Description

second decoction to such / K ra and bath module.

The second broth is also boiled for 30 minutes.

After the second decoction, the samples are washed in a shade of 1 dmcplirorio aaio water (40–50 ° C) and their tissue is checked for complete decoction. Boiled down ;;; A complete, low-quality pbcrokarmino.xx joele wash gives a bright yellow coloration.

If the sample is proven, and the broth is boiled, 15 silk of the oak silkworm is boiled and washed, placed in an open bundle and dried in a cabinet and cabinet at a temperature of 105-110 ° C to a different weight.

If the sample does not show the fullness of the boiling, boil it in addition for 30 missions in the same composition of the solution and bath module, but then wash and dry to a different weight.

Uvar in the unit. X and humidity are calculated according to GOST 5618-58.

The predlozheniy1 method will shorten the time of determining uvara, it saves aids for uatar, electric power and labor.
