when the glass pieces melted under the glaze.. The microcline caused small, grayish bumps of glaze to form in the glaze applied to the sample. ; Two clay bodies of doubtful strength were those with 50% wheat straw and 30% rice straw added. Very large holes and a number of cracks devel­ oped which made these clay bodies seem quite fragile.

Feldspar was used by the ancient Egyptians in the making of fused glass along with quartz sand, and glass paste was posibly used as imatation green feldspar. References

Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.

Basalt fibers are made from extremely fine fibers of basalt which is composed of the minerals plagioclase, pyroxene, and olivine. The compositions of basalt fibers are shown in Table 11.21.Basalt fibers are produced in a continuous process similar in many respects to that used to make glass fibers.
