Would Olivine If Added To A Glaze Produce Green Flakes?

Recommended Posts

I have a good supply of olivine, a magnesium iron silicate also known as paridot. The Insight database calls it a refractory that melts around 2800F. Would olivine dust of about 40 mesh when added to a glaze result in green flecks?

 

Does anyone have any experiance with it? If not, I will post my test tile results.

I'm of the try it school also.

 

However even if the melting point of the PURE material is 2800 F....... remember that yopu will be suspending the mateial in a liquid solution of other oxides that can have a fluxing interaction at the edges of the particles.  All bets are off.

 

best,

Thanks Marcia and John. I have not found a single article or mention of using this stuff in glazes. There were articles about its use in foundry sands and that is about it. This time I might not be reinventing the wheel. On the other hand, there may be a good reason why it's not mentioned. We will see.
