How can you tell if glass is soda-lime?

Eyeball It. If you have a dish at home that you want to test you can also try just looking at the hue. If you look at the edge of a dish and it is made out of soda-lime glass it will be a blueish-green hue. If the glass is Borosilicate then you should not see any color.

What is Type 3 soda-lime glass?

Type III soda-lime glass is a silica glass containing alkali metal oxides. Soda-lime glass exhibits moderate chemical resistance and moderate hydrolytic (water) resistance. Soda-lime glass is inexpensive, chemically stable, and ideal for recycling as the glass can be re-melted and re-formed multiple times.

Is BK7 a borosilicate glass?

Bk7 is a barium borosilicate glass known for its high transmission and clean, clear appearance. These characteristics make Borofloat more costly than float glass, but borosilicates retain shape and handle thermal shock better than other, less expensive glasses.

Is BK7 birefringent?

Figure 4.17 A block of N-BK7 shows stress birefringence reduction due to cutting it down to smaller-sized pieces.

What kind of sheet glass is B 270?

When other glass materials begin to change their color, B 270 ® stays white and clear. B 270 ® is available as drawn glass, fire-polished sheet glass, or unpolished raw glass ingots. B 270 ® as sheet-glass exists at many standard thicknesses.

What kind of transmission material is Schott B270?

Range / Description: Schott B270 for 320-2600nm transmission Material / Specification: TSG-B270 B 270 Superwite B 270 Superwite is a clear high transmission crown glass (modified soda-lime glass) available in form of sheets, optical rods, profiled rods, strips and chain moulded rod.

What makes B 270 crown glass crystal clear?

The SCHOTT glass has a colorless crystal-clear appearance. It is very stable to the solarization effects that usually occur when a material continuously is exposed to the sun or UV light. When other glass materials begin to change their color, B 270 ® stays white and clear.
