What kind of tools did they use for building, daily work and brick materials?
The missions had most of the same tools that you would have found in any civilized country in late 18th century. They brought tools with them and early in the history of each mission high priority was given to creating workshops (carpentry shops, a blacksmith shop etc.).
The initial buildings were made of wood and local materials. Ultimately they built buildings of adobe brick, using the local soil and hay.
