Are you using boro?
I think it only works on soft glass.

etch all wont touch boro, unless you want a petrol finish on the surface rather than a sandblasted look!

[dnug42]

what...oh man- no one told that...i ordered a bunch of boro when i got it, and was asking all kinds of questions about it- i guess they did not put together the two...oh well glad i asked before i opened...thanks...return...so can you only sandblast boro? i cant belive every ground joint is sand blasted.....

[Mecha]

Ground joints are ground, not sand blasted.


Unless you are sinbad that is.....

etch all will work on boro. you have to ignore the directions bc they are for soft glass.

let it the cream sit for 24-48 hrs on boro and it will do the job

i heard hydroflouric acid works for boro

[Mecha]

HF acid will completely eat through quartz, much less boro. Not to mention the fact that it is EXTREMELY dangerous and should only be used in the proper environment and with the appropriate safety equipment.

For the amount of money you would need to invest to use HF responsibly, you could easily pay for a blasting setup.

but it also depends on how diluted it is

but it also depends on how diluted it is

Even diluted it is still extremely dangerous, and an environmental hazard. I used to work with it on a daily basis. I would never recommend its usage unless absolutely necessary. Giving art glass a "frosted" appearance hardly justifies its usage.

[full_kiln]

true, damn man, what did you used to use it for?

[Mecha]

Mainly to remove the haze you can get on worked quartz pieces. It was also used to prep certain jobs. It works really well at cleaning the scuzz off of a cut tube so that you can get a nice clean weld.
For a few jobs it was actually used to remove the slightest amount of material so that a piece would be in tolerance. It is some pretty serious stuff for sure.

Etch all works great for removing dichroic coatings.

I tried to Etch-All the back side of a Boro marble - left the stuff on for 3 days and all it did was to dull the glass - slightly!

hey santa, was the brand "armour etch" or "etch all"?

i've used the armour etch before on clear boro, and it worked....sorry

[mer]

etching cream might not eat boro but it does take silver/gold/dichro off of the surface nicely. you can get some cool effects this way. definitely handle with care though, extremely toxic.

[richsantaclaus]

It is Etch all and I put it on the colored glass on the back of the marble

[kage]

well my experiment was about 6 yrs ago and my memory is a lil fuzzy, so i am sorry if i lead anyone in the wrong direction. i am going to figure this out. all i can remember is that i caked the armour etch on....several coats....it was just a couple of beads but it they had a blasted look to them. i left the lid off or something and it dried up before i got to use it again. shortly after that i have had access to a real sandblaster ever since.

i don't want anyone to think i am trying to mislead them or give false advise.

[obscure_shadow]

i used some stuff called etch-all to take off the scuzz from some dark turquoise 104 glass, but i have no idea what it would do to boro..

Ive got a clear marble sat in etch all(brand), been in it all weekend, nochage still looks petroly maybe its down to the brand, im using schott duran clear at the moment
