Frit makers in Morbi and elsewhere in Gujarat mainly make frits for the tile industry: transparent, opaque, matt and engobe frits, in grades for different firing temperatures. Some also make frits for sanitaryware glazes and for enamel on steel.
The tile cluster is the reason. Hundreds of plants nearby need glaze every day, and frit makers grew up to supply them. If you are new to the material, start with what ceramic frit is and who buys it.
The main families
Makers name their grades differently, but supplier listings from Gujarat show the same broad families again and again.
- Transparent frits give a clear, glossy glass layer that lets the printed design or body colour show through.
- Opaque frits, often opacified with zirconium silicate, give a white covering layer that hides the body colour.
- Matt and satin frits give a low-gloss surface; makers also list crystal matt and matt transparent grades.
- Engobe frits go into the layer between body and glaze, which hides the body and helps the glaze fit.
- Titanium opaque frits are mainly used for enamel on steel and some special glazes.
Grades by firing and product
Within each family, makers offer grades for different firing conditions. A frit for porcelain floor tiles must melt properly at a higher temperature than a frit for a wall tile fired at a lower temperature.
Single-fired tiles, where body and glaze are fired once in a fast kiln, need a frit that releases gas and smooths out in a short cycle. Double-fired wall tiles allow a different glaze recipe. Sanitaryware glazes are fired in a longer cycle and have their own needs.
So a frit name alone tells you little. Ask the maker which product, firing temperature and cycle a grade was designed for, and ask for its technical data sheet.
Granules and special effects
Some makers also sell frit in coarser granules, often called grits or dry glazes. These are spread or fixed on a tile surface to give texture, sparkle or a raised effect. They are common on decorative wall tiles and some structured floor tiles.
Lead-free frits are the norm for tile and sanitaryware work. If your customer needs proof, ask for a chemical analysis that reports lead and cadmium, not just a statement.
Choosing a grade
- Tell the maker the product, the body type, the kiln type and the firing temperature and cycle.
- Ask for the data sheet: chemical analysis, thermal expansion, softening and melting behaviour.
- Trial a sample in your own glaze and kiln before any order; see what tests apply to frits and glazes.
- Check that the maker melts its own frit. Some sellers only repack frit bought from a furnace operator.
- Ask how the maker keeps grades consistent from batch to batch, and what tolerance it holds on expansion.
