Recently, we’ve had several customers ask what material the the Wonder Junior Hand Mill stone heads are made of. Hopefully this article will shed some light on it.
The stones are made of Naxos-basalt. What is this, you may ask? Basalt is a type of volcanic rock, this specific variety from the Mediterranean island of Naxos. It is a very durable rock commonly used in a variety of mills as well as for whetstones (stones for sharpening knives). Naxos is one of the many islands that make up the Cyclades in the Aegean Sea (off the coast of Greece). The region is one of the few places in the world where you can still acquire natural white basalt stones and marble.
The stones for the Wonder Junior are then made from granules of basalt combined with a magnesite cement. The cement has a similar hardness to the basalt.
Using the stones as opposed to metal does improve the grind as the stones will stay sharper and are able to provide a finer grind. For the Wonder Junior, this means approximately 20% finer flour than when using the steel heads which come with it.
We’re curious, though, to hear what our customers and others have to say about the stones. Have you used them, and what do you think?
