The use of titan and rutile

Recommended Posts

Generally, Titatium Dioxide would be used as an opacifier, but doesn't work as well as Tin or Zircon-based opacifiers. Rutile is typically used as a colorant, for buttery yellow colors in oxidation, and sometimes grey in reduction. The greatest benefit of both is that they tend to grow crystals in glazes, which is a good way to create matteness, or just add interest to an otherwise boring glaze.

Thank for replying. How about the amount for both in glaze mixture? Because when I used rutile 15%, the glazed became pinhole and little bit harsh. Was it rutile effect? :rolleyes:

Rutile glazes in reduction fire (thats my area of experience) can be problematic with pin holing

I have used a rutile base glaze for many decades by the ton and have seen my share of pinholes-Firing schedules-reduction amounts-glazing procedure-dusty dirty bisque ware can all be factors .

I like tin and zircon to opacify over Titanium Dioxide as noted above
