Zircon Flour


Recommended Posts

My use of milled Zircon shows me its an extremely tough and high melt material-I use it in kiln coating with colloidal silica.

Hemer koalin flashes well if that helps.

I would be interested in any Zircon that would melt and flash?

Wow the melt point for Zircan flour is 2200-C so its going to still be there.

My zircon is from Laguna and its milled to 300 mesh if I recall.

I can look in my laguna book in am  on this stuff as I left studion after a 12 hour glaze and load day and Im staying out till I turn kilns on in am.

I am wooped.

 

Let us know how this turns out when you try it.

Is Zircon usually sold as Zirconium Silicate or is that a different beast.

I have a bucket of Zircon, like very fine sand, it used to be mined from a beach close by, along with ruitile and ilmenite. When you leave those beaches your feet are black from the rutile and ilmenite deposits.

My update laguna book (4/11)

says Zircon,G milled ZrSiO4

an opacifier which controls texture and craze resistance in glazes.

I use it as I said as a kiln coating.

 

looks like zircopax plus is the same chemical-ZrSiO4 and the book says it replaced Ultrox and regular Zircopax and superpax which are no longer avaliable it says
