To Wash Wool

In a bath containing 10 gallons of warm water add 4 fluid ounces of
ammonia fort, .880, 1 lb. soda, and 2 oz. soft soap, (potash soap).
Stir well until all is dissolved. Dip the wool in and leave for 2
minutes, then squeeze gently and wash in warm water until quite clear.

Or to 10 gallons of water add 6 oz. ammonia and 3 oz. soft soap. The
water should never be above 140 deg.F. and all the washing water should
be of about the same temperature.

Fleece may be washed in the same way, but great care should be taken
not to felt the wool--the less squeezing the better.

There are four principal methods of dyeing wool.

1st.--The wool is boiled first with the mordant and then in a fresh
bath with the dye.

2nd.--The wool is boiled first with the dye, and when it has absorbed
as much of the colour as possible the mordant is added to the same
bath, thus fixing the colour.

A separate bath can be used for each of these processes, in which case
each bath can be replenished and used again for a fresh lot of wool.

3rd.--The wool is boiled with the mordant and dye in the same bath
together. The colour, as a rule, is not so fast and good as with a
separate bath, though with some dyes a brighter colour is obtained.

4th.--The wool is mordanted, then dyed, then mordanted again. This
method is adopted to ensure an extremely fast colour. The mordant
should be used rather sparingly.
