Producing a Unique Crystalline Glaze for a Ceramic Vase
Did you ever notice the texture of artistic styled vases made from porcelain, ceramics or other material? Along with that, and did you ever wonder how that effect was created? If you want to know the answer to that, whole world of resources is available to you via Internet. Some glazes produce a smooth finish, and others produce a crystal like finish for a fine piece of pottery such as a porcelain or ceramic vase.
Described in the following paragraphs is the crystallization process while forming a crystalline glaze for a vase. The crystallization process can be very technical in nature, but can also be explained in a simple way. It is most often used on porcelain, but has been known to be used in ceramic glazing as well.
One more recent crystalline process used by Avril Farley produces a new variety of textures and colors mixed together. The finished product of this process usually represents a glaze textured of crystals shaped like lichens and/or three-dimensional fans and feathers.
The tricky process of creating crystals in a glaze for a ceramic vase or other pottery starts by the reforming of cooling oxides after they have melted. Some crystals formed are so small they cannot be seen with the naked eye, but group together to add form to crystals being made. Larger crystals grow up to 15 cm in length, and are often a different color than that of the ceramic vase itself. On the smooth surface of a ceramic vase crystals in the glazing process form and fan into halo shapes interconnected often with one another as they expand. Variations of colors form within the forming crystals on the vase surface.
Furthermore, on thicker areas of the ceramic vase, such as the base or the rim, shapes that look like fibrous fans fill in the depth of these areas. This is occurs by allowing adequate cooling time for crystals to form within the glaze. If during the cooling process, the temperature is held around 1090 degrees, the crystals will begin to form as simple needles and expand into dual ax heads which can be frozen to retain this shape upon rapid cooling. Fuller and rounder crystals are formed during the following order of cooling times, which usually last from between three to eight hours.
The different steps of the glazing process serve a variety of different purposes. For example, the Ferro Frit glaze helps make the melt quickly at high temperatures. The rapid heating and cooling during this process helps crystals continue to form by preventing a body glass film to be formed which would deter larger crystal formations from developing. Crystals develop during the cooling process when oxides isolate themselves from the surround glazing surface area. Zinc silicate is the most common element of the larger glazes that form.
There is no end to the art texture that the crystalline glazing process can bring to a ceramic vase or other pottery.
This is only a tiny representation of this particular glaze process. If you want to know more about how to make a ceramic vase and the crystalline glazing process, you can type "ceramic pottery" or similar search word into your Web browser.
You are sure to find all the information you need for the creation of a ceramic vase and how to glaze them to form beautiful, flowerlike crystals for a unique vase finish. Furthermore, if you are looking for recipes for glaze, such as for the crystalline process, you will find that on the Internet as well.
