Safety with our product is important. 

The small bag with the Silver nitrate crystals are a VERY strong oxidiser.  It can stain anything it touches including your skin and eyes.  ALWAYS USE PPE such as safety glasses, nitrile gloves and a mask when mixing and using our kits.  Also please use on an expendable surface - as the tiniest Silver Nitrate crystal can leave a permanent dark brown stain.  


Here are links to the MSDS For these chemicals. - Silver Nitrate - Tiny Bags of Crystals - Black or Smokey clored bags in our kits. - Sodium Thiosulfate - Larger Bags of Crystals.  Comes in clear bag in all kits.
