We bake the converted oxide layers for 55 minutes at about 90-105C. I 
     don't know if anything bad will happen if the baking is less than 
     this, but more baking than this means danger of re-oxidising the 
     reduced oxide, risking the occurance of pink ring after SES.
     
     By the way, can anybody tell me what is the other causes of pink ring, 
     beside oxide?

     Hello,
        Does baking inner layers after oxide conversion, (prior to lay up) 
     help in any way? How does it help? How can it hurt? Are some shops 
     doing this? 
     Thank you,
     Rich
