How could I repair my antique glass pitcher?

I have a beautiful 11/2 to 2 quart thin glass pitcher that belonged to my grandmother and maybe her mother. It is clear glass with iridiscent mauve borders top and bottom. The body of the pitcher is sandblasted to apear opaque and has flowers painted on it. There is a raised row of tiny white dots along the edge of the sandblasted area. My mother warned me not to use really hot water to wash it and I rejected her advise and poured boiling water in it to scald and sterilize it. The glass cracked in an irregular U-shape from about 2-3 inches from the bottom, down and under the pitcher and part way up the other side. It appears that my mother attempted to repair it with some kind of glue along the crack. If there is a way to repair it, I would like to pass it on to the next generation in usable condition. I did this over 43 years ago when I arrogantly "knew" my mother was wrong. It has been on my conscience ever since.
The pitcher and the matching drinking glasses have no identification on them.
