First safety pickle I've bought as new to making metal jewellery. Works well quickly.
Safety pickling compound is used to remove oxidation on metals; like the black surface you might see on your copper clay after firing, or on your sterling silver after soldering.
Add roughly 10g of safety pickling compound with 40ml of hot water (about 50°C) in a heatproof container, and stir until the crystals are dissolved. Then immerse your cooled metal piece in the pickling solution for around 5-10 minutes until the oxidation is gone, and remove with tweezers. It is a good idea to neutralise your metal clay after pickling, this can be done by first rinsing your piece, then putting it into a mix of hot water and bicarbonate of soda. Leave for a few minute and rinse.
This pickle can be used with non-ferrous metals like platinum, gold, silver, copper and brass. Pickle different metal types separately.
Avoid contact with your skin, eyes, and mouth.
Contains 270gm. Comes with detailed instructions.
Easy to use and fast to clean up the fire scale, great on bronze and copper
Good value safety pickle. Dissolves quickly. Does the job well. Large tub for the price, should last quite a while.
