Choosing between ceramic glazes starts with narrowing by firing temperature, since only glazes compatible with your clay body and kiln schedule are actually usable, then narrowing further by finish and by what the piece is actually for. Testing candidates on sample tiles before committing is what turns a long shortlist into a confident final choice. Most experienced potters settle on a small, reliable set of go-to glazes rather than constantly chasing every new option on the shelf.
Once you’ve been glazing for a while, the problem stops being “what is glaze” and starts being “there are way too many options and I don’t know where to start.” Here at Le Studio Art Space in Mordialloc, we see this exact overwhelm regularly with members past the total beginner stage, so here’s a practical framework for actually narrowing down ceramic glazes.
Start With Your Firing Temperature
Firing temperature compatibility has to be the first filter, before color or finish ever enters the conversation. A ceramic glaze rated for one cone range simply will not fire correctly on a clay body or in a kiln schedule outside that range, so this immediately cuts a large portion of any glaze catalog down to what’s actually usable for your specific setup.
This step is quick once you know your numbers. Check your clay body’s recommended firing range, then only shortlist glazes compatible with that same range. In most studio settings the available house glazes are already filtered this way, which makes this first step effectively automatic if you’re glazing in a shared studio.
If you’re working across more than one clay body or firing range, it’s worth keeping a simple written reference of which glazes suit which range, rather than relying on memory alone. Even experienced potters mix up cone compatibility occasionally, and a quick written check takes seconds compared to the disappointment of a mismatched firing.
This filter also naturally narrows a large catalog down to a genuinely manageable shortlist fairly quickly, which is worth remembering when the sheer number of ceramic glazes on a supplier’s website feels overwhelming. Most of that catalog was never actually relevant to your specific clay and kiln setup in the first place.
Consider The Finish You Actually Want
Once temperature has narrowed the field, finish is usually the next practical filter. Think honestly about what you actually gravitate toward, glossy and saturated, soft and matte, a gentle satin sheen, or something more textured like speckled or crystalline. There’s no wrong answer here, just a question of what suits the piece and your own taste.
It helps to look at your past work if you have any. Many potters notice a pattern once they actually line up their favorite finished pieces, gravitating toward one or two finish families far more than they realized, which makes future glaze decisions faster once that preference is clear.
Lighting also genuinely affects how you judge finish, since a glossy glaze under bright studio lighting can look quite different under softer home lighting where the piece will actually live. Viewing test tiles in a couple of different lighting conditions before deciding is a small step that pays off, especially for a finish you’re planning to use across an entire set of pieces.
It’s also worth revisiting your finish preferences occasionally rather than assuming they’re fixed forever. Many potters find their taste genuinely shifts over years of practice, and a finish that felt unremarkable early on can become a genuine favourite once you’ve seen it used well on the right form.
Think About What The Piece Is For
Function should genuinely shape glaze choice, not just aesthetics. A mug or bowl meant for daily food and drink use needs a glaze that’s food safe and durable once fired correctly, while a purely decorative or sculptural piece has far more creative freedom since it will never touch food or go in a dishwasher.
This distinction also affects how much risk is reasonable to take. An experimental, unpredictable glaze combination might be perfect for a decorative test piece, but it’s a riskier choice for a set of everyday dinnerware where consistency across multiple pieces actually matters.
It’s also worth thinking about who will actually be using a functional piece, since a glaze with a rougher, more textured surface might be beautiful but genuinely less practical for something handled daily by children or used constantly in a busy kitchen. Matching a glaze’s practical qualities to its real-world use is just as important as matching its look to your taste.
Testing Before You Commit
Test tiles exist for exactly this decision-making stage. Firing a small sample of each shortlisted glaze, especially any combination you’re considering layering, shows you the true fired result before you risk a finished piece on it. This single habit prevents more disappointment than almost any other glazing practice.
Small batch trials work the same way for layering. If you’re combining two ceramic glazes, testing that exact combination on a tile first tells you whether it runs, pools, or blends the way you hoped, since layered results are notoriously harder to predict than a single glaze on its own.
Dating and labelling test tiles clearly is a small habit that pays off over time, since a glaze recipe or your studio’s own house glaze mix can occasionally shift slightly between batches. Having an organised, dated record makes it much easier to spot if a favourite glaze is genuinely behaving differently rather than second-guessing your own memory of how it used to fire.
What Competing Guides Leave Out
Most glaze comparison guides talk about color and finish without ever mentioning that identical glazes can genuinely fire differently across different kilns. Kiln hot spots, cooling speed, and shelf position all subtly affect a glaze’s final result, which is exactly why a glaze that looked perfect in someone else’s photo might behave a little differently in your own studio’s kiln.
Budget is the other gap worth naming honestly. You don’t need a huge glaze collection to get strong, consistent results, a focused set of two or three reliable ceramic glazes you genuinely like working with will take you further than a shelf full of options you rarely reach for. Building that palette gradually, testing as you go, is a far more budget-conscious approach than buying broadly up front.
Community knowledge is another resource most guides overlook entirely. Talking with other potters at your own studio about which glazes they genuinely reach for, and why, often surfaces practical insight that no product label or online guide will ever mention, simply because it comes from real, repeated, hands-on experience with the exact same equipment you’re using.
Building A Reliable Go-To Glaze Palette
Most experienced potters eventually settle into a small rotation of favorites rather than treating every project as a fresh decision. That go-to palette usually develops naturally, a glaze you tried once, liked the result, and kept reaching for again because it behaved predictably.
Building toward that point deliberately is worth doing. Every time you test or use a new ceramic glaze, take a note of how it fired and whether you’d use it again. Over a handful of sessions, a genuinely reliable personal palette starts to take shape, and that consistency is often what separates confident, settled glazing from constant first-timer uncertainty.
Even once you have a settled go-to palette, it’s worth leaving a little room for occasional experimentation. Many potters find their palette naturally evolves over years of practice, with a new glaze occasionally earning a permanent spot once it’s proven itself reliable enough to trust on a real project rather than just a test tile.
The fastest way to actually narrow down ceramic glazes is to see and handle the options in person. Explore the glaze options available at Le Studio Art Space’s ceramic studio in Mordialloc and get advice in person.
Frequently Asked Questions
How many different ceramic glazes do I actually need?
Far fewer than you might think. A focused set of two or three reliable glazes you genuinely like working with will usually take you further than a huge, rarely-used collection, and many experienced potters settle into exactly that kind of small rotation.
Is it normal for the same glaze to look different at another studio?
Yes, and it’s a real, well-known effect rather than something you’re imagining. Kiln hot spots, cooling speed, and shelf position all subtly affect a glaze’s fired result, so a glaze can genuinely behave a little differently between two different studios’ kilns.
How do I choose between two glazes that are both compatible with my clay?
At that point it usually comes down to finish and what the piece is actually for, functional daily-use ware versus a purely decorative piece. Testing both on sample tiles side by side is the most reliable way to make a confident final call.
Should I avoid experimenting with unusual glaze combinations?
Not at all, experimentation is part of the fun, just save the boldest experiments for test tiles or lower-stakes pieces rather than a finished set of dinnerware you’re relying on. Many potters find their favorite go-to glazes started out as an experimental combination that worked.
Can Le Studio Art Space help me pick a glaze if I’m still unsure?
Yes, that kind of hands-on guidance is exactly what our studio sessions and classes are for. Bringing your specific project in mind when you visit makes it much easier for us to point you toward glazes worth testing.
