 | The parts don't fit together as perfectly as the pictures in the guide would have you believe: it's still a masonry project, with parts whose dimensions aren't always perfect. We had quite a few gaps between some of the voussoirs, but don't worry if this happens to you - they'll be filled later with refractory mortar. |

 |  |
 | We used small wooden wedges, which can be pressed in to adjust the overall structure (see photo in step 5). |
 | You can also use the sheets of paper used to wrap certain parts on the pallet. |
 | We did as they said... |
 | Be careful, with this water/mortar ratio, you'll end up with a very liquid paste. If you have a big day, you run the risk of getting everything through. To avoid this, we put pieces of cardboard, wedged with pieces of wood, inside the oven, against the days in question. |
 |  |
 | The hearth must be sheltered from the elements, but air must be allowed to circulate for better drying. The hearth is finished. Next: dressing the hearth. Previous step: The foundations. |
