Conclusion

Well our lab didn't go exactly as planned. We tried the expirement twice and the only difference was how severely we ruined the crucible. The borax powder melted to an extent but the liquid stopped the rest of the powder from being melted, with additional heat i think we may have been able to melt the majority of the borax powder without using to much of the hydrochloric acid. More heat may have helped but a specific amount of powder may have also made it a little easier to melt the borax and stop it from becoming the equivalent of cement on the inside of the crucible. In all i think our expirement failed because it could not be heated to a high enough tempature. This is the only major thing i could think of to change would be to apply more heat or possibly a larger bunsen burner to heat the crucible more evenly.
To use the words of Thomas Edison, We did not fail at making glass we just found one more way not to make glass.

Procedure

So i put this off till now anyways.............
The stuff we're gonna need for this expirement to work properly is a Crucible, Ringstand, Ring, Bunsen Burner, Triangle with pipe stem, esbestos mat, tongs, stirring rods, Borax, diluted hydrochloric acid, and Cobalt Nitrate

Procedure:
1) Filling the crucible about a third of the way with powdered borax and add 2 drops of water
2)Heat it until it melts together
3)Add a prefered color to the mixture and stir it with the stirring rod
4)pick up the crucible and pour it into the asbestos and allow it to cool
the glass may crack in this stage so we need to be extremely careful

There's Glass and there's ..................GLASS!!!!

We have chosen our project which is to make different types of glass and how hard they are. We plan to do this by creating the different types of glass in the lab and test them against each other during lab conditions
