In nearly every market there are always businesses that can supply customers with whatever they need, but the cost can be prohibitive. For those who are interested in adding to their knowledge of creating ceramics, glazes are an area they often neglect. Learning how to create an original glaze is a daunting process, and it requires basic knowledge of how they are made. The student will not be able to find an easy online course, so studying with a professional is usually the best way to learn.
The composition of glazes is a complex subject, and the student must learn how the different factors will affect the final product. If it is just a matter of learning how to take a clear glaze and add color, it can be a simple matter of learning where to look for additives to commercially prepared glazes. A new artists will find that many companies offer a choice of colors, and most of them can be ordered and delivered within a few days.
Different glaze mixtures create a different texture on the final product after firing, and knowing how to select the right glaze is the first step. Students who are just learning about the topic can find it overwhelming because there are many choices, and those who want to create their own glaze for a special project will need to know a bit about chemistry and mixing.
Artists are generally willing to share their knowledge, and some of them teach formal courses. Learning to formulate glazes is an advanced course, but that is only because many new students working with clay are generally interested in forming pieces with simple decorations. The choice to learn about the basic formulas and combinations to create different glazes is one that is only taken when the student finds they have advanced enough to truly appreciate the finishing effect glazes will have on their pieces.
