Yeah, I'm too impatient for the hair dryer routine. I use a high velocity
paint stripper gun (most any hardware, e.g., Home Depot, Lowes). They get
to ~1000 degrees with cfms of 20 - 25 ... blows a whole lot of very hot air=
!
Need to keep your body parts (and other combustibles) away from the direct
air stream and/or the heat shield of the gun. Bosch makes a good one for
about $90 -$100.

A paint removal heat gun from the tool aisle will generate a more

Best Not to do this to porcelain. It creates a skin on the surface that
tends to crack at any time. I use a metal rib to remove any slip on the
surface to keep the body from absorbing water.

I use an electric paint stripper and sometimes a torch.
You just have to move the stripper/torch and heat evenly. Just
takes practice. It works with porcelain too. The clay always moves
toward uniformed moisture., pulling it from inside to the surface, so
no "skin" can stay that way long.
