Here is how to glaze pottery in short: prepare clean bisque, wax the foot, stir the glaze, apply it by dipping, pouring or brushing to an even, moderate thickness, clean the foot, and fire to the cone on the jar. Each step below explains why it matters and what goes wrong if you skip it.
This guide is research-based. It draws on glaze maker instructions (Mayco, AMACO), Seattle Pottery Supply's dipping tutorial, Ceramic Arts Network's application methods and the Digitalfire reference, not on our own firings.
Before you start
- Bisque fired ware: most glazes are applied to bisque. AMACO, for example, asks for bisque fired to cone 04 for its cone 5/6 glazes. Some products, such as Mayco Stroke & Coat, can also go on greenware. See bisque firing.
- Glaze rated for your cone: the glaze and the clay must match the firing. Our clay and glazes hub explains cones.
- Supplies: wax resist, a damp sponge, soft glaze brushes or a fan brush, a stir stick or palette knife, tongs for dipping, and a bucket or wide container.
Can you glaze pottery in a regular oven?
No. A ceramic glaze is powdered glass-making minerals, and it only turns into glass in a kiln. Even the lowest-fire glazes in this guide mature around cone 06, about 1,828°F (998°C) on Orton's chart, while a home oven tops out at a few hundred degrees Fahrenheit. In a kitchen oven the glaze simply dries back into powder, and it will rub off, flake and leave the pot porous.
Products sold as "oven-bake" ceramic paints are a different thing: they cure at kitchen temperatures, but they are not glass, and their makers' labels decide whether they are suitable for food or dishwashers. Unfired acrylics such as Duncan Bisq-Stain are decoration only and do not waterproof a pot. If you have no kiln, a community studio, or one of the pottery supply shops that fire customers' work by the shelf, is the practical route. Our pottery oven vs kiln page explains the temperature gap in detail.
How to glaze your own pottery at home: setting up
Glazing at home needs less space than throwing, but it needs to be tidy. Work on a wipeable table covered with a plastic sheet or canvas, keep a bucket of clean water for sponges, and keep glaze jars closed between uses so they do not thicken.
Glaze dust contains silica. Wipe spills while wet, mop instead of sweeping, and never sand dry glaze indoors. Mayco's safety sheet says mixing dry glaze or spraying it should not be done without a NIOSH-approved respirator. If you do not own a kiln yet, many community studios fire members' ware by the shelf.
Most home potters start with ready-made liquid glazes. If you later move to mixing your own from powders, our glaze materials guide explains what each raw ingredient does, including the frits that most commercial recipes rely on.
The three rules of glazing
There is no official list, but three rules turn up in almost every maker's instructions and every studio's posted guidelines. Follow them and most first-firing disasters disappear.
- Match the cone. The glaze, the clay and the kiln firing must all be rated for the same cone. A low-fire glaze fired at cone 6 can run and change color; a cone 6 glaze fired at cone 06 never melts.
- Keep the bottom clean. No glaze on the foot or the lowest edge, and a wider bare band for glazes that move. Glaze on the bottom fuses the pot to the kiln shelf.
- Get the thickness right. Follow the coat count on the label and aim for roughly credit-card thickness. Too thin looks dry; too thick runs, crawls or crazes.
Two habits back them up: start with clean, dust-free bisque, and test new glazes and combinations on a tile before trusting them on a finished piece.
Step 1: Prepare the bisque
- Handle bisque with clean, dry hands; oil and lotion can make glaze pull away (crawl) in the kiln.
- Wipe the piece with a barely damp sponge to remove dust.
- Let it dry for a few minutes so the surface absorbs glaze evenly.
Step 2: Wax the foot
Wax resist is a water-based coating that repels glaze. Brush it on the bottom of the pot and up the lowest part of the foot, plus anywhere a lid touches its gallery. Mayco says its AC-302 Wax Resist burns off in the kiln and leaves the surface as it was before firing. Let it dry before glazing.
AMACO warns that its wax used over dipping glazes, or over glazes without gum, may peel the glaze off. Wax bare bisque first, or test before waxing over unfired glaze.
More detail is coming in our wax resist guide.
Step 3: Stir the glaze
Glaze settles. Stir from the bottom until no sludge remains, slowly so you do not whip in bubbles. Crystal glazes need extra care: Mayco says crystals in its Stoneware crystal glazes settle to the bottom of the jar and need a good mix before use, and to re-stir between coats.
Step 4: Choose a method
Dipping
Dipping is the fastest way to an even coat, and the most common method in studios. Grip the pot with glaze tongs on its strongest area, lower it into the bucket, and lift it out after a short count. Seattle Pottery Supply suggests counting to three, then shaking off the excess. Longer dips give thicker coats. Dipping needs a deep bucket of glaze, so it suits potters who glaze often; our dipping glaze guide covers it in depth.
Pouring
Pouring is how most potters glaze the inside of mugs, bowls and vases. Pour glaze into the pot, roll it so it coats the whole inside, then pour it back out in one smooth motion. Glaze the inside first and the outside second. Ceramic Arts Network suggests a slightly thinner mix for pouring so overlaps do not get too heavy. A dedicated guide to glazing inside a mug is planned.
Brushing
Brushing is the easiest method at home, because you only need a pint jar. Use a soft, full brush and lay glaze on in long, even strokes instead of scrubbing. Let each coat dry until the shine is gone before adding the next. Most commercial brushing glazes need two to three coats; some reactive and textured glazes ask for more (Mayco says three to four for Elements and 4+ for a saturated Black Walnut). A soft fan brush holds plenty of glaze and helps smooth streaks on large areas.
Spraying
Spraying gives smooth gradients but creates fine mist you can breathe in. Ceramic Arts Network says spraying needs a ventilated spray booth and a properly fitted respirator, and should be built up in several thin coats. Mayco prints a no-spray instruction on its labels for this reason. For most home potters without a booth, skip spraying.
Step 5: Get the thickness right
Thickness causes more glaze problems than any other factor. The Digitalfire reference gives "credit-card thickness" as a target for common glazes, and cites a stoneware mug example with roughly 0.5 mm of fired glaze inside and out. Thinner looks dry or pale; thicker can run, crawl or craze.
- Check with a fingernail: scratch a small spot near the foot after the glaze dries. The coat should look like a thin card edge, not a thick crust.
- Respect the label: Mayco warns that heavy SW-001 Stoneware Clear can increase crazing, and that its Zinc-Free Clear may turn cloudy if applied too thick.
- Thin toward the bottom: for glazes the maker says will move, such as Mayco SW-132 Mirror Black, reduce thickness on the bottom third of vertical pieces.
Too much glaze on pottery: how to fix it before firing
If you see too much glaze on pottery before it goes in the kiln, fix it now; it is far harder after firing. For a few drips or a thick band, let the glaze dry and gently scrape or sponge it back to an even layer, wearing a mask if you create dust. If the whole piece is too heavy, wash all the glaze off under running water outdoors or over a bucket, let the bisque dry fully (a day or more), then glaze again.
Once fired, heavy glaze that ran onto the shelf can only be ground off. Use kiln wash on shelves to make that easier.
Step 6: Clean the foot and load
Wipe any glaze off the waxed foot with a damp sponge, and wipe the lowest edge clean too. Glaze left on the bottom will fuse the pot to the kiln shelf. Leave a wider bare band for glazes that run. Then fire to the cone printed on the jar.
Common faults and causes
| Fault | What it looks like | Common causes |
|---|---|---|
| Running | Glaze drips to the foot or shelf | Too thick, over-fired, or a fluid glaze on the lower third |
| Crawling | Glaze pulls into islands, bare clay between | Dusty or oily bisque, very thick coats that crack while drying |
| Pinholes | Tiny holes in the fired surface | Thin or uneven coats on porous bodies, gases escaping, under-firing |
| Crazing | Fine web of cracks | Glaze and clay shrink differently; heavy clear coats can add to it |
| Cloudy clear | Milky clear glaze | Clear applied too thick |
Each fault has its own page: glaze running, glaze crawling, glaze pinholes and glaze crazing.
Common mistakes
- Glazing dusty bisque straight from the shelf.
- Not stirring, so the first pot gets water and the last gets sludge.
- Adding the next brushed coat while the last one is still wet.
- Skipping test tiles for new glaze combinations.
- Leaving glaze on the foot.
Safety and food use
Treat glaze like any fine mineral dust: wet clean, no eating or drinking at the glazing table, and a NIOSH-approved respirator when mixing powder. For mugs and plates, use a glaze labeled for dinnerware by its maker and fire it to the stated cone; the label describes the maker's test conditions, so results on your pots depend on your clay, thickness and firing.
What you need
If you are still choosing glazes, start with our clay and glazes hub, which covers brands, labels and jar sizes. Mayco Stroke & Coat, reviewed on our Stroke & Coat page, is the easiest brushing glaze to begin with. For the kiln itself, see the best kilns for home pottery.
