Given the EÂ° values for two half reactions, you can easily predict the potential difference of the corresponding cell: simply add the reduction potential of the reduction half-cell to the negative of the reduction potential (that is, to the oxidation potential) of the oxidation reaction.
How to Melt Glass With a Torch. Glass melting has a long history, going back to approximately 3000 BC. In these early times, glass was melted to decorate vases. Glass is made up of silica, sodium carbonate and calcium carbonate. Most glass melts at 1400 to 1600 degrees Farenheit. Nevertheless, there are specialized glasses that will melt at as low as 900 degrees.
This is such a great site! You all are so talented with glass! I've surfed the site and read many of the tutorials and such, but cannot seem to find what I'm looking for. :crying: In brief, what I am seeking is a torch that will allow me to. (pardon the lack of proper wording) melt the edges of. a glass bottle cut on a tile saw. The torch will not be used for. bead making, so perhaps a standard torch from a hardware. store could be used. The melt does not have to be perfect at all, I simply want. to smooth down the sharpness of the freshly cut edges. Another example would be melting a shard of glass just enough. to smooth the sharpness.
