Please check the Frequently Asked Questions before writing, as I receive too much mail to reply to questions which are answered there.  I regret the necessity, but I hope you'd prefer that I make more art rather than answer more mail.

I'd like to use pictures of your work. You used to have X for sale, when will it be back? Can you make very large glass pieces? How do I clean your sculptures? Will you help me make something? How do I start making things like yours? Can you recommend a course of study? How can I stay in touch? I'm writing an essay, tell me something about what you do. I'd like to use pictures of your work. That's fine, as long as they're accompanied by my name ("Bathsheba Grossman") and if they're online a link to www.bathsheba.com.  If you need high-resolution images suitable for printing, just ask. If you'd like to use a 3D design for any purpose, please ask.  I've licensed models for many uses, and I'll most likely be happy to help with yours.  I like to collaborate. Please don't use images without credit.  Don't use or reverse engineer any of my 3D objects without permission.  Doing these things violates copyright law, and also makes me unwilling to work with you.  Please contact me instead, and most likely we can arrange what you want.  I'm usually happy for my designs to be used, just ask first. You used to have X for sale, when will it be back? I don't know.  When I take something off the site (such as jewelry) it's because I've run into problems making it with good quality for a reasonable price.  I'll bring it back when evolving technology, or other changes in the resources available to me, make it possible again.  As soon as that happens I'll announce it on the News page, but before then I don't know. Can you make very large laser-glass pieces? I don't do this for several reasons.  First, no etching laser that I know of can fire more than 3" into glass, so that's the maximum depth I can etch.  Second, large glass blanks are very expensive.  The largest piece I've worked on is a 26" square by 4" deep galaxy design, and the blank for that cost over $10,000.  Generally it is a lot of work to generate quotes for projects of this type, and once quoted they are usually declined because of cost. How do I clean your sculptures? Metal These are shipped oiled to protect the surface from chemical attack, and I recommend keeping a little light oil on them, as you would any metal tool: 3-in-1 or light motor oil is fine.  If one gets dirty, wash and re-oil.  If one rusts – this is rare, but it can happen in wet or corrosive environments – use rust stripper then re-oil.  I like Jasco Metal Etch, but anything with phosphoric acid should work. Glass Any general glass cleaner should work to remove crud.  To avoid scratches, I do recommend using the rubber feet: they prevent grit under the piece from scratching it.  If a piece does get scratched, it's possible to buff out small scratches with Brasso or any mild abrasive (Google has lots of advice on this) and elbow grease.  If that's too much work, a little Pledge or other furniture polish can do wonders to hide scratches. Will you help me make something? If it's a laser-etched molecule, please visit Crystalprotein.com. If it's something else laser-etched in glass, bear in mind that I work only on scientific imaging projects.  I don't etch cars, buildings, portraiture, or photos.  Laser Crystal Awards may be able to help with these types of project. In general, I'll work on an outside idea only if I love it and it fits with what I do.  In this case my next question will be whether you'd wish the design to become part of my catalog on this site, naturally with credit to yourself.  How can I start making things like yours? Think of something to begin with – the first one can be simple – and get busy!  You'll need to draw, generate, scan, or otherwise acquire some 3D data that describes your subject.  Some tools that might help are here, and never forget that Google is your friend.  Then you'll need a fabricator, or a 3D printing facility, or a laser etching facility to make the object; or maybe you can make it yourself.  If you want to try 3D printing, your first decision will be which machine to use, as they all do different things.  A lot of useful information is here. Now you know much more than I did when I started.  I wish you good luck, and if you make something nifty, I'd love to hear about it. Can you recommend a course of study to get into your field? Not specifically.  I recommend doing what you like, learning about what interests you, and going where it takes you.  My path led through a math degree, an art degree, and many years working as a programmer.  Maybe that was overkill, but I think it's worth noting that I didn't do those things with digital sculpture in mind: most of the technology I use now didn't exist then, so there was no way to know what would be useful.  The future's going to be even more unpredictable, so I think it's best to follow your nose: do what you like in a serious way, and stay loose.  And make sure to have a day job lined up.  There's nothing wrong with a good day job, and you're likely to need one.  I worked as a programmer for 15 years. Regarding CAD modeling and 3D manufacturing I'm self-taught, so there I can't recommend any educational method, other than to download some tools and get started. I'm writing a report, tell me something about what you do. Just about everything I have to say about it is already on this site.  There's a list of meaty pages here.  If you have a particular question that isn't answered in any of these places, then go ahead and ask.  How can I stay in touch? For online updates, this page has an RSS feed. If you have a stable address and would like to get postcards, you can sign up here.      These are physical snail-mail postcards which I send out very occasionally; not as often as once a year.  Naturally I do not share or sell addresses or emails.
