How do you make ceramic glaze with powder?
Sometimes I just get the dry for it to be a little bit cheaper. So it has directions right on here
In order to make your own ceramic glaze, simply mix a glaze powder with water. It is a relatively simple process. The overall process involves measuring out water, mixing the glaze powder into the water, sieving, adjusting viscosity or density, and letting the glaze sit before it is applied to your bisque-ware.
GLAZE MIXING
A rule of thumb is that 1kg dry powder glaze makes up approximately 1.25 litres dipping glaze. Glaze may be “set up” using approximately one tablespoon of Calcium Chloride or Glaze Set up Solution per 5 litres.
In this case soda feldspar silica whiting zinc oxide and kaolin potters prefer to measure
Start by combining equal parts of ceramic powder and glue to create a batter. Take an old earthen pot and start putting the batter around it; you can use your hand to create a rough texture or you can use a brush to create a smooth one. Let the batter dry for a few hours and then apply ceramic paint.
As a general rule of thumb, for 1 lb of dry glaze powder, use 11 ounces of water for dipping glaze, 8 ounces of water for spraying glaze, or 7 ounces of water for brushing glaze. Or, 25 lbs makes about 3 gallons.
- Too much flux causes a glaze to run, and tends to create variable texture on the surface. ...
- Too much silica will create a stiff, white and densely opaque glass with an uneven surface.
If you want your matte glaze to be satin, or only slightly glossy, just add a small amount of Silica. This will move the dot only slightly to the right on the Stull chart. Typically a SiO2:Al2O3 ratio between 5 and 6 will give you a satin glaze. If it's too matte, add some Silica.
Approximately 8 to 11 ounces of water per pound of dry glaze will be needed, but the amount needed varies per glaze. Add additional water if glaze is too thick immediately after mixing.
Dry mix the ingredients with a spoon until well dispersed. For 100 grams of material, add about 50ml of water (less if your glaze has little or no clay).
How do you calculate glaze?
16.1.5.
Glaze formulas are often given as percentages of the various oxides. In order to find out the chemical formula, the rule is to: Divide each oxide by its molecular weight! In the appendix you will find the molecular weight of glaze oxide and materials.
For most glazes (see individual product descriptions for exceptions), sprinkle the powder into a suitable container of water, stir, then sieve through an 80's lawn or finer. Leave to settle overnight and pour off surplus water. Stir, then if necessary add water to achieve the desired consistency.
The answer to your frustrations is a powder glaze!
Powder glazing goes on wet, dries completely and you remove the dry powder in only the areas you want. No more wiping and reapplying wet glaze. Powder glazing furniture adds depth, dimension, and beauty to furniture and cabinets.
FELDSPAR is probably the single most commonly used glaze ingredient. It is a natural mineral, derived for granite. It is a source of SILICA, ALUMINA, and a relatively smaller amount of FLUX. ALUMINA is added to glazes by the addition of BALL CLAY, KAOLIN, and FELDSPAR (discussed above).

Ceramic powder is a traditional ingredient in building and plastering mortars. It is produced by crushing natural bricks and is baked at temperatures of up to 900oC, to give it pozzolanic properties. Used since Roman times, primarily to produce top grade mortar.
Ceramic coating is a high-solid paint product which is concentrated with ceramic powder. Initially developed for the aerospace industry, the process is now used throughout the auto industry on components that include exhaust manifolds, headers, mufflers, and intake manifolds.
There are two ways of synthesizing ceramics: Dry method (solid–solid method) Wet method (sol–gel, hydrothermal, combustion and coprecipitation methods)
Glaze is made of glaze minerals suspended in water, so adding more water will make it more liquid. It's important not to make glaze too thin. If it's too thin, you won't get the kind of glaze coverage you need. So, the short answer to the question is that you can add water to glaze to make it thinner.
Soda (sodium carbonate or sodium bicarbonate)—I use a mixture of baking soda and soda ash. This solution tends to result in more subtle gray/blue glaze hues, subtle flashing marks, more directional effects, and softer and flatter glaze texture on the surface.
What does Epsom salt do in a glaze?
Epsom salt additions can be invaluable for glazes, its enables creating a thixotropic (gelled) slurry that applies evenly, holds in place and goes on in the right thickness on porous or dense bisque ware. When the slurry has a sympathetic specific gravity, about 2g per gallon of epsom salts should gel it.
Glazes need a balance of the 3 main ingredients: Silica, Alumina and Flux. Too much flux causes a glaze to run, and tends to create variable texture on the surface. The texture may vary from shiny, where the glass is balanced, to matte where the excessive flux oxides may form visible, possibly lumpy, crystals.
Wearing a suitable mask, sprinkle the glaze powder into a suitable container of water and stir thoroughly. Leave to settle overnight and pour off surplus water. Stir, sieve through an 80 mesh or finer sieve, then add water if necessary to achieve the desired consistency.
They are thus particularly suitable for use as soot filters, filters and heat exchangers for gases and some liquids, heatable catalyst supports and porous ceramic electrodes for chemical process engineering.

Mix 1 part medium to 1 part underglaze powder to create a brushable colour. You use one part colour stain to two parts medium. The result is a very fluid mix that it lovely to paint with.
What makes ceramic glaze shiny?
It's really easy to convert a matte glaze to a glossy glaze, just by adding one ingredient – Silica (SiO2). The 3 photos above are pairs of test tiles where the only difference between each pair is the addition of Silica. Matte glaze on the left + Silica = glossy glaze on the right. Pretty cool, right?
Raw materials of ceramic glazes generally include silica, which will be the main glass former. Various metal oxides, such as sodium, potassium, and calcium, act as flux and therefore lower the melting temperature. Alumina, often derived from clay, stiffens the molten glaze to prevent it from running off the piece.
One of the major ingredients to make this happen is gelatin. Just about all mirror glaze recipes will contain some amount of it and replacing gelatin isn't easy.
Because most ceramic powders do not react much with water, a clay or glaze slurries can be stored and the rheological properties do not change. However if a soluble material is added to glaze suspension the usual result is a destabilizing (change over time) of its flow properties (viscosity, thixotropy).

Are ceramic powder and white cement the same? Not at all. White cement mainly contains line stone. Where as ceramic could be zirconia, alumina etc.
