This was a wonderful tour. You can see all the stages in the production process and even get to try throwing a pot yourself. Now that was fun!
Everyone at the factory was friendly and welcoming, and Martina, the guide, went above and beyond the call of duty. She not only took me on a wonderful tour but picked me up at the train station and gave a (delicious!) local recommendation for lunch afterwards.
I cannot possibly recommend this tour more, especially for solo travellers. So many experiences turn out to be "minimum 2 participants" or prohibitively expensive. This was fun, interesting and a morning well-spent. One other point is that it's a simple, short, cheap and comfortable train ride from Bratislava.
