Does a colored pencil contain lead?
It is a common misconception that pencils contain the element lead, probably brought about by the middle part of a pencil being called lead. In fact no pencils contain lead instead using carbon based materials (or in the case of coloured pencils, a type of coloured clay). Coloured pencils have been around since the 1920s. They were originally created from colours and pigments suspended in a waxy base with natural binding agents and often fillers. Lead was not an ingredient in coloured pencils at that time. As the industry has advanced, manufacturers have become more aware of ingredients that can be harmful to people and have reduced the use of toxins in their products. Therefore it is even less likely for there to be lead in modern coloured pencils.
How long to leave putty to dry before painting?
Putty should not be allowed to dry completely. If it does, then it will become brittle and may shrink and crack. The main purpose of putty is to form a seal between the glass and the wooden window frame. The putty should be painted to seal in the linseed oil which keeps it pliable. A film of hard putty on the surface forms after 2 to 3 weeks (weather dependent) and then the painting should be carried out to stop any further drying of the putty.
