PACKING

VINEGAR

GENERATORS.

The

next

step

in

the

process

consists

in

acetifying

the

chips,

&c.

This

consists

in

passing

pure

vinegar

through

the

generator,

until

every

chip

and

shaving

is

perfectly

saturated

with

vinegar.

This

object

will

be

fully

obtained

by

pouring

and

repouring

the

vine*

gar

as

fast

as

it

runs

through,

some

eight

or

ten

times.

It

is

highly

essential

that

the

vinegar

used

in

ace-

tifying

the

chips,

should

be

pure,

or

free,

at

least,

from

the

mineral

acids.

The

most

common

adultera-

tion

of

sulphuric

acid

can

be

detected

by

saturating

strips

of

glazed

writing

paper

with

the

vinegar.

If

when

the

paper

becomes

dry

and

is

of

a

purplish

color,

it

will

denote

sulphuric

acid.

For

the

detec-

tion

of

the

usual

adulterations

of

vinegar,

look

under

the

proper

head.

The

last

step

in

the

process

consists

in

preparing

the

liquid

that

is

to

be

converted

into

vinegar.

To

forty

gallons

of

rain

water,

add

twelve

gallons

of

proof

whiskey,

and

one

and

a

half

pints

of

honey.

This

mixture

is

allowed

to

fall

from

a

cock

in

the

barrel

that

contains

it

on

to

the

head

of

the

generator,

and

by

the

aid

of

the

holes

in

the

head,

this

liquid

becomes

uniformly

divided

over

and

throughout

the

chips.

The

particles

of

fluid

becoming

so

minutely

divided,

is

the

cause

of

the

rapid

acetification.
