    Abstract: PURPOSE: A white glass ball that is a ball of glass containing SiO
    2 , TiO
    2 and Li
    2 O in a specific proportion, thus showing high whiteness, homogeniety and roundness.
    CONSTITUTION: A starting material containing at least 85wt% of a composition consisting of 50W80wt% of SiO
    2 , 8W40wt% of TiO
    2 and 8W17wt% of LiO
    2 is melted in a crucible by heating, cooled rapidly into glass and crushed. Then, the crushed particles are passed through the flame of a burner so that they are melted to form spheres by their surface tension, cooled rapidly into transparent or translucent glass balls. The resultant balls are heat-treated in a temperature range from the glass transition point or softening point to the crystallization point for 5W20hr to form nuclei, further in a temperature range from the nucleating point to the crystallization point to form separately the particle parts 1 having the first phase rich in SiO
    2 and the parts 2 poorer in SiO
    2 content than in the first phase, resulting in optically boundary surfaces 3 caused by difference in refractive index between them.

    Abstract: PURPOSE:To obtain a high-quality display effect, by settling down balls, which are covered with coatings insoluble in a liquid and soluble in a high-resistance organic liquid, in the liquid to form an accumulation layer and charging high polymer materials soluble in the liquid and removing the sheet-shaped coating obtained by eliminating the liquid and arranging display balls most closely. CONSTITUTION:Many display balls 3 covered with coatings such as a wax coat insoluble in the liquid are dispersed and settled down in a low-viscosity liquid 13 to form an accumulation layer. A polyvinyl alcohol (PVA) aqueous solution is charged to this liquid to wrap the accumulation layer of balls 3 and is allowed to permeate into gaps between balls 3, and the liquid is eliminated, and the PVA is hardened. When a sheet 14 obtained in this manner 14 is washed away by toluene and coatings 20 are removed by dissolution, cavities corresponding to the thickness of coatings are generated around balls 3 by removal of coatings, and balls 3 is arranged freely rotatably and most closely in toluene substituted in cavities.
