## Questions & Answers

**Q: Best glue to hang 8lb glass on a window**
A: This is ABSOLUTELY not the product for that. This is used to glue glass pieces together so they stay connected while heating in a kiln. There is no glue to glue glass to a window. You may be able to visit a home hardware store and get a silicone caulking but I'm not really sure what your project is so I cannot make a recommendation. Do NOT use this to attach glass to glass in any type of application besides glass fusing. 

If you're talking about a stained glass panel, it should be framed and attached to wall (stud) with proper hanging materials. Glass that heavy should never be hung by attaching it to a window.

**Q: What's the difference between the two glastac products?**
A: Both products are water soluable, burn out cleanly in the kiln and tack glass pieces together prior to placement in the kiln.  The original pink has a thinner consistency and it is slower to dry which can be useful when adjustments are needed during design.  The gel is thicker, holds shape better and has a stronger, more immediate bond useful in situations when there is a need to move the project without waiting for the product to dry.

**Q: Would this work for my Pate de Verre?**
A: Yes. It's thicker than the Ed Hoy Hotline version, but it will work.
