    Hi everyone,

    I'm interested in preparing my own brine solution for quenching small carbon steel tools and steel clock components.

    Tubal Cain recommends using "vacuum-dried salt" as used by farmers to make butter, and also indicates a ratio of 80 - 100 g per liter of water (Workshop Practice Series 1 - Hardening, Tempering and Heat Treatment).

    Have any members tried this type of salt and ratio to prepare their own brine solution?
    If not, do any members have a recommendation on the best type of salt to use, and also a good weight ratio solution, ideally grams to liters?

    I can find what appears to be fairly coarse and unmodified sea salt sold in1 kilo bags, but I'm not sure if this contains any additives such as an anti-caking agent (The sea salt is imported and sold in a local bulk-purchase Asian supermarket and doesn't provide any other information than "Marine salt").

    Would an anti-caking agent have a detrimental effect on the solution, and if so, does anyone know what type and where the appropriate type of salt could be purchased? (I live in Europe, but if I know the type of salt I can try and source it locally. If you have a specific brand name for the salt that would help also).

    Hope you can help!
