What happens if you repeatedly melt glass?

If you have glass and you melt it, then allow it to cool and harden, then melt it again and repeat a few times, will the glass become brittle? What change will happen to the glass?

Glass is already tremendously brittle.

But to respond to the substance of your question: glass doesn't have a memory. It doesn't remember that it's been melted 50 times before in the last 24 hours instead of 1 time. So the parameters that affect the properties of glass are simply those of the most recent melt/solidification cycle.
