how to make blast mark

Post by kosherbacon »

this is kinda fun.....my sister recently went off to college and i got to move in to her room \:D/
anyway the light switch plate is a fariy thing, i cant have that im my room. so we got a new one, a totaly blank slate to think about. so i had the idea that i could paint a blast mark on it radiating from the center the only problem is i dont know how to make one. i had the idea that if i make the outline with sticky notes or something and then airbrush it so its darker in the middle and lighter at the edges that that might work but i dont know.
any ideas from you people would be greatly appreciated

thanks

Try drawing it out on a piece of paper first. Draw several different styles, until you're satisfied with the look. Spend some time browsing thru the readers gallery here. When you find a picture of a blast mark you like, copy it, see what makes it work.

Short the switch out to ground with a piece of old wire. Nothing beats the real thing!


ok, ok, I'm only kidding :roll:

Pasels and charcoal are a great way to do it. Don't go too dark. Start light and add more as you need. Artists charcoal can be ground onto paper, use a soft brush to pick some up and deposit on the wall. Once you get a light area, use a little - A LITTLE MIST COAT - spray lacquer to fix it. Then add more toward the center making it darker.

If you go a little overboard, use the kneaded eraser to remove some.

i assume (even tho we all know what happens when you assume)that you would do this after you taped out the edges. right?

I wouldn't tape the edges. Blast marks result from an inherently chaotic event - and stark lines would not be seen. Using the big soft brush to apply the charcoal seems the most realistic method to me. Right up at the crater, you might want to replicate scorching.

Again, like Ter said, with pastels. The center, direct hit area, would be darker than the rest, nearly black. Draw the brush away from the center. Give it a shot. Get it? A shot? Heh heh, hoo wee...

Not to brag on myself, but mine turn out pretty well usually. What I do is load a cotton swap up with dark grey or black pastel and place it, nose down on the model.

Then, I spin it as though it were a drill bit trying to bore into the model. I figure which direction the offending event came from, and then I pull the blast away from it in straight lines; the longest marks continue alog the path of the event. Shorter marks continue around ther radius of the mark until they reach the "backside" of the blast where they're at their shortest. Combine this effect with some surface damage for a really dramatic result.

Blow away the excess powder as you do this. You should be left with a nasty black ulcer and a very realistic burn pattern. I got the idea from watching micrometeorite impact test on ballistic cloth in college and recording the blast patterns.

I hope this helps.

A cool effect is burning from a vent or panel line - if there's a reason for the smoke and ash to be blown one way. YOu can use a post-it to keep an area clean and draw back from there - this is also how you get the grime trails on aircraft etc.

And remember, start light - you can always go darker.

And all the pastel effects we mention work best with a matte finish, not gloss.

Panel lines - gloss. Grime, flat.

Yep, that's just about perfect. I like the paint chips too.
