Many people want to know what the glaze is. Glazing is a technique that requires:
Color Glazes are a type of glass that are specially made to stick onto pots and other ceramic surfaces. When molten, this specialized glass is stiffer than glass that is poured or blown is. This is important, as otherwise, the glaze would run off the vertical surfaces of the pots when brought up to temperature in the kiln.
Clay glaze colors come in a huge array of colors, the result of minerals and inorganic compounds. The most commonly used colorants are iron oxides, cobalt oxide, chromium oxide, copper oxide, and copper carbonate. A glaze's color may also be affected by the firing process. If the atmosphere in the kiln has plenty of oxygen, it is called an oxidation firing. If the atmosphere has very little oxygen, it is called a reduction firing. The amount of oxygen present in the kiln can drastically change a glaze's color. For example, a basic glaze using copper carbonate to color it will be turquoise if fired in an oxidation atmosphere, or bright red if fired in a reduction atmosphere. Most glazes are semitranslucent, except blush transparent glaze and laurel green color glaze.
Ceramic glazes come in a wide range of colors, allowing artists and potters to create various effects and achieve their desired aesthetic. Here are some common glaze colors used in ceramics:
White: White glazes provide a clean and bright appearance. They can range from opaque to translucent and are often used as a base glaze or for highlighting specific details in a piece.
Clear: Clear glazes are transparent and allow the natural color of the clay body to show through. They provide a glossy finish and are commonly used to enhance and protect the underlying colors or designs.
Blue: Blue glazes can range from pale pastels to vibrant cobalt blues. They are often associated with traditional and historical ceramic styles, such as blue and white porcelain.
Green: Green glazes offer a range of shades, from earthy greens to vibrant emerald tones. They can evoke natural landscapes and are popular in pottery inspired by nature.
Brown: Brown glazes can mimic the appearance of natural materials like wood or evoke warm earthy tones. They can range from light tan to deep chocolate browns.
Black: Black glazes provide a dramatic and bold look. They can range from matte to glossy finishes and are often used to create contrast or highlight specific elements in a piece.
Red: Red glazes can vary from bright, fiery reds to deeper maroon or rust tones. They can create rich and warm effects, reminiscent of earth and fire.
Yellow: Yellow glazes range from pale lemon yellows to intense golden hues. They can bring a sense of warmth and brightness to ceramic pieces.
Orange: Orange glazes offer a vibrant and energetic appearance. They can range from light apricot shades to deep, fiery oranges.
Purple: Purple glazes provide a sense of elegance and royalty. They can range from light lavender to deep violet or plum tones.
These are just a few examples of glaze colors available for ceramics. Additionally, artists and potters can create custom colors by mixing different glazes or experimenting with glaze application techniques. The firing process and the type of clay used can also influence the final appearance of the glaze color.
