Nuanchu 12 Inch Tempered Frosted Glass Paint Muller Slab Mineral Pigment Grinding Plate for DIY Oil Painting Watercolor Oil Acrylic Painting

II love this item. It's well made and sturdy. It has a smooth side and a very slightly rough side. The 12" x 12" is a perfect size.The only reason I gave this one star is because it had chip on one corner, with a jagged edge.Edit: I was able to return the damaged item, and received a replacement.

this is the second plate i’ve owned and i prefer this one. the first one i got off etsy and it’s fine, but kind of small and only part of it is frosted. i like that this is thicker and solid, i don’t feel like i’m going to break it. a good price for a beginner

Would not recommend. This plate shattered into numerous jagged pieces the second time I used it for grinding pigment. It was used properly, stored carefully, and handled gently, yet is just exploded into shards while I was mulling. The pieces were irregularly sized and conchoidally fractured, leading me to believe this item was not tempered properly and the overall quality was low.
