I wish photobucket hadn’t gotten so greedy, I’d post some of my experiments with textures like superglue and white glue(PVA), Distress Crackle paint, and the rusty stuff. The rusty stuff was the coolest in my opinion, but the bottle of iron pigment solidified and I haven’t found a new place to buy it.

Why not just upload the images as attachments to the post when posting here?

I don’t know how to do that.

I don’t know how to do that. You need to be using the full site. If you're using a mobile browser, there should be an option somewhere to use the full or desktop version of the site. Then you need to click on the "reply" link to go to the full text editor rather than just clicking on "post quick reply". In the full text editor you will see an "add attachment" button. With this you will be able to upload files and embed them in your post. Images will be displayed as a thumbnail link to the full file. If you go to the "bbcode" tab you will be able to set "thumbnail=0" if you wish to turn off the thumbnail. What I like to to is publish a post with an image attachment with no thumbnail, then view the post and open the image in a new tab. Then I copy the image address from the new tab, and go back and edit my post, embedding the full size image into the post by clicking on the image button and pasting the address.

Somewhat disturbing. These compounds are controversial. Thanks for that info.! It's especially informative for you young dudes. Here's a little review related to boron proper: www.ncbi.nlm.nih.gov/pubmed/10050914With healthy skin absorption very low/ negligible (didn't touch it or kick up clouds, in any case) and with my kids already grown, I'm not personally alarmed. I weigh nearly 100 kg so 20-40 mg (per EPA, NAS, and WHO) exposure (ingested/ inhaled) *every day* would be max "with no appreciable risk of adverse health effects". At least according to the reference provided. The document also says "Boric acid and sodium tetraborate decahydrate (borax) are low in toxicity for acute oral exposures. ... The U.S. EPA considers boric acid to be low in acute toxicity based on studies in rats." *For me, trying it on a base is not scary... BUT it looks like frequent occupational exposure - or maybe basing an entire army, managing to kick up clouds whilst biting your nails, over a month or two - might be ill-advised.* Also informative (insofar as Borax is related to the trace mineral Boron), a 1997 "Expert Committee" report by Moore J. stated "Dietary exposure to boron for an adult typically ranges from ranges from 0.25 to 3.1 mg B/d with an average of 1.5 mg B/d ... Individuals who also use body-building supplements may have a total daily boron intake of 7.5 mg" ... Occupational exposure to boron is mainly through inhalation of borate containing dust during mining and manufacturing processes. (Reprod Toxicol. 1997 Jan-Feb;11(1):123-60 www.ncbi.nlm.nih.gov/pubmed/9138630.)Lastly, here's an exerpt from the National Library of Medicine ( www.google.com/search?q=BORAX+-+National+Library+of+Medicine+HSDB+Database&oq=BORAX+-+National+Library+of+Medicine+HSDB+Database&aqs=chrome..69i57j69i60.534j0j9&sourceid=chrome&ie=UTF-8 ): "Boric acid and sodium borates have been considered as being "toxic to reproduction and development", following results of animal studies with high doses. Experimentally, a NOAEL (no observed adverse effect level) of 17.5 mg/kg bw/day has been identified for the (male) reproductive effects of boron in a multigeneration study of rats, and a NOAEL for the developmental effects in rats was identified at 9.6 mg/kg bw/day. These values are being taken as the basis of current EU safety assessments... The present study was conducted to investigate the reproductive effects of boron exposure in workers employed in boric acid production plant in Bandirma, Turkey. In order to characterize the external and internal boron exposures, boron was determined in biological samples (blood, urine, semen), in workplace air, in food, and in water sources. Unfavorable effects of boron exposure on the reproductive toxicity indicators (concentration, motility, morphology of the sperm cells and blood levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and total testosterone) *were not observed*. The mean calculated daily boron exposure (DBE) of the highly exposed group was 14.45 +/- 6.57 (3.32-35.62) mg/day. These human exposures represent worst-case exposure conditions to boric acid/borates in Turkey. These exposure levels are considerably lower than exposures, which have previously led to reproductive effects in experimental animals. In conclusion, this means that *dose levels of boron associated with developmental and reproductive toxic effects in animals are by far not reachable for humans under conditions of normal handling and use*. [Duydu Y et al; Arch Toxicol. 85(6):589-600 (2011)] **PEER REVIEWED** PubMed Abstract www.ncbi.nlm.nih.gov/pubmed/21424392?dopt=Abstract So, yeah... it's controversial... and I'm on the fence. It's in soaps, creams, even dietary supplements! Still, I'm glad I'm moving toward the "Distressed rock candy" paint approach. I'll probably still base and seal a few of my dude-mans with it. Thanks, guys.

Uh, sorry for that wall of text! I'm an academic related to this discipline so I dug a little in my usual databases. Hopefully there's info above so folks can calmly come to their own conclusions.
(And it's not like the crystal basing effect is so stellar anyway.)
