Porcelain clay is perhaps the most renowned form of clay for creating delicate objects such as fine bone china or figurines. In its raw state, it is typically white or gray in color. It is also very soft in texture and more flexible or 'plastic' than the other kinds of clay. Due to its delicate, soft nature, it is not easy t…

Therefore, it may be advantageous to replace silica containing raw materials such as flux (feldspar), silica and part of clay by blast furnace slag to produce ceramic recipes with desired properties. The aim of present work is to investigate the feasibility of producing alumina porcelain insulators from air blast furnace slag (ABFS) and γ-Alumina.

Mix the water, glue, and glycerin in your saucepan over medium heat. The goal is to heat it up and mix it until it becomes creamy and smooth. Make sure to remove any clumps. After this, you can begin slowly adding the cornstarch as you continue mixing. The mixture should begin to take on a cottage cheese form.

Section snippets Material and methods. The chemical composition of the employed starting materials is reported in Table 1.
