Common questions
What types of steel can I heat treat in the KM18?
The 2350°F maximum temperature handles all common blade steels including 1095, 5160, 52100, O1, A2, D2, and high-alloy stainless steels like 440C and AEB-L. The temperature range covers both hardening (typically 1450-2100°F depending on alloy) and tempering cycles (300-1000°F). For high-speed steels and some exotic alloys requiring temperatures above 2200°F, verify your specific steel's austenitizing temperature falls within the oven's range. The gas inlet ports allow connection of argon or nitrogen atmosphere systems to prevent oxidation during hardening of reactive steels.
Do I need to add a gas atmosphere system, or can I heat treat in air?
Many carbon steels can be successfully heat treated in air atmosphere for forged blades that will be ground post-hardening, though some surface scaling and decarburization will occur. For stock removal blades with finished grinds, stainless steels, or when minimal scale is critical, connecting an inert gas system (argon or nitrogen) to the inlet ports creates a protective atmosphere that prevents oxidation and decarburization. The inlet ports come standard on the KM18; the external gas delivery system and regulators are purchased separately based on your quality requirements and production volume.
What controller comes standard, and can I program custom heat treating cycles?
The KM18 includes a digital programmable controller with basic ramp-hold-cool programming suitable for standard hardening and tempering cycles. You can set target temperatures, ramp rates, and soak times for typical two-step heat treating (austenitizing followed by tempering). For more complex metallurgy requiring multi-step thermal cycles, precise ramp control, or data logging for quality documentation, the Genesis touchscreen upgrade provides advanced programming with up to 250 stored profiles and USB export capability.
How does the double barrel design compare to single chamber knife ovens?
The double barrel configuration essentially gives you two independent 18-inch ovens in a single unit, allowing you to run different heat treating cycles simultaneously—for example, hardening one batch while tempering another, or processing two different steel types at their respective austenitizing temperatures. This doubles production capacity compared to the single-barrel KM18S while using less floor space and often lower per-piece energy cost than running two separate ovens. Each chamber operates independently with separate heating elements and temperature control.
Is this oven backed by a manufacturer warranty when purchased through Peach State Pottery?
Yes. The KM18 includes Paragon's one-year limited warranty covering defects in materials and workmanship when purchased through authorized dealers like Peach State Pottery. You must register your oven within 30 days of delivery to activate warranty coverage. Purchasing through unauthorized resellers or used markets typically voids manufacturer warranty. Peach State Pottery can assist with warranty registration and any service needs during your warranty period.
Not sure if the KM18 double barrel is the right heat treating oven for your production needs? Our kiln specialists can discuss your blade lengths, production volume, steel types, and atmosphere requirements to recommend the best Paragon knife oven configuration.

Shipping/Returns

Paragon Kilns Shipping & Returns

At Peach State Pottery, we want your Paragon kiln delivery experience to be as smooth and stress-free as possible. Paragon ships thousands of units each year, with only a small percentage experiencing freight issues. Understanding how freight delivery works will help ensure your kiln arrives safely and that you are prepared when it arrives.

Because many Paragon kilns are heavy, fragile, and shipped by freight carrier, it is important to understand the delivery process before your order arrives.

Shipping & Delivery

Small Paragon Kilns

Smaller Paragon kilns are generally shipped by FedEx or UPS, making delivery simple and convenient.

For your protection, Paragon requires a signature upon delivery. This gives you a moment to inspect the package before accepting it and helps ensure any visible issues are addressed right away.

Medium & Large Paragon Kilns

Medium and large Paragon kilns are delivered by commercial freight to the curbside or front of your driveway.

Standard freight delivery does not include:

  • Uncrating
  • Carrying the kiln inside
  • Placement in your studio, garage, home, or workspace
  • Setup or installation

Residential deliveries usually require liftgate service, which must be requested at the time of order. If liftgate service is not included, the customer will need access to a forklift, loading dock, or similar equipment to unload the pallet from the truck.

Access & Delivery Challenges

Please contact us before ordering if your delivery location has possible access issues, such as:

  • Gravel or dirt roads
  • Steep driveways
  • Narrow streets
  • Low-hanging trees or low clearances
  • Limited truck access
  • Rural or hard-to-reach delivery locations

Depending on your situation, possible options may include meeting the truck nearby, picking up the kiln at the freight terminal, or requesting delivery with a smaller box truck when available.

Unloading Your Kiln

Once your kiln arrives, the customer is responsible for moving the kiln from the delivery point to its final location unless a separate moving or installation service has been arranged.

Hire a Local Moving or Package-Handling Service

Many customers choose to hire a local moving or package-handling service experienced with heavy equipment. These teams can help off-load the crate and move the kiln into your workspace for an additional fee.

This option is especially helpful for larger kilns, tight spaces, or customers who do not have the proper unloading equipment available.

Unload the Kiln Yourself

If you prefer to handle unloading yourself, make sure you have the proper equipment and enough help available. Depending on the kiln size and weight, this may require a pallet jack, dolly, forklift, loading dock, or similar equipment.

Planning ahead before delivery helps make the unloading process safer and smoother.

Inspecting Your Shipment

All Paragon shipments are FOB origin, meaning ownership transfers when the kiln leaves Paragon’s facility. Inspection upon delivery is essential.

Please inspect your shipment carefully before signing for delivery.

If There Is Minor Visible Damage

  • Note the damage on the delivery paperwork before signing.
  • Take clear photos of the packaging and any visible damage.
  • Accept the shipment if the damage appears minor.
  • Inspect the kiln immediately after unpacking.
  • Contact Peach State Pottery as soon as possible.

If There Is Severe Visible Damage

  • Refuse the shipment if the damage appears severe.
  • Take detailed photos before refusal.
  • Contact Peach State Pottery right away.

If You Discover Concealed Damage

Concealed damage is damage discovered after the kiln has been unpacked.

  • Notify the carrier and Peach State Pottery as soon as possible.
  • Keep all packaging materials.
  • Take detailed photos and/or video.
  • Report the issue within 5 days of delivery.

Photo & Video Documentation

Before opening the crate or box, take clear photos or video of the packaging from all sides.

Continue documenting as you unpack, especially if you notice broken crate boards, crushed packaging, holes in the box, visible impact marks, or any visible damage to the kiln or accessories.

This documentation is essential to help support a freight claim if damage is discovered.

If a claim is needed, documentation may include the carrier’s claim form, bill of lading, Paragon invoice, freight bill, inspection report, photos, videos, and repair estimate.

Many carbon steels can be successfully heat treated in air atmosphere for forged blades that will be ground post-hardening, though some surface scaling and decarburization will occur. For stock removal blades with finished grinds, stainless steels, or when minimal scale is critical, connecting an inert gas system (argon or nitrogen) to the inlet ports creates a protective atmosphere that prevents oxidation and decarburization. The inlet ports come standard on the KM18; the external gas delivery system and regulators are purchased separately based on your quality requirements and production volume. What controller comes standard, and can I program custom heat treating cycles? The KM18 includes a digital programmable controller with basic ramp-hold-cool programming suitable for standard hardening and tempering cycles. You can set target temperatures, ramp rates, and soak times for typical two-step heat treating (austenitizing followed by tempering). For more complex metallurgy requiring multi-step thermal cycles, precise ramp control, or data logging for quality documentation, the Genesis touchscreen upgrade provides advanced programming with up to 250 stored profiles and USB export capability. How does the double barrel design compare to single chamber knife ovens? The double barrel configuration essentially gives you two independent 18-inch ovens in a single unit, allowing you to run different heat treating cycles simultaneously—for example, hardening one batch while tempering another, or processing two different steel types at their respective austenitizing temperatures. This doubles production capacity compared to the single-barrel KM18S while using less floor space and often lower per-piece energy cost than running two separate ovens. Each chamber operates independently with separate heating elements and temperature control. Is this oven backed by a manufacturer warranty when purchased through Peach State Pottery? Yes. The KM18 includes Paragon's one-year limited warranty covering defects in materials and workmanship when purchased through authorized dealers like Peach State Pottery. You must register your oven within 30 days of delivery to activate warranty coverage. Purchasing through unauthorized resellers or used markets typically voids manufacturer warranty. Peach State Pottery can assist with warranty registration and any service needs during your warranty period.

Shipping/Returns

Paragon Kilns Shipping & Returns

At Peach State Pottery, we want your Paragon kiln delivery experience to be as smooth and stress-free as possible. Paragon ships thousands of units each year, with only a small percentage experiencing freight issues. Understanding how freight delivery works will help ensure your kiln arrives safely and that you are prepared when it arrives.

Because many Paragon kilns are heavy, fragile, and shipped by freight carrier, it is important to understand the delivery process before your order arrives.

Shipping & Delivery

Small Paragon Kilns

Smaller Paragon kilns are generally shipped by FedEx or UPS, making delivery simple and convenient.

For your protection, Paragon requires a signature upon delivery. This gives you a moment to inspect the package before accepting it and helps ensure any visible issues are addressed right away.

Medium & Large Paragon Kilns

Medium and large Paragon kilns are delivered by commercial freight to the curbside or front of your driveway.

Standard freight delivery does not include:

  • Uncrating
  • Carrying the kiln inside
  • Placement in your studio, garage, home, or workspace
  • Setup or installation

Residential deliveries usually require liftgate service, which must be requested at the time of order. If liftgate service is not included, the customer will need access to a forklift, loading dock, or similar equipment to unload the pallet from the truck.

Access & Delivery Challenges

Please contact us before ordering if your delivery location has possible access issues, such as:

  • Gravel or dirt roads
  • Steep driveways
  • Narrow streets
  • Low-hanging trees or low clearances
  • Limited truck access
  • Rural or hard-to-reach delivery locations

Depending on your situation, possible options may include meeting the truck nearby, picking up the kiln at the freight terminal, or requesting delivery with a smaller box truck when available.

Unloading Your Kiln

Once your kiln arrives, the customer is responsible for moving the kiln from the delivery point to its final location unless a separate moving or installation service has been arranged.

Hire a Local Moving or Package-Handling Service

Many customers choose to hire a local moving or package-handling service experienced with heavy equipment. These teams can help off-load the crate and move the kiln into your workspace for an additional fee.

This option is especially helpful for larger kilns, tight spaces, or customers who do not have the proper unloading equipment available.

Unload the Kiln Yourself

If you prefer to handle unloading yourself, make sure you have the proper equipment and enough help available. Depending on the kiln size and weight, this may require a pallet jack, dolly, forklift, loading dock, or similar equipment.

Planning ahead before delivery helps make the unloading process safer and smoother.

Inspecting Your Shipment

All Paragon shipments are FOB origin, meaning ownership transfers when the kiln leaves Paragon’s facility. Inspection upon delivery is essential.

Please inspect your shipment carefully before signing for delivery.

If There Is Minor Visible Damage

  • Note the damage on the delivery paperwork before signing.
  • Take clear photos of the packaging and any visible damage.
  • Accept the shipment if the damage appears minor.
  • Inspect the kiln immediately after unpacking.
  • Contact Peach State Pottery as soon as possible.

If There Is Severe Visible Damage

  • Refuse the shipment if the damage appears severe.
  • Take detailed photos before refusal.
  • Contact Peach State Pottery right away.

If You Discover Concealed Damage

Concealed damage is damage discovered after the kiln has been unpacked.

  • Notify the carrier and Peach State Pottery as soon as possible.
  • Keep all packaging materials.
  • Take detailed photos and/or video.
  • Report the issue within 5 days of delivery.

Photo & Video Documentation

Before opening the crate or box, take clear photos or video of the packaging from all sides.

Continue documenting as you unpack, especially if you notice broken crate boards, crushed packaging, holes in the box, visible impact marks, or any visible damage to the kiln or accessories.

This documentation is essential to help support a freight claim if damage is discovered.

If a claim is needed, documentation may include the carrier’s claim form, bill of lading, Paragon invoice, freight bill, inspection report, photos, videos, and repair estimate.

Returns & Exchanges

Paragon kilns are specialty products, and many models may be made to order, custom, or freight-shipped. Please review the return policy carefully before purchasing.

Return Eligibility

  • The return or replacement request must be initiated within 30 days of the delivery date.
  • The kiln must be unused.
  • The kiln must be in original condition.
  • The kiln must be returned in its original packaging.
  • A Return Merchandise Authorization, or RMA, must be approved before the kiln is shipped back.

Please do not ship any kiln back without first receiving return authorization.

Original shipping costs are not credited or refunded. Return shipping is the customer’s responsibility unless otherwise stated under an approved warranty claim.

  6. If approved, your refund or credit will be processed.

Refund approval depends on the kiln arriving unused, in original condition, and properly packaged.

Custom & Special-Order Products

Custom or special-order Paragon kilns are not eligible for return unless covered by an approved warranty claim.

Refunds

Once your return is received and inspected, you will be notified whether your refund has been approved or rejected.

If approved, the refund will be issued back to the original payment method. Please allow time for your bank or credit card company to process the refund after it has been issued.

Late or Missing Refunds

If your refund has been approved but has not appeared yet, please check your bank or credit card statement, contact your card issuer or bank, and then contact Peach State Pottery if you still need help.

Sale, Promotional, and Scratch & Dent Items

Only regular-priced items may be eligible for refund.

Sale items, promotional products, and Scratch & Dent products are not refundable.

What the Warranty Covers

During the applicable warranty period, Paragon Industries, L.P. will repair or replace parts that become defective under normal and proper use, provided the kiln has not been subjected to misuse, improper installation, freight damage, modification, or any of the exclusions listed in this policy.

At Paragon’s discretion, warranty service may be handled in one of the following ways:

  • Paragon may furnish and install replacement parts at the factory, with transportation costs to and from the factory paid by the owner.
  • Paragon may request that defective parts be returned to the factory for examination.
  • After factory review, Paragon may provide replacement parts with installation instructions, shipped postpaid to the owner.

The warranty on repaired or replaced parts is limited to the remaining, unexpired portion of the original warranty period.

Warranty Exclusions

The Paragon warranty does not cover damage or issues caused by:

  • Overfiring, including firing beyond the melting temperature of the material being fired, regardless of the cause.
  • Damage to ware, tools, kiln furniture, or anything inside the kiln caused by overfiring.
  • Allowing the kiln to exceed the maximum temperature shown on the kiln’s nameplate.

Modifications & Unauthorized Changes

The warranty may be voided if the kiln is altered, modified, tampered with, or adversely affected by attaching any feature, device, or accessory without express written permission from Paragon Industries, L.P.

Freight Damage Is Not Warranty Damage

Damage caused during shipping or freight delivery is not treated as a warranty defect. Freight damage must be documented at delivery and handled through the freight claim process.

Please inspect your shipment carefully before signing for delivery, take photos or video before unpacking, and report visible or concealed damage as quickly as possible.
