Yes, as long as the glazes are meant to be fired to the same cone. Putting a cone 6 and a cone 10 glaze on the same pot would not be a good idea. But putting two, three, four, etc. glazes of the same cone on one pot is perfectly fine. Just understand that glazes may be stable by themselves, but when another glaze is added on top that may create instabilities such as crazing or running. The biggest problem I have had with combining glazes on one pot is running. Just make sure to put the pot on stilts or on a waste slab so you don't have to grind glaze off the kiln shelf.

Can you use more than one type of glaze on each clay pot?
Yes you can.
How does red clay differ from gray clay?
There are different minerals present in each clay body. Red clay typically has a higher iron content than grey clay.
Why do you glaze a pot?
this is for dry glazeChoose a container that is two times larger than the total amount of finished glaze. Select a 1- to 5-gallon container. If you're making 1/2 gallon of glaze, use a 1-gallon container. This allows enough room to coat the pottery.2Adhere masking tape 1/4 to 1/2 inches from the bottom of the pottery. Placing the tape around the base of the piece helps later on during the firing process.3Pay attention to the cone number. There are a variety of kilns for firing pottery. Each uses the cone number as an indicator for the kiln type. Unless experimenting, use the specific type recommended.4Create a caramel dry glaze (cone 10) by combining 50 grams of pumice stone and 50 grams of rottenstone. For a satin green dry glaze (cone 10) replace the rottenstone with 14 seltzer tablets and 10 grams of talcum powder to the 50 grams of ground pumice. Grind the solid materials into a powder form5Measure dry ingredients one at a time. Pour them into the mixing container. To produce the best results, weigh all chemicals accurately.6Secure the sealable lid on the bucket. Place the container on its side and gently roll it on the floor for 1 to 2 minutes. Allow the dust to settle for at least 1 minute. Remove the lid after the dust has settled.7Apply the glaze to the pottery by dipping the piece into the dry glaze.
How many times do you have to fire your clay art project if it is glazed?
You usually fire the object twice. The first time, after the raw clay piece has completely dried. This is called the bisque fire. It is a lower temperature firing that makes the clay harder, through a chemical change that comes with the heat. Sometimes, with low fire earthenware, the bisques is actaully fired higher than the glaze firing. The piece is then strong enough to easily handle for the application of the glaze, which is a suspension, in water, of glass making chemicals , such as silica and other color making chemicals . The piece is then fired once more to a higher temperature to melt the glass making chemicals. The piece undergoes another chemical change at the high temperature, which renders the pot more vitreous, making it very strong. There are types of pottery that is created by once firing even when it has glaze. It is difficult to put the glaze of the unfired bone dry pot but some traditions such as Korean onggi jars are done this way. Chun pottery was once fired as well. Some salt and soda and wood fired glazed work is done this way as well. This is easier becuase the glaze is an atmospheric glaze rather than applied as a liquid. When once firing the pot must be very slowly and carefully heated for the first 1000 degrees F or so so the pot does not explode. Much historic pottery such as ancient Greek looks to lay people as though it is glazed but it was slip decorated and once fired. Sometimes pottery is fired many times more than this. Ming vases were done this way with each successive glaze being a lower temperature one and the final glaze being the very low temperature silver or gold metallic luster glazes. It is often used to get layered glaze effects and effects where glazes fire at very different temperatures.
What causes of crawling in ceramics?
Crawling occurs for a number of reasons, but basically the glaze or slip used shrinks at a faster rate than the clay body when fired. In my studio it occurs most commonly when glazes containing a partial amount of clay is applied too thick or when slip is applied on top of a glaze. There are some glazes however that are formulated to crawl giving a look similar to dried and cracked mud.

Why does clay hold more water than sand and silt?
Clay is not more porous than sand. Porous means permeable by fluids, so, sand is more porous than clay.

Why does clay swell more than sandstone?
When you add water to clay you will notice more swelling than you will when adding water to sandstone. This is due to clay being more permeable than sandstone. This allows clay to absorb and retain water at a quicker rate.
Does dry clay weigh more then wet clay?

Why are clay cliffs more vulnerable than granite cliffs?
It is because granite cliffs are stronger and more stable than Clay cliffs since Clay would break down easly from erosion.
