Hi Lela. Friends of mine around here in Berkeley have often used a
10% solution of iron chloride to get effects in raku. You get that
by adding 10 grams of iron chloride to 100 milliliters of water. Be a
little careful and add the chloride to the water slowly... iron chloride
has the unusual characteristic of generating heat when it dissolves in
water, and although a 10% solution shouldn't really get hot, it's always
wise to mix it gradually. Also, iron chloride is corrosive, so you
should not only wear a respirator when you fume your raku pieces, it's
a good idea to wear one when you're handling and mixing it too.

Subject: ferric chloride mixing question
Hello all,
I plan to spray ferric chloride on a couple of pieces at our next guild
raku. Have checked the archives and learned one should wear protective
clothing and a good respirator, but could not find how to mix. I have the
gold-brown powdered stuff. Like a teaspoon per cup of water..a tablespoon?
Hot water, doesn`t matter?
Thanks from Lela

I use the liquid form of Ferric Chloride, I've not tried the powder. I mix
the liquid 3 tablespoons per quart of water. Cold water works fine for the
liquid.
As far as the amount of Ferric Chloride to use in your case, it all depends
on the final color you are trying to achieve.
The color of the Ferric Chloride I get in the container after mixing it with
water is a little darker than honey.
I guess you will just have to experiment to get the final color you desire,
Hope something in this helps.
Make sure you and any others near by are properly protected. It is a
dangerous product.

Hello Gary H, Gene A., Barbara,
Thank you for responding to the mixing question. I will do the 10%, taking
it slow and careful. Best wishes from
Lela, who is loving that the days are longer.
