Start with the shape that fits your loading arrangement. Kiln furniture works as a system: the plate, its support points and the space around the ceramic ware all influence the final specification.
02 / PERFORATED PROFILES
Perforated & Extruded Batts
Compare openings and extruded cross-sections with your load and kiln layout. Confirm the contact area and support span before choosing a profile.

Cordierite and Its Applications
Cordierite is a ceramic material associated with low thermal expansion. YUFENG’s products here use a cordierite-mullite material system, rather than describing every component as pure cordierite.
For a buyer, the useful question is how a particular grade and shape behave through the intended firing cycle. Thermal shock, expansion and strength should be considered together with the structure of the kiln setting.
Repeated heating and cooling
Thermal shock behavior matters when kiln furniture repeatedly changes temperature. Share the heating and cooling profile, including any rapid transitions.
Expansion and alignment
Expansion affects clearances and contact between components. Plan the space around the ware and the arrangement of adjacent supports.
Strength at operating temperature
A room-temperature strength figure cannot define the allowable load in a hot kiln. Evaluate the grade, working temperature, span and loading pattern together.
04 / From components to a kiln setting
Kiln Shelves and Furniture for Pottery and Ceramics
Pottery & Studio Ceramics
Begin with your kiln chamber, shelf layout and firing schedule. Include the weight and placement of the ware so that shelf thickness and support positions can be reviewed.
Tableware Production
Consider plate or bowl footprints, the number of levels and the loading arrangement. Keep support locations consistent with the selected batt and the space needed for the ware.
Sanitaryware Manufacturing
Large or shaped ware calls for careful attention to bearing areas, component alignment and the overall support structure. Share an existing setting drawing or photos when discussing replacements.

How to Select Cordierite Kiln Shelves and Supports
A size match is only the starting point. For replacement parts or a new setting, send the information below so the material and geometry can be assessed against the actual duty.
| Selection factor | What to provide | Why it matters |
|---|---|---|
| Firing temperature & hold | Peak and normal operating temperatures; time at temperature | Separates a brief peak from sustained operation. |
| Heating & cooling cycle | Cycle duration, ramp rates and cooling method | Defines the thermal changes experienced in service. |
| Load & support span | Ware weight, distribution and unsupported distances | Helps review batt thickness and support layout. |
| Dimensions & tolerances | Length, width, thickness and critical contact features | Supports fit, clearance and repeatable assembly. |
| Atmosphere & contact | Kiln atmosphere, ware material and coatings used | Enables a review of the material’s working environment. |
| Order & replacement scope | Part quantities, drawings, destination and existing failures | Clarifies the supply scope and the problems to address. |
06 / Compare the material grades
Material Grades and Technical Specifications
Use grade data to compare material characteristics alongside the loading and firing brief. The coefficient of thermal expansion includes its temperature interval; flexural strength includes the test temperature.
| Property / test condition | Unit | KFA | KFB | KFC |
|---|---|---|---|---|
| Bulk density | g/cm³ | 1.85 | 1.82 | 2.20 |
| Apparent porosity | % | 28 | 30 | 22 |
| Thermal expansion, 20–1000°C | 10⁻⁶ K⁻¹ | 2.6 | 2.2 | 3.2 |
| Flexural strength at 20°C | MPa | 14 | 11 | 11 |
| Flexural strength at 1250°C | MPa | 10 | 10 | 10 |
07 / Consider the alternatives
Cordierite or Silicon Carbide Kiln Furniture?
Compare materials around the same operating brief. The choice involves the complete setting, including section thickness, weight, load, atmosphere and the temperature profile.
Review the grade, shape and thermal cycle.
Explore cordierite-mullite kiln furniture where the intended firing duty matches the material and component design. Consider the available shelves, hollow profiles, props and saggars as a coordinated arrangement.
For an existing setting, include service photos and the reason for replacing parts, such as cracking or distortion.
Compare a different material system.
If your duty calls for another high-temperature support solution, review YUFENG’s silicon carbide kiln furniture range. Different SiC grades have different structures and service considerations.
Ask for an assessment using the same dimensions, load and firing conditions so the alternatives can be compared meaningfully.

Manufacturing and Quality Control
From formed shapes to a finished kiln setting, geometry needs as much attention as material selection. YUFENG supplies pressed and extruded cordierite-mullite components; the manufacturing route depends on the part profile.
Drawing & Dimension Review
Identify critical dimensions, openings, support faces and tolerances. Use a drawing revision to keep the proposed component and the order specification aligned.
Inspection Requirements
Agree on dimensional and appearance checks and the material information needed for the order. Request the relevant inspection records when discussing the supply scope.
Packaging & Supply Scope
Confirm piece counts, component identification and packing requirements for transport. Discuss how replacement supports and fittings should be grouped with the main parts.

Frequently Asked Questions
What is cordierite kiln furniture used for?
It supports, positions or contains products during firing. Shelves and batts provide loading surfaces, props establish the spacing between levels, and saggars contain a load. Select the combination around the ware and the kiln layout.
What is the difference between cordierite and cordierite-mullite kiln furniture?
Cordierite names a ceramic material, while cordierite-mullite describes a material system combining these phases. The YUFENG products featured here are cordierite-mullite. Ask for the grade designation when comparing technical data.
What temperature can cordierite kiln shelves withstand?
The suitable operating temperature depends on the material grade and component design, as well as the load, hold time and atmosphere. Send your normal and peak temperatures with the firing cycle to obtain a recommendation for the intended service.
How do I choose shelf thickness and support spacing?
Provide the shelf dimensions, supported weight, load distribution and proposed contact points. Thickness and span need to be reviewed together with temperature; selecting by thickness alone does not establish the allowable load.
Should I choose cordierite or silicon carbide kiln shelves?
Compare the available grades against your operating temperature, thermal cycle, load, support structure and atmosphere. A useful comparison uses the same duty and component dimensions, rather than assuming one material suits every kiln.
What information is needed for a quotation?
Send the part shape, dimensions or drawing, quantity, firing conditions, loading details and delivery destination. For replacements, include photos of the existing parts and their location in the kiln setting. State any inspection and packaging requirements.
