The Hartley & Noble Premium No-Warp Guarantee
Available on eligible Premium Throwing Batts and Tile Batt Systems bought directly from Hartley & Noble.
Intro section
At Hartley & Noble, we design and make pottery equipment to help make potters’ lives easier.
One of the frustrations potters often face is batts that warp, twist, bow or move during use. Our premium batt products are made from materials and manufacturing methods chosen for stability, strength and reliability in real pottery use.
That is why eligible Premium Throwing Batts and Premium Tile Batt Systems bought directly from Hartley & Noble are covered by our No-Warp Guarantee.
What the guarantee covers
Our No-Warp Guarantee covers eligible premium batt products that develop measurable warping, twisting or bowing of more than 3 mm during normal pottery use.
A product may be considered warped if it no longer sits flat and stable on a suitable flat surface and the raised area measures more than 3 mm without pressure being applied.
The guarantee applies to the affected component only. For example, if one batt, insert or tile has developed a qualifying warp, we will assess and replace that specific component where the claim is approved.
Eligible products
The No-Warp Guarantee applies only to selected premium products bought directly from Hartley & Noble.
This includes:
- Premium Throwing Batts
- Premium Tile Batt Systems
- Premium batt system components listed as eligible on the product page
The guarantee does not apply to Economy products unless clearly stated on the product page.
Suggested website wording:
Look for the No-Warp Guarantee badge on eligible product pages.
That keeps it flexible. You can add the full product list later without rewriting the policy.
Direct purchase only
The No-Warp Guarantee is an exclusive benefit for customers who buy directly from Hartley & Noble.
When you buy direct, we can verify your order, support you personally, and assess any claim with you properly.
Products bought through retailers, stockists or third-party sellers should be handled through the returns and aftercare process of the business they were purchased from.
This does not mean we do not support our stockists. It simply means the Hartley & Noble No-Warp Guarantee is an additional direct-purchase benefit available only on orders placed directly with us.
What is not covered
The No-Warp Guarantee does not cover:
- Economy products
- Products not listed as eligible
- Products bought through retailers, stockists or third-party sellers
- Accidental damage
- Dropping the product
- Cracks, chips or broken edges caused by impact
- Damage caused by incorrect storage
- Products left soaking in water
- Products stored wet for prolonged periods
- Exposure to excessive heat, direct sunlight, damp or extreme conditions
- Products that have been modified, drilled, sanded, cut, sealed or altered
- Normal clay staining, surface marks or cosmetic wear
- Movement caused by dried clay, debris, an uneven wheel head, incorrect fitting or an unsuitable surface
- General wear and tear from normal use
Important wording for your over-the-wheel issue:
If an Over the Wheel Batt System is dropped and the edge cracks, chips or breaks, this is treated as accidental damage and is not covered by the No-Warp Guarantee.
That needs to be explicit because you already know this failure mode exists.
How claims are assessed
All claims are assessed through a live video call.
We do this because photographs often do not show the issue clearly enough. A live call allows us to guide you through the check, view the product properly, and confirm whether the issue meets the No-Warp Guarantee criteria.
During the call, we will ask you to place the product on a suitable flat surface and measure any raised area using a ruler or measuring tool.
If the product is confirmed as having a qualifying warp of more than 3 mm, we will replace the affected component.
What happens if the claim is approved
If your claim is approved, Hartley & Noble will replace the affected component.
The guarantee does not automatically entitle the customer to a full replacement system unless the main system component itself is confirmed to have a qualifying warp.
Replacement decisions are made by Hartley & Noble after completing the live video assessment.
Statutory rights note
Add this at the bottom:
This guarantee is offered in addition to your statutory rights and does not affect your legal rights as a consumer.
Keep that line in. It is important.

How to Make a No-Warp Guarantee Claim
Step 1: Check your product is eligible
Before starting a claim, please check that:
- You bought the product directly from Hartley & Noble
- You have your order number or proof of purchase
- The product is an eligible Premium Throwing Batt or Premium Tile Batt System
- The issue is warping, twisting or bowing — not accidental damage, cracking, impact damage or general wear
The No-Warp Guarantee only applies where the product has developed a measurable warp of more than 3 mm during normal pottery use.
Step 2: Contact us
Contact Hartley & Noble with:
- Your name
- Your order number
- The product name
- A short description of the issue
- When you first noticed the problem
Once we have checked the order and product eligibility, we will arrange a live video call to assess the product with you.
Step 3: Prepare for the video call
For the video call, you will need:
- The affected product or component
- A ruler or measuring tape
- A suitable flat surface
- A phone, tablet or laptop with camera
- Good lighting
- Enough space to place the product flat
- Ideally, a tripod, phone stand or someone available to hold the camera
The camera needs to show both the product and the measuring point clearly.
This is important: if we cannot see the product and measurement clearly during the call, we may not be able to approve the claim.
Step 4: Use a suitable flat surface
Please use a solid, rigid, visibly flat surface such as:
- A granite worktop
- A stone countertop
- A glass table
- A flat kitchen worktop
- Another hard, level surface
Avoid soft, flexible or uneven surfaces such as:
- Carpet
- Fabric-covered tables
- Plastic garden tables
- Uneven wooden benches
- Pottery wheels with clay residue
- Any surface that visibly rocks or bends
If the surface does not appear suitable during the call, we may ask you to repeat the check on a different surface.
Step 5: Complete the Live Flatness Check
During the video call, we will guide you through the check.
You will be asked to:
- Clean and dry the product.
- Place it on the flat surface.
- Leave it resting naturally without pressing it down.
- Show whether any part lifts from the surface.
- Measure the highest lifted point with a ruler.
- Show the product from the side and from above.
- Confirm whether the product has been dropped, soaked, stored wet, modified or exposed to unusual conditions.
A claim may be approved if the product shows a measurable warp, twist or bow of more than 3 mm and the issue is not caused by accidental damage, misuse, incorrect storage or unsuitable use.
Step 6: Claim decision
After the video assessment, we will confirm whether the claim is approved.
If approved, we will replace the affected component.
If the issue is not covered, we will explain why. For example, the product may show signs of accidental damage, impact damage, cracking from being dropped, incorrect storage, modification, or movement caused by an unsuitable testing surface.
