STUPIUM. “Long-term contact with lead(II,IV) oxide may lead to accumulation of lead compounds in organisms, with development of symptoms of acute lead poisoning. Chronic poisoning displays as agitation, irritability, vision disorders, hypertension, and a grayish facial hue.” (Red lead pigment). https://en.m.wikipedia.org/wiki/Lead(II,IV)_oxide View in LinkedIn

VERY TOXIC PAINT. “When inhaled, lead(II,IV) oxide irritates lungs. In case of high dose, the victim experiences a metallic taste, chest pain, and abdominal pain. When ingested, it is dissolved in the gastric acid and absorbed, leading to lead poisoning. High concentrations can be absorbed through skin as well, and it is important to follow safety precautions when working with lead-based paint.” Red lead pigment should have been called stupidum in Latin not stupium for rinse. https://en.m.wikipedia.org/wiki/Lead(II,IV)_oxide View in LinkedIn

MINIUM. “Lead(II,IV) oxide, also called red lead or minium, is the inorganic compound with the formula Pb3O4. A bright red or orange solid, it is used as pigment, in the manufacture of batteries, and rustproof primer paints. It is an example of a mixed valence compound, being composed of both Pb(II) and Pb(IV) in the ratio of two to one.” https://lnkd.in/d9WpCnR View in LinkedIn

GLUE FOR BINDING GOLD TO BOOKS. “Take the bladder of a fish, known as the sturgeon, wash it three times in lukewarm water, cut it up into pieces and, putting it in a very small pot with water, allow it to soften overnight. In the morning...test the glue.” https://lnkd.in/d7yzXt5 View in LinkedIn

GRINDING COLORS INTO SAP GREEN. “Take the gum which oozes from the cherry or plumb tree, cut it up very small, and place it in an earthenware pot. Pour in plenty of water, and place it in the sun, or in the winter over a fire until the gum melts. Then strain it through a cloth and, with this (drying) medium, grind the colours.” https://lnkd.in/d7yzXt5 View in LinkedIn

PARAMETERS CONSIDERED. “Here we analyze the physical properties of proposed anisotropic star models. We examine the viability of metric potentials and investigate the effective energy density, effective radial and transverse pressure components, anisotropic parameter, mass-radius relation, energy conditions and stability for different values of the coupling parameter.” https://www.sciencedirect.com/science/article/pii/S0577907319309773 View in LinkedIn

TINFOIL PREPARATION. “Beat pure tin very thin...rub it with cloth and charcoal...and a boar’s tooth until it shines. Get some switches of green wood, which you cut in April, split them down the middle and dry them over smoke. Then remove the outer bark and scrape the inside, which is yellow, into a clean pan adding a fifth part saffron. Over this pour plenty of old wine or beer, and when it has stood overnight, heat it in the morning over a fire until it is lukewarm...” (etc). https://lnkd.in/d7yzXt5 View in LinkedIn
