Can you mix two glazes together?

Mixing brands of glaze can work, particularly if they have the same properties. For example, layering glazes from the Spectrum 1100 range with and Amaco Potters Choice glazes can work well. It's also possible to blend glazes from different brands together to create a new color.

How do you combine glazes?

Mix the Wet and Dry Ingredients

Slowly sprinkle the dry ingredients into the glaze bucket, while at the same time stirring up the water either with your gloved hand, a whisk, or a mixer drill attachment. The trick here is to get every particle wet without introducing any air into the water/liquid glaze.

Can you layer glazes?

Layering multiple glazes will build up increasing amounts of glaze on your pot. If the glaze is too thick, it will eventually begin to crack and fall off the work.

Can you overlap glazes?

Glaze overlaps can extend your glaze library dramatically. Two glazes (A and B) can yield six different surfaces if you add the four overlaps: A over B (A/B) and its inverse (B/A), as well as self overlaps (A/A and B/B).

Can you put glaze over glaze?

You can not glaze again over an overglaze without completely melting and removing it.

Mixing Glaze liquid

How many layers of glaze do you need?

Typically, three coats are applied. Each dries slowly, hardening as it does so (the glazes contain binders). This provides a stable base for the next one.

Why do glazes crawl?

Crawling is caused by a high index of surface tension in the melting glaze. It is triggered by adhesion problems, often caused by bad application. It occurs where a glaze is excessively powdery and does not fully adhere to the surface of the clay.

How long should glaze dry before firing?

Some potters will put their glazed ware straight into the kiln and fire it immediately. However, glaze contains water, and this is absorbed by bisque ware when glaze is applied. Ideally, leave your pottery overnight after glazing to allow this water to evaporate. Or add a pre-heat to your firing schedule.

Can you mix glazes to make new colors?

The quickest way to get more colors is to make half-and-half mixes of your current glazes. Combining 1/4 cup each of any two glazes will give you enough glaze to cover a test tile, small plate or bowl. The results can be surprising.

Do I need to sieve glaze?

Sieves are important in ceramics for removing particulates and agglomerates from glaze, engobe and body slurries.

Can you layer low fire glazes?

Amaco Low-Fire Glazes can also be layered with great results!

How much does 5lbs of dry glaze yield?

5 Lbs. of dry glaze needs approximately half a gallon of water (every glaze is different, check the label) and will yield about three quarts of glaze. 10 Lbs. of dry glaze needs approximately one gallon of water and will yield about a gallon and a half of glaze.

Can you layer earthenware glazes?

After treating myself to some glaze tongs, layering glazes has become much easier. I simply dip in the first glaze and leave a few minutes to dry. Once the sheen has gone and it's touch dry I dip in the second glaze. The next day I rub over the tong marks and wipe clean the base of the pot.

How much dry glaze do I need for a 5 gallon bucket?

5 Gallon Bucket - 25 pounds of dry material approximately fills a 5 gallon bucket with glaze. NIOSH Approved Respirator • Drill with mixer attachment • 1 pint for every 1 pound of dry material.

What happens if you over fired glaze?

Overfiring results in glazes that begin to run. The glaze coat may be thinner at the top of the pot and thicker at the bottom. Glaze may even run off the pot and drip onto the kiln shelf or other pots. Seriously overfired pots may show ​pinholing and pitting as the glaze reaches evaporation temperature.

Can you fix pinholes in glaze?

The Glaze Was Fired Too Quickly

In that case, the glaze melt doesn't have enough time to run over and eliminate the gases. If you see more pinholes in the thicker parts of your pottery pieces, you can fix the issue by firing more slowly.

Why is my glaze cracking before firing?

When a glaze cracks as it dries on a pot, it usually means that the glaze is shrinking too much. This is normally caused by having too much plastic material (ball clay) in the glaze.

Can you layer different colors of glaze?

Layering Glazes

Well, the short answer to that question is that you can. It's ok to add more than one color glaze to your pottery. What this looks like when it's fired, will depend on the glaze you use. Some glazes are static, which means that they will stay pretty much in the same place that you applied them.

What happens if you put glaze on too thick?

Fluid melt glazes will run off ware if applied too thick. Glazes having a thermal expansion lower than the body, and thickly applied on the inside of vessels, can fracture the piece during kiln cooling. Those having a higher expansion than the body will often craze if applied too thick.

How many times should I dip glaze?

Typical amount of time for dipping is 5 seconds. For darker colors, dip an additional one second in glazes that do not "move" too much. Using two glaze types dipping is not recommended, being that it is hard to determine how liquidy the combination of the two glazes will be.

How thick should brush on glaze be?

It is highly recommended to use a Ford Cup or Viscosity Cup and aim for run-out time of 15 to 20 seconds. After application the glaze layer should be as thick as the diameter of a standard steel paper clip.
