Welcome to the Grumble, Kra - an auspicious first post - complete with a photo!

Nice layout of the arrowheads, dare I ask how you attached them to the backing???
 
Kra, you might want to do a search on the main Grumble forum on the word "silicone" or even "arrowheads." You will get an eyeful!

Silicone is our dirty little secret!

i am letting it cure for a few days before covering with glass to let the ascetic acid outgass
i hope i will not have any problems
i thought silicon was pretty much inert once fully cured
i guess i was wrong
thanks
 
Among other things clear silicon is used for making all glass fish tanks. If it wasn't inert when dry it would kill the fish and it dosn't.

I think its biggest problem is it is not reversible.

I suspect more framers use it than care to admit it
 
I did a job recently of 80 (!) arrowheads in a frame. About halfway through I passionately wished that I were ignorant of recent progress in the framing world and could silicone those puppies down! But [sigh] I Mylar stripped each one. Customer LOVED it! But then, he brought it back because the plaque had his name spelled wrong. Some days...
 
Welcome to the Grumble. I've done quite a few arrowhead jobs now and I have had great luck with Tacky Glue. Some are pretty big including some large spear points. One display hangs in my shop. Never have had a problem. I did however fix one arrowhead framing job that a guy had done out west. Fairly small heads, but 5 (out of 50 or so) had came loose. They were done with silicone, but the framer didn't use much of it. Probably why they came loose. I'm sure yours will be fine if you used enough. Looks like you did a great job.

Welcome to the Grumble Randy!.

Nice job!!

If it is a permanent job, I would use silicone in a heartbeat. It is the best for heavy, permanent objects (you could use it for a sizable piece of rock too!).

Other glues become brittle with age and temperature fluctuations; silicone is much more resistant, assuming you use enough and let it dry completely.
 
If I remember correctly, the great Silicone Debate of 2005 is how we grew to know and love our sweet grumbler Mecianne.

We haven't had such a lively discussion about it since. This one is vewy, vewy tame. Of course, all bets are off when some G'ers emerge from behind their snowblowers.

Nice job, Kra (initials?)- and welcome to the Grumble!
 
Silicone is reversable on some things, isn't it? (I said some things!) Holds well, but will peel right off if needed. I've used it for arrowheads and rocks too. Never had one fall off, but able to get it off later if I needed to. I know, I know...but sometimes you just hafta!
Good point about the fish tanks, Mick.
I never knew it was "bad" until I came started Grumbling.

I suspect your statement is true
. I, however, will never ever ever use the "S" word on the Grumble ever ever again. It only takes one good thrashing to learn to keep some comments to yourself

Mick, the Silicon that aquariums use is GE 830 or 850. [Acrylic or Glass] both of those, and only those, are "Food Grade". All the others are Benzine and tetracloribetrobatedhydricarbonated and will continue to off-gass as long as they are plyable.

A conservator brought in a bottle that is about 150+ year old.... and said "go ahead and use PVA".... I'm more of a belt and suspenders kind of guy... there will be mylar staps as well.

Rocks.... PVA or Tacky Glue . . . PVA wants 72hours to truly set up.
 
ok
so what is the worst thing that will eventually happen to these "artifacts"(around here arrowheads are a dime a dozen so to speak.I have given away shoeboxes of them over the years)

Your dog will run off, your truck will die, your six ex's will show up with suitcases at the same time as your current (today's) girl friend walks out pregnant with your brother/uncle/step-father and the IRS is on the phone telling you about the raid on . . .

Oops, just noticed you are in NORTH Carolina... sorry. Ignor the above.

Noxous gas that will smutz your interior package.
 
so what is the worst thing that will eventually happen to these "artifacts"
1. Depending on the nature of the object, the silicone adhesive can etch into it. It might be very slight, but it can be enough to damage and discolor the surface. Think things like old silverware, medals, coins, ceramic.

2. When the object is later removed, it's pretty rare that the silicone just peels off like everyone seems to think it will. It always takes some effort at scraping it off, which could easily damage the object.

3. If the object is porous the silicone will permeate into it. Even if you can scrape it all off the surface, it will still be in the object, probably never to be removed.

4. If it's flakey, for lack of a better word, the adhesion of the silicone can pull layers of it off, either when it's removed from the shadowbox or if it's bumped too hard.

5. Finally, and this is true of all adhesives, you're relying on the strength of the top layer of the mat. Usually if an object falls in a shadowbox you'll find that the glue held, but everything peeled away from the mat.


Just a few things to consider, I'm not the Framing Police or the ultimate authority by any means.
 
Oh my....I was almost afraid to peek into this thread.

GumboGirl, what an entrance I made last year. Whew, if only I'd known! ;)

BTW, I still use silly-cone sometimes.
And like someone said above, I think more use it than care to admit it.

Kra, if you see Emibub coming, duck!! She's a sweet lady, but man, does she hate silly-cone!

Welcome to the G!!!!
 
Silicone is just a tool. As with any tool, you need to know how to use it. It seems to me that you may have used it correctly in this case.

Welcome to the G.

Carry on.
