What is the use of boric oxide to improve the quality of glass?
Borosilicate glass is resistant to higher temperatures; this glass is used for chemical labware.
What compound is boric oxide?
Boron oxide is used as a fluxing agent in the production of glass. For more see related links below.
How to make zinc borate?
Heat Zinc oxide and Boric acid (Boric powder) in water.
What is cobalt glass?
cobalt glass is glass containing cobalt oxide or cobaltous oxide as a colouring agent. These oxides give the glass a blue colouring.
Is boron oxide acidic or basic?
Boron oxide, B2O3, is acidic. It reacts slowly with water to form boric acid. When fused, (molten) it reacts readily with metal oxides to form borates.
Why boron oxide is added while preparing ordinary glass?

What distinguishes lead crystal barware from ordinary glass?
Crystal glass is made differently with a different chemical composition (lead oxide is added). It is then cut either by hand or by machine to create facets and/or designs.
What is the name for this formula B2O3?
Boric Oxide.
How to make zinc borate?
Heat Zinc oxide and Boric acid (Boric powder) in water.
What is the benefit of using boron oxide over boric acid in lining of induction furnace?
As per my knowledge Boric acid dissociates into Boron oxide by escape of water molecules from boric acid near to 300 deg centrigrade; hence bonding may be weakened. But in case of Boron oxide use, there is no dissociation of Boron oxide.
What makes pyrex glass heat resistants?
PYREX (TM) is a borosilicate glass with a very low coefficient of thermal expansion (3.3 x 10−6/K - about one-third that of ordinary glass). The boron (or boric oxide) in the matrix apparently helps moderate the effect of changes in temperature so that even when it undergoes large changes in temperature, it doesn't expand or contract as much as normal silicate glass; normal glass will crack when exposed to big temperature changes. In this respect it has good heat resistance. It is also very chemically stable with temperature - again a "heat resistant" characteristic. Finally, it has a high melting point (~820 °C or 1,510 °F) so it tolerates oven temperatures quite well.
What is the chemical formula of boric oxide If B203 is listed as Barium Oxide which I thought tow BaO then what is Boric Oxide which I thought was B203?

What mass of boric oxide is formed from the decomposition of 10g BOH3?
5g of boric oxide because BOH3 is twice as big as Boric oxide so half as much as formed. it is also relative to the atomic mass of C12. Taken from text book by Dr. Rory Moloney and Dr. Fran Molloy. Hope this helps you in your quest from chemistry knowledge.
What is the principal mineral used in making glass?
Glass is manufactured primarily from the mineral quartz (SiO2) which is what sand is made from. However small amounts of other minerals are added to the sand to make the process easier. These minerals are:- sodium carbonate (Na2CO3) lime (calcium oxide (CaO) magnesium oxide (MgO) aluminum oxide (Al2O3) There are also other minerals which are added to make specialised glasses. e.g. Pyrex glass is made from sand and boron oxide.
Si O2 is the formula for this mineral?
Heating a mixture of quartz (SiO2) and calcium oxide (CaO) - also known as lime, makes ordinary glass.
