Stains and Flourescent lights

Question for the group. For years I have used variations of the india ink/alcohol mixture, as well as Silverwood and other commercial stains to represent unpainted wood. The effects are as desired when treated, but I notice that after a while under flourescent lights the wood gets lighter and lighter, until it looks untreated. Anybody else noticed this, and come up with a solution to the problem, or should I be using another technique. TIA

Flourescent lights put out more UV than incandescents, UV light tends to be harsher on dyes.   I believe you can purchase a UV filter, which might help.  Personally I prefer incandescents, they more resemble sunlight, and can be dimmed nicely.

I have noted the same thing as Younger, but my model room is lit by incandescents, and still stains and washes fade out over time.  No solutions from me either, sorry.

I think the solution is to keep building new models!
May be this is why so many railroads get torn down after being finished?
Sorry I am of no help either.

Jerry,

Maybe try using acrylic washes like Doug Ramos does....or "working wet" with acrylics like Per Olav Lund does.

I have for the most part moved away from the silverwood (and was never a fan of the IA)....as I feel the acrylics give you a far better range of color and and hue, and the finish is more opaque...thus resulting in a more realistic appearance Iespecially once you get into the 1/32 stuff you're doing). I belive the acrylics will give you more lasting color permanance......plus its more fun stuff to buy. ;D

Why not see if Doug will do a small cliinic/demo at the next meet.

Marc beat me to that suggestion. It seems to be about the only alternative. -- Russ

Thanks, guys, I'll see if I can get some info from Doug.

Unless I'm mistaken, Doug's info, step-by-step, is in the current Narrow Gauge Annual. -- Russ

I have flourescent lights in my workshop where I have a large 1:20.3 diorama I have been building for a few years.  I used Silverwood in a couple of places and noticed after one year the wood almost bleached out.  I re-coated with Silverwood again and by year two, almost the same result.  I never thought about the cause being attributed to the lighting. Inever really liked the results of Silverwood or black ink/alcohol dyes mostly because there is no color variation.  I'm glad i did all of my other wood treatments with acrylic paints.  This winter I plan to work with oil based washes and see if i get better results.

I only made the observation, that these special energy saving fluorescent illuminants/bulbs let stained parts of a modell appear in quite a different (greenish) colour compared to daylight, while taking photos of it ...

BTW: I'm not trying to be more Catholic than the Pope or a nitpicker, but I'm curious if "flourescent" is the american spelling of "fluorescent" ... or in this case simply a misspelling ...   ???

finescalerr

It is a misspelling.

Fluorescent bulbs come in different color temperatures. By choosing, for example, 9300K bulbs you should see no "green" tint.

Isn't true color (or as close to natural light) somewhere around 5000-5300K?

Gerald,
When shooting photos in flouresc. you can get rid of any discoloration/tint, by manually pre-setting your "white balance" on the camera.

I think that as more people switch to fluorescents, by choice or by mandate, they're going to discover a lot of things in their homes becoming faded or damaged by UV.
