The hardware store only had transparent yellow epoxy. Locktite. .
Since the glue is hidden between rocks, and if any that squished out would be wiped away immediately, why does it matter that the epoxy be clear?
Thanks.

Sneaky. How can you tell if it yellows with age? : )

I save dust from grinding various stones and mix the dust in the epoxy for fill to help blend better with the stone.

One that I know won't yellow with age for sure is Epoxy 330. Buy the smallest tubes you can because it does have a shelf life if you don't use a lot of it all the time. Any jewelry supply will have it as well as Amazon, etc.

hummingbirdstones re shelf life: it is my understanding that the glue goes bad because air gets through the plastic lid. I've been keeping my glue in glass jars. Put kitty litter in the jar to absorb the air. Seems to work.

Thanks, Pat, sounds like a good idea. I'll have to try it. |

Hi Pat, The 330 Epoxy is the most popular amongst lapidary and craft folks but I honestly couldn’t say it was significantly better for our (Intarsia) purposes. It certainly appears to be the most expensive. I have used several brands of clear 5-min clear epoxy in classes and on my own over the years and never had issues with any of them. Therefore being basically a thrifty feller (i.e. cheap) I usually opt for the least expensive. I’ve had good luck with the small tubes of Harbor Freight clear 5-min epoxy item# 92665. I think it retails for under 2 bucks and frequently I’ve gotten it on sale for less.
Adding “matching” dust to epoxy is a good trick for blending seams particularly if your seams have irregularities or undercutting. Along these lines, you can also add colorants to epoxy. There are colorants specifically made to use with epoxies but I’ve had good luck with India ink. For example, I frequently back my pieces with black (basenite, basalt, jade, etc) and if I’m having trouble getting the back of the intarsia and/or the backing piece absolutely flat prior to glueing, then I’ll add a drop of India ink to the epoxy mix. This disguises any seam irregularities. Note that adding any liquid to epoxy thins it out a bit and usually lengthens the curing time but not significantly and you can always speed the cure with some heat such as under an incandescent light.
Haven’t quite figured out how to add pictures...🤔

This is a fascinating forum and I’ve enjoyed all of the posts. Many thanks to everyone👍. I was particularly interested in the attachment that sits on top of the Ameritool grinder. Very ingenious but then again so is the chunk of wood with grooves in it... I like the idea of the “whatever works” philosophy. I use an Al Sesona grinder but years ago learned to do Intarsia by just holding the piece on the flat lap. With a bit of practice one can get quite good and after all no one had fancy right angle grinders to create those breathtaking pieces in museums. BTW there are two videos available (Basic and Intricate Intarsia) by Intarsia Master Phil Magistro. He demonstrates “Basic” using just a flat lap and a faceting machine for the “Intricate”.

Thanks, berfle I just emailed Al. There is very little on the web on stone intarsia. Will check out the video on metalsmithing, too. |

You’re right Pat there’s very little out there on Stone Intarsia. Don’t know if you’ve seen these or not: |

DISK UPDATE: Al tells me that it doesn't look good getting those two disks, so he says he has removed them from his list of available products. I've asked him what else does he have that I might like since he has my $100! Hope he has something!
I am ordering the two dvd combo sets --- intarsia set and silversmith set.
