Snow Basing Materials Reference

Inspired by the most recent issue of The Weathering Magazine, I have sought some other solutions for creating snow bases. I had been happy with my techniques, for the most part, but over a few years anything I did with baking soda yellowed. To find something that appeared the way I want and would (hopefully) retain its color over time, I created this reference.

 

High resolution version available here.

The products are fairly easy to get. The Microballoon filler is commonly used to cut resin to make lighter casts, and it is a very fine powder. Try not to kick it into the air and inhale! The Snow Base is part of a Woodland Scenics "Scene-a-rama" set that includes base, snow flock and some icicle making lacquer in a little paint jar (the kind GW includes with their starter paint sets.)


Interestingly enough, some of the samples changed dramatically in the 24 or so hours between creation and this photograph. The Vallejo Foam Snow sample shrunk, and the Woodland Scenics Snow Base cracked and separated more, although the snow base might not have been adequately mixed for that sample. Some of the microballoon samples lost volume as well. 

Overall, I was most pleased with the simple and cheap mixture of PVA and Woodland Scenics Soft Flake Snow, either just mixed together or mixed and topped with more Flake Snow. The PVA + microballoon mix probably looked the most like a fresh fall of snow at a small scale. The simple PVA topped with Flake Snow would make a good frost cover. Some of the later samples were topped with a mixture of Flake Snow and microballoons to see if the surface texture was dramatically different than using just one or the other, but I don't think the results warranted the trouble. The mixture of all the products led to some different textures, and I would assume that those could to roughened/smoothed with the addition of more of the wet component.

  1. Shnow effects are something I've studiously avoided, but I think you've just given me the golden key! Thanks - a very useful reference.

  2. I can vouch that cheap PVA will yellow drastically over time. I wonder if clear acrylic medium would be safer?

  3. Maybe varnish (one that has UV protection) instead of pva would do...

  4. I will never Cheap Archeage Gold consider defeat and I will remove from my vocabulary such words and phrases as quit, cannot, unable, impossible, out of the question, improbable, failure, unworkable, hopeless, and retreat; for they are the words of fools. I will avoid despair but if this disease of the mind should infect me then I will work on in despair. I will toil and I will endure. I will ignore the Archeage Gold obstacles at my feet and keep mine eyes on the goals above my head, for Buy Archeage Gold I know that where dry desert ends, green grass grows.
