What your looking for can be found if you search using the term “Specular” which means in this case, Mirror finish. I purchased one of these a couple of months ago. It produces a glass-like texture. However, you will not want to use any adhesive on it so it is solely useful for PLA. I tried both PETG and PC and both left indelible marks on the plate.
I also have a smooth Engineering and I temp plate and they simply don’t produce such a glass like finish even though it is my favorite plate. Although I will say these two smooth surfaces from my Bambu plate are perfect when creating flat smooth surfaces that one may want to later glue. Texture interferes with that process.
