Has anyone sand blast a shale before??? If you did, has does it turn out? Any advice would be great... I hear it won't last as long as sand stone...
Thanks... Letterhead Rules!!!

Not sure what you actually want to know about 'how it turns out' but;
Plenty of stone flows through here. Right now, I literally have a boulder sitting in my workshop! The label says it's Ozark Moss. Never seen it before, but we're gonna blast it!
As for 'what you get' after blasting; Shadows...
Depending on the effect the client is looking for, the blasted areas may need some paint, to pop off.
Know your blaster...

Is shale similar to slate? If so, we have some people right here in Letterville that have all sorts of experience. Contact Mike at http://www.signsfromabove.com

Jaime If its what I think it is. I've blasted them. It was by request of the customer. He ownes this golf course. I blasted 23 granite & sandstone boulders for his T-box signs & some directional signs, which went well. Then he wanted the name blasted in this huge 10 ton boulder sitting on the corner of the development. It was shale. I would charge xtra for the headaches it causes but it can be done. How big of a shale are you working with?

There is a wonderful artist in Dingle Ireland that does nothing but "slate" sandblasting she uses the old slate shingles that abound there.
Her work is wonderful and I'm looking for info on her as I type...you might want to go into Google or ask jeeves and check for Dingle Ireland then check out the arts section.
If I find more info I'll post back...

Thanks for the advice... The shale is kinda like slate... The size I got here to work on is 30" x 33" stone... I guess I could give a try to how it looks... I'm going to have to sample one first before doing the actual one. So I don't waste the materials, if it doesn't work... I'll check on the Dingle Ireland... And see what kind of work she does...
Thanks Letterhead...

Hi, apologies for not responding sooner. Steve sent me an e-mail about your query but my e-mail server was down and I just got the message today.
Shale is virtually the same chemical composition as slate. While slate is 400 - 600 million years old, shale is much younger and, as a consequence, not as uniform or as hard as slate. Both blast about the same but the shale is not as durable or as predicable. If you intend to engrave or etch rather than blast I would suggest that the shale might not be too permanent ie.) <20 years. If you are going to blast, avoid going too deep as the letter centers will have a tendancy to chip off. You migth want to spray the stone with Krylon 1301 clear. A light coat will help seal the stone for application of the blast mask. The 1301 will fade away soon after UV exposure.
We do not use silica to do any blasting. We use aluminium oxide which is much harder and can be recycled 15 - 20 times when blasting slate or simlilar soft stone. Density of shale varies greatly but you should find it uses slightly more blast material than sandstone.
If you would like to see what we've done with slate, you are welcome to check out our new "under development site". It is not for public viewing yet and is only visible at it's temporary location www.signsabove.com It's probably best to go through the site map as the pages change all the time.
Hope this info was of some help. If we can be of any other assistance feel free to give us a call at 1-888-427-7446.
