Sparex is an easy to use, long lasting solution for removing fire scale from gold, silver, and copper, after soldering. Sparex is a non-flammable granular compound, and mixes with water. Mix about 1 teaspoon of Sparex per 1 cup of water, preferably in a crock pot or our hot pot. Heat to about 180* and it's ready to work. Use copper tongs to remove items from the pot.

Fire scale is a hard to remove surface coating that occurs when metal is heated from soldering. Sparex removes fire scale, without damaging the item, saving you valuable time spent polishing!
