Things that I keep looking up

So, I keep looking up very mundane things over and over, so, I'm going to write them down:

Vinegar is a acid.
Ammonia is a base.
Baking soda is also a base.

For four ounces of wool this is the formula if I plan on using an alum/cream of tartar mordant:

4 oz of wool, mordanted with 2 T alum and 1.5 t of Cream of Tartar, simmered for about 35-40 minutes

...And the new kitten has escaped and fell into the wool washing tubs...
