I have used the Rio product, Colores, which is a resin, to paint on
sterling. I have used brushes and for very fine lines, I have used
toothpicks and hat pins. I also use the syringes for mixed colors.
You simply mix the colors in one of the plastic cups that is provided
with Colores then pour it in the syringe.
If you use the paint brush, you need to immediately wash the brush
when finished so it can be used again. I wash first with a simple
green product and then wash with goo gone.
When painting with Colores, the first color must be dry before the
second color is added. Drying time is minimum 36 hours for each color
in areas of high humidity. I have ignored the long drying time and
applied a second color after 12 hours and for certain things the
colors bleed together in an attractive way. However, this is not
always the case.
From an Orchid posting in Sept 2008 the following may help.
Colores is sold in the Rio catalogue. Read the instructions very
carefully. The colors are wonderful! The application is
challenging. It takes time to stir the colors and to mix the color
and the hardner. It takes time to learn to use the bottles with
the syringes. The drying time is minimum 24 hours. On my last piece
I applied a second color after 23 hours and the colors ran together
on the sterling. I am in the process of removing two layers of
Colores and re-reading the instructions. I will be sure I allow 72
hours for drying when I re-apply the Colores. Now that I better
understand the process I like it.
Rio teaches a Colores class occasionally. I took the class in Feb
2005 from Bruce and he was a good teacher. In the class, we practiced
on wax paper. After I bought the kit, Anne Larsen allowed me to use
her studio with five of her students and we “played” with Colores.
Everyone was trying something different. Ideas were flying all over
the room. Someone was always saying " Look at this!" and we all
learned significantly from working around the same table and
reviewing each others experiments.
The positives are fantastic color; non-toxic; clean-up with soap and
water then Goo Gone; you can drill with a flexshaft cleanly through
Colores on sterling; you can wipe the plastic cups clean and use
again; you can knock a mixing cup of Colores off the table onto the
floor and it stays in the cup when it hits the floor.
The negatives are difficult instructions; long drying time often
dependent on weather and humidity; it will finger print at 72 hours
under some conditions; Colores can spill during shipment even though
it appears very tightly closed; difficult to achieve hi lite effect
as it is not possible to duplicate “puffing”; you must work on a
completely level surface or your work can slide; if you use an oven
to dry the first color, you cannot use the oven for a second color
without damaging the color of the first layer; you need color mixing
Hope this helps.
