摘要：
A method is disclosed of dehydrating a thin water based ceramic slurry coating on a foam pattern assembly having hidden internal surfaces. The method comprises sequentially subjecting the coated assembly to a first warm air flow at a sufficient temperature and time to dehydrate and remove 60-80% of the water of the coating, and secondly subjecting the dehydrated coating assembly to low level microwave energy to substantially remove the remainder of the water in all of the coating, the dehydrated coating being devoid of bubbles or cracking.
