Metal heat shield works fine, but still gets hot and transfers lots  
of heat to everything around. Ceramic is a very good heat insulator  
(space shuttle). That's why they line the inside of kilns with  
ceramic blocks. When on the inside they could be red hot for hours,  
you can put your hand on the outside. I'm already thinking how to  
make heat shield from this material.
