By the glass are in ratio (40-x): 20Al2O3:20CaO: B2O3 20Na2O: xFe2O3. When x is the quantity entered in the quantity of various Fe2O3 is 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 mol%, the results showed that, for example, have a glass of yellow brown colors that correspond to the spectrum of Fe3 + suck at 450 nm and co CIE color system on di Internet L * a * b * from UV-testers boen specification grow growth parameters that rafo (a *) to be sur.Is between 0.0401 0.1290 and up-(b *) between 0.0821 to 53.4558 best value for density and refractive index values have similar trends. With the increasing trend of increases when the quantity of Fe2O3. Both the density and refractive index values, the density in g/cm3 2.4662 range to 2.4918 and refraction index is in the range 2.4918 through 2.4662.

The glass was prepared in the ratio (40-x) B2O3: 20Al2O3: 20CaO: 20Na2O: xFe2O3 when x is the amount of Fe2O3 put into volume were measured 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 mol% result was found. For example, the glass is colored yellow, brown, corresponding to the spectral absorbance at 450 nm of Fe3 + and Coca Auditorium, Connecticut color in the CIE L * a * b * from UV - Visible million. Spectrometer photometer which (a *) will be between about 0.0401 - 0.1290 and the value (b *) will be between 0.0821 to 53.4558 of the density and refractive index values ​​are likely similar. By increasing the amount of Fe2O3 increase both the density and refractive index. The density values ​​are in the range of 2.4662 to 2.4918 g / cm3 and the refractive index in the range of 2.4662 to 2.4918.

The glass was prepared in the ratio (40 - x) B2O3: 20Al2O3: 20CaO: 20Na2O: xFe2O3 when x is the amount Fe2O3 put in. It is 0.0 0.2 0.4,,,, and 0.6 0.8 1.0 mol%. The results show that the glass sample color tone yellow sugar, which correspond to the spectrum absorption of Fe3 that 450 nm and the co-op เนตสี hobbies in the system. CIE L * * * a B from UV - wisist Peebles spectrophotometric which (a *) is located between the 0.0401 - 0.1290 and private values (b *) is located between the 0.0821 to 53.4558 the density and the refractive index is similar. The increased when the amount of Fe2O3 increased both the density and refractive index. The density, the 2.4662 to 2.4918 g / cm3 and the refractive index in the range 2.4662 to 2.4918
