Genesis® Artist Colors (Cont'd)
U.S. Patent 5,700,858. Patent pending worldwide.
Drying boxes are excellent because air circulates inside the box and produces an ambient heat. Current models of drying boxes hold paintings as large as 24"x 24".
Place the painting on stilts or put four pieces of wood on the corners. This helps circulate the heat underneath the painting. Set the heat and fan on high. Heat for 15 to 20 minutes. When drying a large painting, make sure the substrate will withstand the heat. Use good quality canvas board with a strong backing. Some canvas board withstands the heat, but tends to buckle or twist when a large piece is heated. Gesso hard board, made of a hard masonite support and stretched canvas, works very well. Because of the hot air circulation, stretched canvas will dry evenly even where the canvas covers the wooden frame.
Adhesive thermometers can be used to measure the temperature of your painting when you are drying with any source of heat. By sticking these on to the back of your canvas, you can be sure the proper temperature is achieved. More dense surfaces might require experimentation to find the best position of temperature indicators.
One source of non-reversible temperature indicators is: Paper Thermometer Company, P.O. Box 129, Greenfield, NH 03047.
These non-reusable strips change color to indicate the temperature reached. They can be used several times by taking the temperature to 250ºF/121ºC during the first heating, to260ºF/127ºC during the second heating, and so on. Some artists also cut the strips in half to use them twice. A useful range is the TL-8-250 that measures temperatures between 250ºF/121ºC and 320ºF/160ºC, or Set No. 4 that measures between 240ºF/116ºC and 280ºF/138ºC.
Store Genesis® Artist Colors away from heat sources. Do not store in the trunk of a car or in places where temperatures could reach 100°F/38°C or greater for a sustained period of time.
Genesis® Artist Colors wont dry when left in the open on a non-porous surface. Use a glass or other non-porous surface such as china, polished marble or porcelain for your palette. The recommended mixing surface is 1/4-inch glass. Some of the ingredients in Genesis® Artist Colors have an affinity for wax and plastic and will migrate into these or other porous surfaces such as wood, leaving the pigment dry and difficult to work. If this happens, remedy by adding Genesis Thinning Medium or Genesis Glazing Medium.
After mixing a color you like, you dont need to keep air away to prevent drying, although you should protect it from dust as you would any wet paint. Use clean glass jars for this. Do not cover Genesis® Artist Colors with plastic wraps because some of the ingredients may migrate from the paint to the plastic if they touch.
Mixing Genesis® Artist Colors with solvents commonly used for oil paints is not recommended. However, if you use solvents, remember to protect yourself and follow the directions including the use of protective clothing such as gloves. Genesis® Artist Colors are not water soluble for mixing and thinning.
This is important, so we repeat: Genesis® Artist Colors are not intended to be mixed with other paints such as oils or acrylics or with water. Other mediums have a very different chemistry than Genesis® Artist Colors and results can be unpredictable.
