What can I use instead of Ferro frit 3134?
Frit 3134 is low-alumina/high-boron, 3124 is medium-alumina/low-boron and 3195 is medium-alumina/high-boron. Boron is the melter. Alumina thickens the melt and hardens the glass. Just from this it appears that Frit 3195 is a better starting point for calculations to replace frit 3134.
What is the difference between frit 3124 and 3134?
Fortunately, these frits are similar. Except for one thing: Frit 3134 has almost no Al2O3 (3124 has lots) and significantly less SiO2. That is a game changer, making it melt dramatically more and lower. Not surprisingly then, her glaze melted way too much, running off the ware.
Is Frit 3134 a flux?
-It has high boron. That gives it a lot of bang-for-buck as a flux, especially in middle temperature. -It has a very high CaO content. That makes it useful for developing chrome-tin pinks and maroons.
What is a frit in pottery?
A frit is a type of ceramic glass. It is a combination of materials that, when melted together, are rendered insoluble and resistant to acid attack. They are, therefore, a means of introducing certain materials into a glaze which would otherwise be toxic.
What is a substitute for Gerstley borate?
IMCO Borate is a blended product that is a direct substitute for Gerstley Borate. They say it “has the same physical properties as Gerstley Borate. It mixes with water to form a creamy slurry that gels and keeps the glaze from settling.
What is a ferro frit?
Frits are glaze materials which have been melted, cooled, and ground into a powder which is then added to a glaze formula for the purpose of rendering insoluble any soluble materials. The use of frits also allows for the incorporation of certain raw materials in the creation of glazes.
What is Gerstley borate?
Gerstley Borate is a sodium-calcium-borate compound used in ceramics as a low and mid-range temperature flux. It is essentially a source of boron in glazes, and acts as a melting agent. It also can act somewhat as an opacifier and prevent crazing.
Is dolomite a flux?
Calcium carbonate and dolomite are refractory when used pure However, put either of these in a mix with other ceramic minerals and they interact strongly to become fluxes.
What is a high alkaline frit?
A highly alkaline frit used as a basis for raku glazes. Produces intense alkaline colours when used with oxides which have a crazed appearance.
What is frit made out of?
A frit is a combination of a flux or several fluxes (lead, borax, boric acid, potassium carbonate) that is combined with other in- soluble materials (quartz, feldspar, lime etc.), melted in a kiln to form an insoluble glass, and ground to be used as the base for making glazes.
What is frit powder?
USING NORTHSTAR™ GLASS FRITS AND POWDERS. The term “frit” refers to granular crushed glass. Soft glass frits have been available to glass artists for a long time in many colors and several different mesh sizes.
Is Gerstley Borate a frit?
The Gerstley Borate is a natural source of boron (with issues frits do not have).
