What is Underglaze?

A potter carefully applies underglaze to a clay mug in a studio.

So, now you’re curious about underglaze. Well, underglaze is like the secret sauce for potters who want to add colors and designs to their pottery before it gets its shiny coat. Think of it as a matte decoration that goes on first.

In the old days, people used colored clay slips for this job. But we’ve gotten fancy since then.

Modern underglazes have something called frit added to them to keep them from shrinking too much when they dry. They’re made with colorants—stuff like stains and oxides—to give you those vibrant colors everyone loves.

Plus, they include water, clay, possibly CMC (that’s short for methyl cellulose), and Veegum to get the consistency just right. What’s cool is that underglazes let the texture of your clay show through while boosting its color big time.

So whether you’re into painting detailed designs or going bold with broad strokes, using an underglaze gives your pottery piece that extra pop without covering up what makes it special in the first place—the texture of the clay body itself.

Preparing Your Pottery for Underglaze Application

Before exploring the world of underglaze application, let’s explore preparing your pottery for this artistic journey. Beginning with carefully cleaning and smoothing surfaces, you’ll ensure a perfect canvas for your creative expression. Whether you choose greenware or bisqueware, each presents its distinct set of considerations, from moisture levels to surface texture.

Cleaning and Smoothing Surfaces

Cleaning and smoothing your pottery is like setting up a blank canvas. For best results, grab a melamine-foam cleaning pad or a typical soft studio sponge. These are your best friends for wiping away any unwanted marks.

They make the surface clean without much effort.

Sanding down rough edges is next on the list. You’ll need sandpaper for this task. Always wear a dust mask; safety first! This step helps create a smooth base for your underglaze to stick well.

A clean canvas is the start of a masterpiece.

Keep everything simple and focus on making that surface as smooth as silk. The goal here? To avoid giving your artistic work a cloudy or dingy look once you apply the underglaze. Keeping it at that milk-like consistency means it will go on nice and even, just how we like it.

Choosing Between Greenware and Bisqueware

Greenware is your go-to for seeing how your design will look on the finished piece. This type of clay is bone-dry, making it perfect for vibrant underglaze colors. It’s like a blank canvas waiting for paint.

On the other hand, bisqueware requires a bit more patience. You’ll need to apply underglaze in layers, almost like using watercolors. Think of bisque firing as prepping your pottery to hold these layers well.

For best results, aim for two to six coats on bisqueware.

Now that you know whether greenware or bisqueware suits your project better, let’s talk about how to put that underglaze on there—brushing, dipping, spraying… The options are endless!
