what started out a frozen pipe has spurned another issue...

last year I had a frozen pipe in my downstairs bathroom. I put a torch to it for about 30 min and the water broke through. today I attempted the same thing. This time after about 30 min the shutoff valve melted off. I didn't have the flame directly there but apparently it got hot enough to melt. The handle came off and about an inch of oozing plastic came out of the hole vacated by the valve. I shut the water supply off. so...what is my next move? Id like to be able to shut the water off from the toilet so I can turn the main back on which feeds the sink and shower. Can I just replace the shut off valve?

Why not just replace the valve?
Unless your soldering you should have using a heat gun or hair dryer.

Yes, replace the shut off valve.

Ive got replacement valve. However there is still the matter of the frozen pipe. About1 3/4 inch of pipe is exposed through wall. Can apply a torch or other source of heat directly to that to try and break through?

After destroying the valve I am surprised you haven't learned your lesson about using a torch to thaw a pipe. You've already been told nicely what you should be using.

You risk burning your house down thawing pipes with a torch.

I would treat replacing the valve and thawing your pipes as separate issues. Use the torch to solder on the replacement valve.

Do you know where your frozen pipe runs? I'm guessing it's a toilet line since you didn't mention a cabinet and I assume it's on an exterior wall. Can you access the line from below in a basement or crawl space?
