EQUIPMENT WHEN TESTING GOLD WITH ACIDS?

The following is my personal opinion.
It has been traditional for many many years, for jewellers to show that they are real jewellers by showing how badly burnt their fingers are, it looks as if they are stained yellow from heavy smoking.
Whilst tiny drops of acid only burn the surface of the skin and cause no other harm (not enough to burn through the skin) and the skin does grow back in a few days - it is not necessary to burn yourself. It should be a matter of pride that you never burn yourself.
So please do buy some of these acid-proof gloves. These are special acid-proof gloves, they are not rubber gloves, and they only cost a few pennies each. We sell these.
Required? Probably not.
I can't actually see how it's possible to splash acid from one of our plastic bottles with a dropper. But I have seen a security video of someone dropping an open glass bottle and splashing acid in their face.
Safety goggles / glasses were essential in the days before testing sets were available, jewellers would mix their own acids in a flask fixed with a bung, and with fine capillary tubing coming out of the bung, and if the tubing was 'flicked' into the air it was possible to for a spot of acid to fly into someone's eye. My personal opinion is that eye protection is not necessary if you are using our plastic bottles. The same applies to full-face face protector (visor), £19.50 - my personal opinion is that you don't need one...but we do have them in stock should you wish to give us your money.
All this said, some of the big chains of stores use safety goggles / glasses, we do stock them, we do sell many dozens of them.
When you read, in the official COSHH safety data sheets, that protective clothing and a respirator should be worn, they are referring to an accident caused by a road tanker spilling its load of acid, not to handling a teaspoon-full. The precautions you take must be relative to the risk. Here in the laboratory we have some respirators with special anti-acid filters (a dust mask will not work!) which cost us £150.00 each. We have never worn them, they are just in case we have a major accident involving several litres of acid. We do not sell respirators, you will never need one when testing gold, not even if you spill the entire bottle of acid.
PRECAUTIONS. A standard warning is, "Keep the chemicals
away from combustible materials".
