MDF Material Soak Test ResultsBefore we developed our range of pottery batts, we carried out soak tests on a range of wooden fibreboard materials. Our research identified that potters were sick of cheap batts that splintered and warped. So we wanted to find a better alternative.
We submerged various materials in water for 48 hours. We wanted to observe how much they would swell and warp when they get wet. The results speak for themselves.
This helped us choose the range of MDF that we make our products from. As you can see from our video, traditional marine ply soaked up water and there is a visible wobble. Our Premium MDF performed incredibly well; with only 1% swelling and NO WARPING 🙌 Economy MDF did absorb water, and showed minor signs of warping.
We decided to make ALL of our Tile Batt Systems from Premium MDF. Even when we cut the tile hole out of the centre, the batt structure remains strong and resilient so that this product will last for years.
We make our standard Throwing Batts from either Economy, or Premium MDF. This ensures that potters have a choice to buy a product that fits within their budget and is fit for purpose. If choosing economy we recommend that you go for a stronger 9, or 12mm thickness.
We do not use marine ply or cheap bendy wood... ever!
