Hey, oven lovers! This is a tiny little post to show you that the clay:sand mixture we use to build these super ovens can be recycled (or rejuvenated).
As you will see, if you read my previous post, I had to do some pretty major repairs to my oven recently. Anyone who has gone to the effort of building one of these ovens will tell you that the most tedious part of the whole process is puddling the clay:sand mixture. It is hard work and very boring so, while you are going to the bother of doing it, I recommend mixing a little more than you need and storing the extra in plastic sacks. You will use it for filling cracks and maybe, one day, to undertake more major repair work. You might also need to partially, or even wholly, remove one of the dry layers, particularly if you abuse your oven as much as I have mine. Well don’t throw that dry stuff away, and if your bagged material is dry, make sure you keep that too.
All you need to do is add some water to it, leave it for a while and, hey presto, it’s as good as new. Sweet!!
