Gathering and Grading Oak Galls: Blue Galls Before the Insect Escapes (Tomlinson, 1854)
How the best ink and dye galls were harvested: the hard round galls of the dyer's oak picked at full size and weight, before the gall wasp bores out, then sorted into heavy blue galls and light, holed white galls.

Watch the galls
During the season walk the oaks often and watch the galls grow on the shoots and branches. They are hard, round and knobbed, from pea to nutmeg size.

Gather in time
Gather in time
Pick them as soon as they reach full size and weight, before the insect inside matures and bores out through the shell; any delay spoils them.

Sort them
Sort them
Sort the heavy, bluish 'blue galls' with no hole (the best, for ink and black dye) from the larger, lighter, brownish or yellowish 'white galls' with a small round hole (inferior). Check doubtful ones by weight; a whitish gall dyed blue shows too deep a colour, is light, and has the hole.
