Question:

How do I apply glaze?

Layering glazes

Some of the most interesting effects can be obtained by layering glazes. Try dipping an already glazed pot part of the way into another glaze. This greatly increases the chance of the glaze running, so don't try to doubling up the glaze all the way to the bottom of the pot. The best results usually come from trying a matt glaze over a gloss glaze. If the first layer of glaze isn't good and dry before applying the second, there is a good chance the glaze will crawl. A piece of bisque can only absorb so much water before it becomes saturated, so let it dry first. Anytime you notice the glaze cracking or peeling, it's probably too thick, so you're best off washing all the glaze off and starting over. Keep in mind that the glaze that falls off your piece can land on somebody else's and ruin it also.

Thin pieces

When glazing a thin piece, glaze the inside, making sure you don't over apply, as the thin walls will absorb a lot of glaze, then wait for it to dry thoroughly before glazing the outside. Otherwise the clay may be saturated and glaze won't absorb and stick to the outside. Some people wait overnight.

Handy glaze pourer

Handy Glaze Pourer: The green straight handled cups that come with dry
detergent can have the
handle bent straight down by heating over a flame. They then will hang over
the edge of your glaze
bucket, and they pour a nice small stream from the corners of the cup.

Save little dabs of glaze

Be sure to save those little dabs of glaze left oven in a jar. You can pour the excess in a larger jar and save it for later. You probably would not want to use it as a decoration after mixing all the colours together, but you can use it inside of something such as a flower pot where it will not be seen.

‘low-fire'

The types of glazes used in hobby ceramics fall under the ‘low-fire' category since the kiln only uses the medium temperature ranges to mature the glazes

To remove glaze from fired pieces

To remove glaze from the bottom of pieces that you want to dryfoot, mount a piece of sandpaper on a board or table top and simply rub off the glaze in that area.

Test tile attributes

Texture: It is generally a good idea to add texture to part of your test piece so you can see how the glaze will respond to texture and carvings.
Holes: Put a hole somewhere to hang your tiles on a wall board or to hang off the handle of the bucket.
Marking: Put some type of word or code that reminds what glaze this was, what clay it was on, and perhaps even firing temperature. Or simply number them and keep the details in a notebook by number.(One way to number is with one of those adjustable rubber stamps, the ones with wheels to change the number).
Dipping: Usually best to do three dips. First dip covers the whole area. Second dip covers 2/3 of the area. Third dip covers half the previous dip. So you have 1/3 with 1 coat, 1/3 with 2 coats, and 1/3 with 3 coats. (Keep the thickest coat the furthest from the kiln shelf in case it runs)
Layer multiple glazes:
For example, take a circle, dip 1/3 in glaze 1, dip 1/3 in glaze 2 (overlapping glaze 1), dip 1/3 in glaze 3 (overlapping glaze 2 on one side and glaze 1 on the other). So you get 3 solid colors, plus 3 overlap colors. Another example: take a square, dip ½ in glaze 1, turn, dip ½ in glaze 2. At this point you have two solids, plus 1 solid over the other. For the 4th section you could try layering the opposite way (glaze 1 over glaze 2 instead of glaze 2 over glaze 1), have an underglaze coat, or introduce a texture or a third color.
Other layering effects: For example, undercoat a section with underglaze, or paint an iron oxide and a cobalt oxide line so you can see if the oxide runs or stays put during firing.

It is important that you do not over-apply transparent glazes since too much colour will give a milky finish over colours

Frit

Those little chunks of colour that are found in crystal glazes are called frit. They are pieces of dried glaze.
