Pink Bodystain As Glazestain Problems

[marlies lies]

Hi,

I have been advised that a bodystain is no different as a glazestain and a bodystain can be used as a glazestain and vice versa.

I have fired a batch of testtiles with a pink Al-Mn bodystain mixed with 3 tipes of baseglazes I usually use for stains, and the result has been disappointing, with almost no coloration, and not a good melt.

I have been trying to find out what went wrong, and found on digital fire a sentence that sais that bodystains normally do not melt appropriately when used as glazestains.

I have also found in Matthes that if you use a Al-Mn pink stain you have to use a High viscosity glaze with a lot of Al2O3 and little ZnO and or B2O3.

One of the glazes has ZnO so that is logical.

The other glazes have no ZnO and B2O3 of highest 0.33, lowest 0.20.

 

What do you think went wrong?

 

Is there anybody who has experience in using bodystains as glazestains?

If you are using Mason stains I highly recommend you call them to ask for guidance. Their tech department is VERY helpful. I have always been surprised at how nice they are to small quantity users.

Pink stains are notoriously touchy. They are very dependent on the composition of the base glaze in order to achieve their best color. As Chris said, call the manufacturer and get their recommendations on how best to use those stains.

thanks! I wrote them a email, since I live in the netherlands and your day is my night ;-) Now waiting for their answer.

If I get it I will post it here, there are probably more people who love pink :-)
