The True Cross/ Graphic Art


St. Helena( mother of Constantine) found all three crosses buried in the ground, but wasn’t sure which one belonged to Jesus. There are many different legends about how St. Helena and the bishop of Jerusalem confirmed which one was the True Cross. One myth claims the bishop of Jerusalem had an ill woman touch all three crosses. As soon as the woman touched the True Cross, she was healed.

Bornyl Acetate In Oil Paint Dilution Artwork

 A commercial oil paint is diluted with bornyl acetate. The latter is used in foods and in preparation of air fresheners. I convert turpentine into bornyl acetate with glacial acetic acid and an Amberlyst ion-exchange resin ( 70 deg. 6-7 hrs). As an organic solvent, turpentine , producing a pungent vapor ,can irritate the skin and eyes, damage the lungs and respiratory system, as well as the central nervous system when inhaled, and cause damage to the renal system when ingested, among other things. Ingestion can cause burning sensations, abdominal pain, nausea, vomiting, confusion, convulsions, diarrhea, tachycardia, unconsciousness, respiratory failure, and death.

The Occupational Safety and Health Administration (OSHA) has set the legal limit (permissible exposure limit) for turpentine exposure in the workplace as 100 ppm (560 mg/m3) over an 8-hour workday. The same threshold was adopted by the National Institute for Occupational Safety and Health (NIOSH) as the recommended exposure limit (REL). At levels of 8000 ppm (4,448 mg/m3), turpentine is immediately dangerous to life and health.

Tempestuous Blue Paint Formulation


I mix calcium hydroxide ( lime) with water, ammonium zeolite ( SiO2/ Al2O3) , finely-ground blue sidewalk chalk and catechol violet dye. Additional water can be added to retard plaster formation. Here , it is applied with different brushes and dilution to sketch paper and cardstock.
