I am new to fusing and am having a hard time getting two pieces to fuse
all the way across. It usually fuses at the top and bottom and leaves a
gap in the middle. Do the pieces have to be perfectly touching to fuse?
I am taking it to 1450 degrees, do I need to go higher?

You need to read the tutorial on this website: http://www.warmglass.com/Basic.htm

Are you using only 1 layer of glass?

Glass naturally wants to be 1/4" thick - so if there is only one 1/8" layer (or gaps in the top layer) it will "pull" in and try to become 1/4" thick.

Most people commonly use a solid piece of glass for the bottom layer and then put the design pieces on top. Yes, you need to cut precisely and have the edges touching to get the edges to fuse together.

Hope this helps.

Thanks,
I did not realize that glass wanted to be 1/4 inch. I will try again using
two layers. So far I have some interesting sun catchers so all is not lost.

Thanks again,
Finally got something to fuse like I wanted. From now on its two pieces of glass stacked.

and some people put the design elements on the bottom with a panel of clear on top, like this;


That way it gives depth and a shiney smooth top surface.

Cut the top (clear layer) big enough to overlap the base. The amount of overlap is the same as the thickness of the base.

Just another option for you to consider.
