Painters Tip

Information about White

I like to use all of the below whites but I use Permalba White instead of zinc white alone. Permalba is a combination of whites. It is very creamy. I use it a lot in the winter.

Titanium White - titanium dioxide (oxide)Reflects 97.5% of all available light. Most opaque white, perfect choice for direct painting but difficult for color mixing because it takes so much color to tint Titanium. Titanium is completely inert, does not change by aging or normal chemical action, but it does require more oil to grind than other whites and can show some yellowing because of the darkening of linseed oil when it dries. It does not dry very quickly and is more Zinc white in this respect. Titanium White does not dry as hard as Zinc white eventually will, and consequently will make a more flexible film.

Flake White - basic carbonate of lead Flake white has a heavy pigment requiring very little oil, and combines in time with oil to make a very flexible film. It is regarded as the most reliable white on which to build a painting. It can be applied more heavily than other whites with less danger of cracking than other whites. Flake white dries well and is a "warm" white. Note: Being composed of lead, Flake white is poisonous it absorbed into the body, but this does not happen by external contact.

Zinc White - zinc oxide The most popular and transparent of the whites, it is also slow drying. It is a "bluish" (cold) white color, not nearly as strong and opaque as Titanium White and therefore can be very easily controlled. Zinc is recommended for scumbling and alla prima painting. Impressionists who painted directly liked Zinc White for its transparency and slow dry time. But Zinc's slow drying time and brittleness does not make it a good choice for general painting.
