In all cases, if the vat smells slightly of lime, it is a proof that it has enough; if it smells very strongly of lime, give 1 1/2 lb. of potash, and 2 lb. madder; then, if it smells of lime instead of woad, cool by taking off the covering, and a considerable quantity of the lime will evaporate: heat up again, and put in 30 or 35 lb. of woad; when hot, rake well up; look at the vat in 6 or 8 hours, if the upper part of the liquor looks yellow, rake up, and if it does not darken, use 2 quarts of lime; when you rake up, stir the bottom at all times, except when heating up; 3 hours is long enough for a woad vat to settle. In dyeing cotton or silk on this vat, it is safest to work it cold, or at most lukewarm.
