It really depends on the type of glass. Glass is made from silica, which is the common ingredient in all glasses. From there on everything else varies. One simple thing to remember is that glasses are usually named for their fluxes (with a few exceptions). To get the silica to melt at a lower temperature, a flux is added. Some examples are:
Soda-Lime glass (very commonly used for drinking glasses, windows, etc) has lime and sodium carbonate as flux.
Borosilicate glass contains Borax or Boric acid as a flux
Lead Crystal is a glass using lead as its flux. The lead increases the refractive index, which when cut makes the glass sparkle. Hence it is used a lot in tableware. It was developed expecially for this by Ravenscroft.
Flint glass has flint as its flux
and so-on.
In addition to this glass also contains stabilising agents and clarifying agents.
Coloured glass contains in addition to the above various metal oxides as colouring agents.
for example
cobaltous/cobalt oxide makes blue
selenium or copper or gold oxide can make reds
chromium oxide makes green
tin oxide makes white
silver oxide makes transparent yellows
cadmium can make opaque yellow, orange and red amongst others
some glasses contain combinations of these
The raw mixture of the chemicals glass is made of is called "batch". Often chemicals present in the batch are not present in the melt, as some chemicals are used as catalysts to produce certain reactions at certain temperatures. A chemical change occurs and the catalyst is burned off or changed from one form to another.
hope this helps somewhat
mixed matireals
dogees
medieval castlezs where generaly more complex and made of alot weaker matireals medieval castlezs where generaly more complex and made of alot weaker matireals
HELPFUL HINT! Hint:Its One Of The 5 Matireals. Sand, Rock, Snow, And Dirt. Look For The Item That Uses Them ALL! Then Type It! (this is from someone who's found out!)
something like fabric (you can touch it and its soft). or you can use glue tape and paper to make something with those matireals.
Pyrex is the trade name of a Corning low thermal expansion glass. All Pyrex is glass, not all glass is Pyrex.
No. Glass is not an electrolyte at all.
bullseye glass offers glass for all purposes. they can match types of glass against other glass for compatibility. they offer education in all types of glass art
Glass is a ceramics but ceramics is not a glass. it is like saying all bugs are insects but all insects are not bugs... get it
No. Glass is not an electrolyte at all.
Production and materials management is very important in the process of manufacturing. This will ensure that there are no wastages and thereby increasing productivity and the returns on investment.
All new vehicles have the vehicle identification number etched into the glass. The vehicle ID number etched into the glass was mandated for all vehicles beginning in 2010.
