What is the difference between Ferro 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….Fixing a glaze mistakenly made using frit 3134 instead of 3124.

What is Frit 3124?

Frit 3124 is a leadless high calcium borosilicate frit common to low fire glazes. This frit has a chemistry similar to an alumina addition to Frit 3134.

What is Ferro frit?

Ferro Frit 3134 is considered a ‘Boron’ frit. It is a general-purpose flux for partially fritted glazes. Fusion Temp: 1450 F. Flow Temp: 1600… Frits are combined raw materials that are mixed, fired, melted, crushed and ground into a powder.

What is borax frit?

A frit is a type of ceramic glass. Borax Frits Borax frits are often used in the production of earthenware glazes when a lead free glaze is required. Slight milkiness, especially at lower temperatures, may be evident over red clays, and the colour response with oxides, etc. is not usually so vivid as with lead frits.

What is frit used for?

Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides.

What does Gerstley borate do in a glaze?

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.

What does Zircopax do in a glaze?

Zircopax affects glaze melt viscosity, surface smoothness, thermal expansion and color development and can be implicated in a range of glazes faults associated with these.

Is frit a flux?

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.

Is borax the same as borax frit?

Although the boron in the frits is no longer in the form of borax, it is common to use the term “Borax Frit” in recognition of the source of the borate. Borax is widely used as a flux and glass former at almost all temperature ranges, but especially with earthenware.

What is 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 a frit pattern?

Silk-screened ceramic frit patterns on glass can reduce bird collisions with windows as they are always visible, even with strong reflections. The Bird Safe Frit Pattern includes options with white ceramic dots covering 20 percent of the glass or 1/8” lines on the outermost (1st) surface of the glass.

Is Gerstley borate toxic?

Gerstley Borate has a relatively low acute toxicity. Small amounts (e.g. a teaspoonful) swallowed accidentally are not likely to cause effects; swallowing amounts larger than that may cause gastrointestinal symp- toms.

What’s the difference between frit 3124 and frit 3195?

These contain boron (B 2 O 3 ), it is magic, a low expansion super-melter. Frit 3124 (glossy) and 3195 (silky matte) are balanced- chemistry bases (just add 10-15% kaolin for a cone 04 glaze, or more silica+kaolin to go higher). Consider Frit 3110 a man-made low-Al 2 O 3 super feldspar. Its high-sodium makes it high thermal expansion.

What’s the difference between Ferro 3124 and Ferro 3134?

These two frits have one difference in the chemistry: Al2O3. These two boron frits (Ferro 3124 left, 3134 right) have almost the same chemistry. But there is one difference: The one on the right has no Al 2 O 3, the one on the left has 10%.

What kind of glaze is frit 3124 for?

Like Frit 3124, this can be a complete cone 06-02 leadless glaze with the addition of a little kaolin to suspend. Adding more kaolin and silica will produce glazes suitable for higher temperatures. Substitute in some Frit 3110 if glazes shiver or 3249 if they craze.

Which is better Ferro frit 3124 or fusion F-75?

Frit 3124 has five times the amount of Al 2 O 3 (the second most important oxide in glazes) and half the amount of boron (the main melter). The glaze chemistry approach is much better, and easier than you think. To be able to do it you need two other Ferro frits, 3110 (or Fusion F-75) and 3195 (Fusion F-2).
