Step 6: Cure
Note: This phase is essential to obtain a strong, good quality container. Do not take any short cuts!
If the container is allowed to dry out, even once, during the next 10 days, the container will be weak.
Cover the empty container with wet sacks.
Wet the sacks 3 times per day and continue doing this for 7 days (1 week).
On the 7th day of curing, fill the container 1/4 full with water and recover the container with wet sacks.
On the 8th day, fill the container 1/2 full with water and recover the container with wet sacks.
On the 9th day, fill the container 3/4 full with water and recover the container with wet sacks.
On the 10th day, fill the container completely with water and recover the container with wet sacks. Leave for 5 days.
On the 14th day, empty the container and wash it out with clean water.
After the final washing the container is now ready for use.
With care you can transport the newly made container over many kilometres without fear of breaking it, provided you are careful.
