Big fan and user of all the guests materials, thankyou for the interviews, but one word of caution on using zinc in linseed oil. In the best oil painting art practice, zinc is no longer used. It causes embrittlement of the paint film and has become the bane of the art conservators world. The best oil paint manufacturers and practitioners no longer use it, although there is some research that suggests that 3% or less can be acceptable. Sadly, lead still makes for the most durable white oil paint.
