Rublev Colours Pigment Lead-Tin Yellow Light (Type I) - 50 g

There are, in fact, two types of lead-tin yellow, designated as types I and II. Type I is lead-tin oxide and is most frequently found on old paintings. Type II is a second variety of lead-tin oxide that may contain free tin oxide and additional silicon. Possibly both types were used as opacifiers in ancient glasses. Lead-tin yellow (type I) is prepared by heating in a crucible a mixture of lead dioxide and tin dioxide to a temperature of about 800° C. Warmer hues of yellow appear at lower temperatures and at about 700–800° C, the more lemon-colored hues develop.

Lead-tin yellow contains lead and is poisonous. Utmost care should be used in handling the dry powder pigment to avoid inhaling the dust.

WARNING: Exercise care when using dry pigments. Do not eat, drink or smoke. Avoid breathing dust. Use a NIOSH-certified dust respirator. Wash hands immediately after use. If the creation of dust is likely, wear protective clothing.
