The base body includes a space extending from the connection portion to a lower surface of the base body. The space includes a first space and a second space. The first space contacts with the connection portion. The second space connects the first space and an outer side of the lower surface of the base body, and is smaller than the first space in a planar perspective of the lower surface of the base body.

A method for heating ware in a kiln. The ware space of the kiln includes a plurality of temperature control zones oriented in a first direction, and a plurality of temperature control zones oriented in a second direction. The method includes heating the ware space in a first heating stage, a second heating stage, and a third heating stage. At least one of the following conditions is satisfied: (i) in one of the heating stages, a temperature control zone oriented in the first direction has a setpoint temperature that is different from a setpoint temperature of one other temperature control zone oriented in the first direction; and (ii) in one of the heating stages, one temperature control zone oriented in the second direction has a setpoint temperature that is different from a set point temperature of one other temperature control zone oriented in the second direction, wherein the first direction is a vertical direction and the second direction is a horizontal direction.

A method for drying at least one unfired columnar honeycomb formed body comprising a raw material composition containing at least one raw material of ceramics, water and at least one heat-gelling binder, and cells defined by partition walls comprising flow paths from a first end surface to a second end surface. The method comprising drying the honeycomb formed body by passing hot gas satisfying 0.8≤T2/T1≤3.3, where T1 represents a gelation temperature of the binder (° C.) and T2 represents a wet-bulb temperature of the hot gas (° C.) through the flow paths from the first end surface and out the second end surface, while surrounding the honeycomb formed body with a correction mold to correct the shape of the honeycomb formed body during drying.

A method for forming a multi-layer blank of a ceramic material including the steps of: providing a mold that includes at least one side wall surrounding a lower press plunger to form a cavity therebetween, wherein the lower press plunger has a movable pin; filling into the mold a first ceramic material; extending the movable pin from an upper surface of the lower press plunger and into the cavity; pressing a first upper press plunger against the first ceramic material so that a first open cavity is formed while at least a portion of the first upper press plunger is in contact with the movable pin to maintain the through-hole through the first layer; filling into the mold a second ceramic material of a different composition; extending the movable pin from an upper surface of the first layer and into the first open cavity; and pressing a second upper press plunger against the second layer so that a second open cavity is formed in communication with the through-hole that extends through the first and second layers to form the blank.

A method for heating ware in a kiln. The ware space of the kiln includes a plurality of temperature control zones oriented in a first direction, and a plurality of temperature control zones oriented in a second direction. The method includes heating the ware space in a first heating stage, a second heating stage, and a third heating stage. At least one of the following conditions is satisfied: (i) in one of the heating stages, a temperature control zone oriented in the first direction has a setpoint temperature that is different from a setpoint temperature of one other temperature control zone oriented in the first direction; and (ii) in one of the heating stages, one temperature control zone oriented in the second direction has a setpoint temperature that is different from a setpoint temperature of one other temperature control zone oriented in the second direction.

The invention relates to a blank from a ceramic material, wherein at least two layers of ceramic material of different compositions are filled into a die layer-by-layer and after filling of the layers they are then pressed and sintered, wherein after filling of a first layer this is structured on its surface in such a way that the first layer, viewed across its surface, differs in its height from region to region, and then a layer with a composition that differs from the first layer is filled as a second layer into the mold.
