the mysteries!
Engobe: The Chameleon’s Disguise
When it comes to ceramic decoration, engobe is like a chameleon with a paintbrush. This magical potion, made from clay and other ingredients, serves as a versatile camouflage for your pottery. It can be applied to both greenware and bisqueware, acting as a base layer for glazes or other decorative techniques.
Unlike your favorite charm school, engobe doesn’t consistently cover every nook and cranny of your ceramic piece. Instead, it gracefully dances, revealing glimpses of the clay body beneath, adding texture and depth to your creation.
Underglaze: The Painter’s Palette
Now, imagine you’re a master painter, ready to bring your ceramic canvas to life. Enter underglaze, the painter’s favorite palette of colors. Unlike engobe, underglaze is a colored pigment suspended in a watery potion that can be painted directly onto greenware or bisqueware.
But wait, there’s more! Underglaze is not just limited to brushes. You can dip, sponge, or even stamp your ceramic piece with underglaze, giving you endless artistic possibilities. From delicate watercolor effects to bold and vibrant strokes, underglaze lets you express your creative vision with ease.
Engobe vs Underglaze: The Clash of Techniques
While engobe and underglaze share similarities, they do have some distinct differences that make each technique unique.
Absorption Abilities
When it comes to absorption, engobe is like a thirsty camel in the desert, eagerly soaking into the clay surface. This allows engobes to seamlessly blend with the clay, enhancing its natural color and texture. On the other hand, underglaze sits on the surface, creating a brilliant and opaque layer that doesn’t mingle with the clay below.
Firing Temperatures
Engobe and underglaze also have different firing requirements. Engobes are fired at lower temperatures, typically between Cone 04 and Cone 06, which makes them more compatible with pottery made from low-fire clays. Underglazes, on the other hand, can handle a wider firing range, spanning from Cone 06 to Cone 10, covering both low-fire and high-fire clay bodies.
Final Appearance
The ultimate showdown between engobe and underglaze lies in their final appearance. Engobes tend to create a more subdued and earthy finish, often showcasing the natural beauty of the clay body. On the contrast, underglazes boldly coat your pottery with vibrant or soft hues, allowing your artistic prowess to shine with vivid intensity.
Find Your Perfect Match
Now that you know the difference between engobe and underglaze, it’s time to find your perfect match. If you seek a natural and textured look with subtle color variations, engaging with engobe will bring out the ancient mystique in your pottery. But if you crave the vibrant strokes and endless possibilities of a painter, underglaze will be your trusty companion in the artistic journey.
Whether you choose to dance with the chameleon-like engobe or paint with the exhilarating underglaze, let your creative spirit guide you to new and exciting horizons in the world of ceramic decoration. Embrace the magic, experiment with techniques, and make your mark on the ever-dazzling canvas of pottery.
Happy potting, my artistic companions!

It can be used to join clay pieces, create textured surfaces, or as a decoration medium when mixed with pigments. Clay slip offers versatility in pottery, allowing artists to experiment and explore different techniques to achieve their desired results.
Do You Fire Pottery Before Glazing
Yes, pottery needs to be fired before glazing. The initial firing, called the bisque firing, removes moisture from the clay and hardens it, making it more durable and ready for glazing. Once the bisque firing is complete, you can apply glaze to your pottery and fire it once again to achieve the final desired look.
What Is the Difference Between Slip and Underglaze
While both slip and underglaze are used in pottery decoration, they have distinct characteristics. Slip is a fluid mixture of clay and water or other additives, primarily used for joining clay pieces and creating various decorative effects.

The glaze layer can prevent the underglaze from fully adhering and may cause the colors to blur or appear differently after firing. It’s best to apply underglaze before the glazing process for optimal results.
What Is an Engobe in Pottery
In pottery, an engobe refers to a colored clay slip that is typically applied to the surface of ceramic pieces before firing. Engobes offer artists the opportunity to add color, texture, and visual interest to their pottery, enhancing the overall aesthetics of the final piece.
What Are the Four Ways to Apply Slip
There are four main techniques for applying slip in pottery: brushing, trailing, slip-trailing, and slipcasting. Brushing involves using a brush to apply slip to the desired surface, while trailing refers to pouring slip in a controlled manner. Slip-trailing involves using tools or bottles with a small opening to create intricate designs with slip. Lastly, slipcasting is a technique where slip is poured into a plaster mold to create shapes or vessels.
How Do You Cook Engobe

Once you’re satisfied with your design, apply a clear glaze over the underglaze pencil marks and fire your pottery according to the instructions provided by the manufacturer. The result? A masterpiece that will leave everyone amazed!
Can You Use Slip on Bisqueware
While slip is typically applied to greenware (unfired pottery), it can also be used on bisqueware. Applying slip to bisqueware allows you to add additional decorative elements or textures to your ceramic pieces. Just remember to score and moisten the surface of the bisqueware before applying the slip for improved adherence.
What Is Grog in Pottery
Grog refers to a specific type of material, typically crushed fired clay, that is added to clay bodies. It helps to improve the overall workability, reduce shrinkage during drying and firing, and enhance the resilience and strength of the final ceramic piece. Grog can also create interesting textures and visual effects in pottery, making it a popular choice among ceramic artists.
