We offer the standard caveat: All repair work is accepted on a best effort basis with no guarantee or warranty of a successful repair. Your glassware may be further damaged or destroyed in the repair attempt. We do not accept liability of any kind for damage to the glass or the loss of the object. You will not be charged for any of our efforts, materials, or time if the repair attempt fails - it is in our interest to be successful!
You can see some of these successes here.
