Firescoff


#1

Does anyone know about firescoff. Whats in it? Or is there a
comparable substance? The product is very expensive! M

I have used it in the UK and

you’re right it is VERY expensive. I’ve found it needs several
squirts to get proper even coverage and the overspray wastage onto
the soldering block is, at the price you pay for the product, truly
grievous.

I didn’t think the results were any better than using a boric acid
based protector (branded ‘Argo-Tect’ over here - no affiliation!)
mixed with water and detergent (dish soap).

However the latter method, though cheap and effective, can make a
mess of the soldering block after a while.

Enjoy.

I used Firescofff this week on a few projects. Very pleasing results
on sterling silver. No fire scale or fire stain, did not need to use
pickle. I do not use the spray, but patted it on with an almost dry
brush just to get a frosted appearance on the metal.

Maryfrances- We make our own. It’s just powdered boric acid mixed
half and half with denatured alcohol.

You can buy the boric acid powder from most jewelry supply places.
Borax works for casting but no this. You need the fine powdered
stuff. The denatured alcohol I get at Home Depot or any hardware
store. It’s in the painting dept. We buy it by the gallon.

It must be denatured alcohol. Rubbing or Isopropyl will NOT do.

Just mix together in a small jar and dunk your work in it before
soldering. Keep the lid on the jar at all times. If you accidentally
set it on fire, and believe me you will at some point, don’t panic.
Just put the lid back on as quickly as possible and it will smother
out.

Every one has their preferences of one product or another, but home
made works for us. I also always make my own glass cleaner rather
than pay a stupid amount of money for windex. I grew up in a house
with a chemist, so I have no fear of chemicals.

Have fun and make lots of jewelry.

Hi,

I have read that it contains aluminum chloride, which is an
important part of the anti-transpirant. Try a spay with
anti-transpirant.

Hans Hansson, Sweden

Aluminium Chlorohydrate is a chemically synthesised active
ingredient in Anti-transpirants. It clogs the ducts of sweat
glands and thus reduces sweat secretion. Furthermore Aluminium
Chlorohydrate exerts antibacterial effects. 

Aqua, Aluminiumklorhydrat, PPG-15 Stearyl Ether, Steareth-21,
Steareth-2, Ethylhexyl Cocoate, Trisodium EDTA, Parfum. 

Aluminium Chlorohydrate act on the eccrine and apocrine sweat
glands by partially and reversibly clogging the duct of the sweat
gland thus rqeducing the amount of sweat that's produced. Because
there's less sweat, there's less dampness and noticeably less
odour. Even small quantities of anti-transpirants suffice to
effectively reduce sweating.

I manufacture Cupronil and sell it to Rio Grande, Indian Jewelers
Supply and Thunderbird Supply and various other suppliers.

Cupronil is a liquid flux that is sprayed on slightly warm metal. It
willprevent fire scale when it is used as a coating during the
soldering process.

Heat the metal slightly. Spray Cupronil on the warm metal. Cupronil
willform a coating on the metal if the metal temperature is correct.
If the metal is too cold Cupronil will puddle on the surface.

Coat all surfaced of the metal before doing any soldering.
