I have a 56 amp, 208 volt ceramic kiln that I need to hook up to residential service. It's basically an overgrown toaster oven. Is this even possible and if so what effect will it have on the equipment?

In what country was the kiln made and where will you be hooking it up?

Most kiln heating elements are rated to handle 208, 230, 240, and some even up to 277 volts, will operate fine on either voltage.
Need to check the nameplate rating.
If the 208 volt element is only rated 208 volts, the element will operate at a higher temp, but, will burn out the element quicker. If there is any damage done, you will be responsible.
Best to check with the manufacturer's website.

Without consulting the manufacturer, I'd guess it is resistance heat.
It will draw more current, heat up faster, and the thermostat will turn it off sooner.
TKRussel is also correct, the element may burn out sooner.

Thanks for the imput. Turns out all of NYC residential is at 208. FYI they make kilns up to 480 volts for industrial applications.

So you are plugging a 208 volt kiln into a singe phase 208 receptacle, so no issue after all.
