I used the same recipe I have used 100 times, but this time I chose to get full gel so I popped it into the over on 170, it has been in there for about 45 minutes and its puffed up, not a lot but enough to go about 1/4 inch above the fill lines! what I was wondering, is this normal? Will it go back? It never went to gel, it looked like the edges were going into trace and then now its just a puffin up
