What is it made I'm not sure, but it seems to have a slightly softer plastic mixture, a very slightly rubbery plastic.
However, the mortar tub had a strong odor so bad that I could not imagine for the life of that which can be healthy, especially because I also want to eat the horseradish :) My husband told me to the tub just outside in winter leave, leave full snow and eventually the smell would be gone.
What can I say, I had the pan stand throughout the winter outside, she left full of snow. When I brought them into the house, I have washed with detergent and Antikalkspray and the green side of the sponge thoroughly, scrubbed, rinsed ... The smell is still there, even though it is now for some time in the heated living room. Whatever you try, the strictly chemical smell will not go away. He's just not as strong, you can smell it only if you can smell it, and no longer in two meters as previously. But it's also no bath for food or garden, but for mortar. And for that, that's probably as fine.
Since I currently to lift a mortar, I use it now for the storage of wood for the fireplace. But it is also ideally suited as quite stable!
The only drawback, what else you could find fault:
The pan has not kept the same shape and dimensions as on the product picture here, but it is slightly lower and more elongated.
So, for the horseradish I look now on to a suitable vessel to large. I was thinking that it would be what with the cheap mortar tub, but I must now probably still pick from the garden needs a more expensive option. Keep for mortar probable and firewood suitable (but of course not put beside the fireplace, which indeed is probably clear in plastics :)
