Baking boards of bakers are tamei. [But those] of householders are tahor. If he painted them with red paint or painted them with saffron [dye], they are tamei. [Regarding] a baker’s shelf that was fixed onto a wall, R’ Eliezer rules it tahor, but the Sages rule it tamei. A utility plate of bakers is tamei, but [the plate] of householders is tahor. If one made a rim on its four sides, it is tamei. If it [subsequently] becomes broken open on one side, it is tahor. R’ Shimon says: If one prepared it so that he may slice [dough] upon it, it is tamei. Similarly, the rolling pin is tamei.
