Claim 1

A METHOD FOR THE MANUFACTURE OF ACOUSTIC FIREPROOF TILE WHICH CONSISTS, FIRST IN PREPARING A PLASTIC MIX COMPRISING 13 TO 30 PARTS IF DIATOMECEOUS EARTH, 7 TO 30 PARTS OF ACRBONACEOUS COMBUSTIBLE MATERIAL CAPABLE OF ABSORBING A RELATIVELY LARGE AMOUNT OF WATER, 11/4 TO 21/2 PARTS OF GLAZING MATERIAL IN DISPERSION AND HAVING A LOWER FLUXING TEMPERATURE THAN THE DIATOMACEOUS EARTH, 10 TO 70 PARTS OF WATER TO OBTAIN A MIX WITH AS MUCH WATER AS IT WILL HOLD BUT STILL RETAIN A GIVEN SHAPE, NEXT FORMING OR SHAPING A TILE CORE FROM THE MIX, AND FINALLY, SUBJECTING THE CORE TO A BAKING TEMPERATURE FROM 17000* TO 2300*F. BETWEEN 11/2 TO 31/2 HOURSE WHEREBY STEAM FROM THE WATER HELD IN THE MIX PROVIDES PORES EXTENDING FROM THE INNER PART OF THE CORE THROUGH THE SURFACE THEREOF, AND IN CONJUNCTION WITH THE GASES FROM THE CARBONACEOUS MATERIAL THE WALLS OF THE PORES ARE GIVEN RIGIDITY TO MAINTAIN THE SAME, AND THE GLAZING MATERIAL IN THE MIX IS DEPOSITED THERETHROUGH ON THE SURFACE OF THE CORE, WHICH IS FLUXED AND THUS FORMING A GLAZE FOR THE CORE WITH PORES IN REGISTER WITH PORES OF THE CORE, SAID CORE HAVING A SOFT-LIKE AND CRUMBLY CENTRAL AREA WITH HIGH SOUND ABSORPTION CAPACITY AND HIGH FIRE PROTECTION PROPERTIES.
