Old Potters Mid High Fire White Stoneware Clay

Old Potters White Stoneware Clay is designed for a broad range of pottery techniques, including wheel throwing, hand building, and sculpting. The clay fires at cone 5 through cone 10, offering flexibility for both beginner and advanced potters. Its low iron content helps minimize glaze interaction, yielding cleaner glaze surfaces and sharper details. The 10-pound bag provides ample material for multiple projects, making it a practical option for studios testing cone 6 performance.
Its plasticity is described as workable across various methods, from pinch pots to slabs and coils. This versatility makes it suitable for artists who experiment with different forms. The clay’s reliability across firing ranges ensures predictable results, a key factor for planning kiln loads and glaze schedules. While it targets a broad firing window, cone 6 results are typically stable, with good detail and minimal warping when properly wedged and conditioned.
Deouss Mid High Fire White Stoneware Clay (5 lb)

Deouss offers a mid-range white stoneware clay with a firing range around cone 5 to cone 7, making it suitable for wheel throwing, hand building, and sculpting. This 5-pound bag is ideal for small to medium projects and glaze testing. It provides sufficient plasticity for intricate forms and can be fired successfully at cone 6 with appropriate glaze compatibility. The product line emphasizes broad glaze possibilities, allowing artists to explore finishes from matte to glossy high-fire glazes.
Versatility is a key benefit, with use cases spanning tiles, slabs, coils, pinch pots, beads, and figurines. The clay’s texture supports detailed work while maintaining workable consistency during shaping. For studios that pace production, the 5-pound size can supplement larger bags, enabling workflow planning without committing to larger stock until glaze results across cone 6 are confirmed.
Deouss Mid High Fire White Stoneware Clay (10 lb)

This 10-pound version mirrors the 5-pound option with a cone 5-7 firing window, offering more material for larger projects or extended glaze testing. It is well-suited for wheel throwing, hand building, and sculpting, with the same emphasis on broad glaze possibilities. The increased bag size can improve production efficiency for studios, allowing longer runs between reorders while preserving consistent performance across cones 5 through 7 and toward cone 6 with proper firing profiles.
The Deouss line is noted for non-toxic, user-friendly characteristics, aligning with classroom safety requirements. The clay body tends to remain plastic over longer sessions, which helps maintain form during complex builds, and it responds predictably to standard cone 6 glaze programs once fully matured in the kiln.
50lb Best Mix- BMX Mid Fire Cone 6 Pottery Clay

The BMX Mid Fire is designed as a smooth white clay suitable for both wheel throwing and hand building, with a large 50-pound bag that supports larger projects and frequent firing tests. It’s non-toxic and classroom-friendly, making it a practical choice for schools and studios where multiple users share a single bag. The cone 6 firing window aligns with standard glaze schedules, enabling predictable results for a wide range of glazes and textures.
In terms of workability, this clay maintains a balanced plasticity that accommodates pinch, coil, slab, and throw forms. The color is typically bright white when fired, providing a clean canvas for glaze experiments. The large bag size is advantageous for ongoing production runs, though storage considerations and moisture control are essential to maintain plasticity over time.

This 25-pound stoneware clay from Rocky Mountain Clay offers a speckled buff appearance, ideal for rustic or handmade aesthetics. It is designed for hand building and wheel throwing with a cone 6 firing range, delivering reliable shrinkage, texture, and glaze compatibility. The smoother de-airing process helps reduce pinholing and warping during firing, while maintaining workable plasticity for wheel work and slab construction.
For studios prioritizing load efficiency, the 25-pound size balances price-per-bag with practical handling. The clay suits both beginners advancing to intermediate levels and experienced potters seeking consistent results in a cone 6 program. Its balance of plasticity, control, and finish quality makes it a strong all-around choice for a variety of forms and glaze outcomes.
Buying Guide: Cone 6 Stoneware Clay Buyers’ Considerations
- Firing range compatibility: Look for clays labeled cone 5-7 or cone 5-10 to accommodate cone 6 glaze schedules without sacrificing detail or surface quality.
- Plasticity and workability: Choose clays described as highly plastic for wheel throwing and hand building, especially if you plan pinch pots, coils, and slabs.
- Weight and bag size: Smaller bags are convenient for testing; larger bags (25–50 lb) suit ongoing production but require moisture control and storage space.
- Glaze compatibility: Consider clays with low iron content or described glaze-friendly behavior to minimize surface reactions and color shifts at cone 6.
- Texture and finish: Speckled, Buff, or white surfaces affect glaze choices and final aesthetics; align with your preferred glaze palette.
- Safety and classroom use: Non-toxic formulations and clear handling guidance are important for shared spaces and teaching environments.
- Storage and moisture management: Proper sealing of bags prevents drying and cracking, preserving plasticity over time.
- Cost vs. value: Compare price-per-pound and anticipated yield; large bags may reduce per-unit costs but require more storage and care.
