On The Subject Of Low Fire (Cone 04) Glazes, Is It Possible To Make A Floating Blue In This Firing Range? The Only Ones I Have Seen Have Been Cone 5-


Recommended Posts

given the lack of response to this querry I am assuming that no one has a recipe for an 04 floating blue or rutile blue glaze.  Is there some reason that would make this type of glaze difficult to make? I guess I will try out the experimenting thing again..after all it worked out pretty good with the Gerstley Borate substitution..lol

Hi, floating blue is a rather special glaze... many factors going on at once... still, many cool floating-like effects can be achieved at lowfire.

Digitalfire has an article on variagated glazes you might enjoy reading.

 

At low fire temperatures layering seems to be the key... extending the firing/cooling time can help.

 

A high boron glaze (using for example frits 3124,3134, 3195, gillespie borate, etc...) with titanium dioxide (around 5%) or rutile is a good starting point. A wash, well more like a glaze saturated with rutile/TiO2, applied thinly over other glazes can also do the trick. Applying over dark opaque glazes/slips can help. Bone ash is another interesting material.

 

Adding small to tiny amounts of iron, copper, chromium, manganese, burnt umber can help you get a toned down blue or to get different colors.

 

Stains are also worth a try...

 

 

Chappelle's book has leaded glaze recipes that when layered create a variagated effect. I stay away from lead, but some people are ok with using it...

 

I don't know if zinc oxide has the same effect at cone 04-03, because I haven't tried it...

 

Also, please keep in mind that not every nice looking glaze is foodsafe.
