I have a new Paragon Electric Kiln with a digital controler. I program
it for cone #5 with a 10 minute hold for my glazing. What slower
cooling rate than the normal cool down should I use to allow crystal
glazes to work and help keep Greenware from cracking?

I don't know what kind of controller you have, but it should provide a function
that will slow down cooling. The Mastering Cone 6 Glaze Book specifies some
good rates of cooling that bring out the crystals in the recipes they have. The
elements actually come back on to do this. You'll need to find out what works
for your glazes and how to program your controller.
