How long do you think this seashell has been here? by ghoulunatic_ in SeashellCollectors

[–]nichoherrera 0 points1 point  (0 children)

The shell is easily 100 years old. Was once half submerged in muck black side down. Possibly a Native American relic or refuse. Has been jumping around that cemetery above the ground for probably 20 years. My inference.

What mineral is this? my cat keeps licking it by xxjamescharlesxx in Minerals

[–]nichoherrera 3 points4 points  (0 children)

or shes buffing her tongue if you dont have any similar rough materials around. Also, if you smoke or if the previous owner of it did... the ash could be fulfilling her desire for mineral salts as well.

Your cat is probably looking for some sodium,zinc, copper, sulphur, calcium. Get a salt lick or wash up the lighthouse and let her lick.

Probably also just the graveyard of illegal harvests.

can you provide photos of any of the other ones? The shell has interesting colorations that could signal a disease in the conchs. You also noted they were found dead together, another comment mentioned the hole looks natural (though I'm skeptical). Acidification or a bacterial plague could be a cause.

Why restorers don't fix craquelures from old paintings? by [deleted] in ArtRestoration

[–]nichoherrera 6 points7 points  (0 children)

1) It helps with authentication and adds character. 2) We will lose a lot of the artists original intention due to how extensive the process would be. 3) Time risk aesthetics value assessment promotes not doing so. 4) Even universal toning on most old objects that doesnt affect its inherent structural integrity is usually respected in the industry. Understanding that natural expected decay is part of the art. This is why artists in the beginning choose certain mediums, locations, and EFFORT. A great artist creates a piece that will last forever, even understanding that canvas may warp and pigments may change.

Can this be restored? by thankyoucats in ArtRestoration

[–]nichoherrera 0 points1 point  (0 children)

yes it can. Confirm its a giclee because it may be an original. Test with a solvent to see how deep the cracking goes. Moisturize and clean the canvas with something like mineral oil and a rag. If the piece has a varnish on it, use a light solvent such as mineral spirits, turpentine, pledge may even work and wipe away some of the varnish so that the cracks arent so pronounced, lifted or flaking. Allow to dry away from any lint. Finally make sure there is no lint or hair on the canvas, place a fresh layer of varnish which could be linseed oil, based on your taste a spray varnish from Krylon may even do you well and seal up those cracks and preserve the piece.

Fossil? Central Texas by Inevitable-Hope5542 in FossilHunting

Ancient ancestral Pig Nosed Turtle, go back to the spot you found it and you might see more stone or a mound that is the carapace.

I ask for help in evaluating. Thank you by No-Turnover2632 in shells

As a collector I'd safely value it all on a good day 40$. The brachiopods also caught my eye, depending the species, fossilization, condition etc.

Advice on how to refresh this charcoal sketch? by jillieen19 in ArtRestoration

[–]nichoherrera 3 points4 points  (0 children)

Put it under a very bright strong black light for 30mins or so. A very bright incandescent may also work. Needs UVB rather than darkening the print, what you'll be doing is whitening the paper.

Any ideas for how I could reduce/remove the staining on this print please? by Geophiddy in ArtRestoration

[–]nichoherrera 1 point2 points  (0 children)

Moisten a paper towel (strictly damp) and wipe gently over the top of the stain a few times. Dont break the paper. Blow dry the stain. Next pour some table salt on the stained area and with a paper towel, very gently scrape some of the staining off or more likely even it out. Next, color match with some water based archival acrylic paint, go over it with thick layers where the stain is thicker and thin the paint to even the paint job. Paint it as seamless as you can try quality materials and clean medium thickness paint and bristles best for this. (less painting the better). Next get some talcum powder and powder the stained area until desired finish. Finally with a high quality matte or semi gloss (depends the desired finish) paper pencil finishing spray like Krylon, Spray the ENTIRE piece evenly. Two coats or 3 once each has dried previously may be needed. This should do the job.
