Default Etching 90 or 96 Coe

I know,that 90 and 96 don't etch with the normal etching solution so I purchased a tumbler. The silicon carbide I use causes a real mess and I'm afraid some will get in the drain pipes. Is there something else that can be used instead of it? There are so many colors in these COEs I'd love to see etched. Thanks in advance!

I etch 96 COE all the time and never had any problems. Furnace glass frit, Uroboros, Spectrum 96, all of them etch well with Dip n' Etch.

REALLY?? I always heard 90 & 96 didn't work with etch all. Great to know...I'll give it a try. NOW how about 90????? Someone's gotta have a better way that that gritty, messy silicon stuff!

Boro (33COE) doesn't etch. 90 & 96 etch just fine.

Yes. Tumbling gives a softer finish, but doesn't get in all the cracks & crevices.

Well, I have no idea where I got the idea that the cream and liquid only worked on 104?!? Im so glad I asked the question .... My life just got a lot easier. Thanks everyone!

I'm curious about your tumbling. I haven't found it all that messy, just a little bit of a pain to scoop out the beads when they're done. I think I'm going to get a slotted spoon to make it easier. Are you using the tablespoon or so of silicone carbide that I had read to use?

I'm sure I've used too much. I have added some each time I use it. Probably operator error on my part. Think I'll dump it all and start over. I also use some little blue hard material I read about in a thread here...about 8 or 9mm each. Forget what it's called.

In my tumbler I use playground sand I bought at home depot. I also use broken bottle glass and a bit of silicone carbide. The bigger broken glass pushes the slush around more for quicker etching.

Tumbling is a bit easier then chemical etching, fewer noxious chemicals.
Not to mention being handy to polish findings and make faux beach glass.

To make things easier try threading the beads on a piece of spider wire or fly line backing.
The woven fishing line should keep things together and make retreaval easy.

I'm planning on doing that next time now, thanks for the idea!

I had limited success with etching Bullseye with the etching liquid. Some colors fine, some colors not so fine.

I still have my liquid etch but I mostly use the tumbler now. I use Caribbean Reef gravel/sand from the pet store or 120/220 silicon carbide grit ... depending on satin or more robust.

Which give the more satin finish? and is your silicon carbide look like small pieces of black sand?

My 1000 is more like dark grey powder, very fine.

I find that some BE glass will etch, but a lot of it won't, and it takes longer than 104 glass

Anytime I put sand or silicon carbide into my tumbler, it leaks. I thought it might be my barrel so I bought a brand new one and it did the same thing. I have no issues when I'm using stainless steel shot for tumbling metal.

And your point is??? I read ALL the threads about etching and know it's toxic but as a grown up I can make up my own mind as to whether to use it or not. And ... leave the poor horse out of this!

It's more like silt ... think GAs finest frit above powder (82 mesh) and that's what I would consider it.

It gives a very soft, satin finish. But it doesn't get into the grooves very well. But most of what I etch isn't real textural and if it is ... I still have the wicked chemical to try.

I bought it at Kinsley North (by the pound) ... I couldn't decide what grind and after reading and reading went with the 120/220 blend.

I use it with the plastic pellets Kinsley also sells. Dump everything in the barrel ... close it up and let it spin for a day or two ... check ... repeat if I'm not happy with the level of etch.

Warning ... the satin finish is very soft and will not really show on the wet bead ... you have to let it dry to get a good feel for just how "etched" it has become.

If you would like to try the Reef Mix (I bought a lifetimes worth) I can send you some. Though it will give you the faster, rougher etch. Also have Thumber's fine (I think its around 1000 grit) that I'm not using.

Make sure to wipe any residue from around the seal area of the tumbler. Likely there is sand or silicone stuck in there that is breaking the seal.

Yes but there are still many that DON'T and think the shit is safe simply because it is sold at the hobby shop!

Yeah, that's my problem as I'm not wiping, just sticking the lid back on. Thanks!!
