Explosive stuff!
August we focus on Chemicals.
Safety first:
Always wear the correct protective gear when using chemicals- Leather apron, thick gloves, goggles. It is also important to have the right ventilation in your workspace.

TIps for your workshop:
  • Instead of using a dangerous acid to quench your metal into try out our pickle salt
     or Alum
  • Ultrasonic cleaner - mersolve- an excellent and affordable concentrate for very dirty jewellery.
  • Do you know how to prep your crucible before using it the first time? Click here to find out more.
  • When oxidising metal remember it will go darker if the oxidising solution is heated or the metal item is heated.
Neutralize:  
Acids typically have a sour taste & a pH less than 7. To neutralize them, use a weak base. There are two types of acids: mineral (inorganic) acids such as sulfuric, hydrochloric or nitric, and carboxylic (organic) acids such as formic or acetic.
Many different products aid in the neutralization of acids and bases. They can be as simple as a bag of citric acid or sodium bicarbonate, or as complex as a solidifier & neutralizer combined.
Take proper precautions as recommended by the neutralizer’s manufacturer.

Etching:
We sell a chemical for etching on silver.,brass or copper that is less hazardous that nitric. Why not try them out?
Solder flux:
Should always be stored out of sunlight- Non toxic. Use flux to provide "flow" to the area you are soldering. Can be used on gold, silver and platinum. Use with a natural hair brush.
Borax:
Used to prepare crucibles, a sprinkle of borax while melting gold & silver scraps helps clean up dirty metal.
