FIELD: process engineering.
SUBSTANCE: proposed method comprises layer-by-layer application of refractory suspension on pattern and coating by granular material. Starting from second layer to granular material added are oxygen-containing substance in amount of 5-10 wt % and boric acid in amount of 2-3 wt %. Patterns are rendered by hot water for shells to be calcinated.
EFFECT: higher efficiency and quality.
