There　is　a　method　of　bronzing　casts　of　plaster　of　Paris　analogous　to　that
  which　we　have　above　given　for　bronzing　wood；　but　it　is　not　in　much　repute。
  Such　figures　may　be　beautifully　varnished　by　means　of　Dr。　John's　varnish；
  receipt　No。178。　Casts　of　plaster　of　Paris　may　be　made　by　receipt　No。167。
  183。　SHELL…LAC　VARNISH
  Dissolve　in　an　iron　kettle；　one　part　of　pearl…ash　in　about　8　parts　of
  water；　add　one　part　of　shell…lac；　and　heat　the　whole　to　ebullition。　When
  the　lac　is　dissolved；　cool　the　solution；　and　impregnate　it　with　chlorine；
  till　the　lac　is　all　precipitated。　The　precipitate　is　white；　but　its　colour
  deepens　by　washing　and　consolidation；　dissolved　in　alcohol；　lac　bleached
  by　the　above　process　yields　a　varnish　which　is　as　free　from　colour　as　any
  copal　varnish。
  184。　CHLORINE　FOR　SHELL…LAC　VARNISH
  This　may　be　formed　by　mixing　intimately　eight　parts　of　common　salt；　and
  three　parts　of　the　black　oxide　of　manganese　in　powder；　put　this　mixture
  into　a　retort；　then　pour　four　parts　of　sulphuric　acid；　diluted　with　an
  equal　weight　of　water；　and　afterwards　allowed　to　cool　upon　the　salt　and
  manganese；　the　gas　will　then　be　immediately　liberated；　and　the　operation
  may　be　quickened　by　a　moderate　heat。　A　tube　leading　from　the　mouth　of　the
  retort　must　be　passed　into　the　resinous　solution；　where　the　gas　will　be
  absorbed；　and　the　lac　precipitated。
  185。　SHELL…LAC　VARNISHES　OF　VARIOUS　COLOURS
  These　may　be　made　by　using　ant　colour　in　fine　powder　with　the　varnish；　in
  the　following　manner：　rub　up　the　colour　with　a　little　alcohol　or　spirits
  of　turpentine　till　it　becomes　perfectly　smooth；　then　put　it　into　the　cup
  with　the　varnish。　Shell…lac　varnish　is　the　best　spirit　varnish　we　have；
  and　may　be　made　any　colour　by　the　above　process。
  186。　GOLD　OIL…COLOUR；　OR　SIZE
  The　English　method　of　preparing　the　colour　in　size；　which　serves　as　the
  ground　on　which　the　gold　is　laid；　is；　to　grind　together　some　red　oxide　of
  lead　with　the　thickest　drying　oil　that　can　be　procured；　the　older　the
  better。　To　make　it　work　freely；　it　is　mixed；　before　being　used；　with　a
  little　oil　of　turpentine；　till　it　is　brought　to　a　proper　consistence。　The
  above　four　receipts　are　used　in　japanning。
  187。　JAPANNING
  If　it　be　woodwork　you　are　about　to　japan；　it　must　be　prepared　with　size；
  and　some　coarse　material　mixed　with　it　to　fill　up　and　harden　the　grain　of
  the　wood；　（such　as　may　best　suit　the　colour　to　be　laid　on；）　which　must　be
  rubbed　smooth　with　glass　paper　when　dry。　In　cases　of　accident；　it　is
  seldom　necessary　to　resize　the　damaged　places；　unless　they　are
  considerable。
  188。　GRINDING　COLOURS　IN　JAPANNING
  Be　very　careful　in　japanning；　to　grind　your　colours　smooth　in　spirits　of
  turpentine；　then　add　a　small　quantity　of　turpentine　and　spirit　varnish；
  lay　it　carefully　on　with　a　camel　hair　brush；　and　varnish　it　with　brown　or
  white　varnish；　according　to　the　colour。
  189。　COLOURS　REQUIRED　IN　JAPANNING
  Flake　white；　red　lead；　vermillion；　lake；　Prussian　blue；　patent　yellow；
  orpiment；　orchres；　verditers；　vandyke　brown；　umber；　lamp…black；　and
  siennas　raw　and　burnt。　With　these　you　may　match　almost　any　colour　in
  general　use　in　japanning。　For　a　black　japan；　it　will　be　found　sufficient
  to　mix　a　little　gold…size　with　lamp…black；　this　will　bear　a　good　gloss；
  without　requiring　to　be　varnished　afterwards。
  190。　TO　PREPARE　A　FINE　TORTOISE…SHELL　JAPAN
  Take　1　gallon　of　good　linseed　oil；　and　1/2　lb。　of　umber；　boil　them
  together　till　the　oil　becomes　very　brown　and　thick；　then　strain　it　through
  a　coarse　cloth；　and　set　it　again　to　boil；　in　which　state　it　must　be
  continued　till　it　acquires　a　consistence　resembling　that　of　pitch；　it　will
  then　be　fit　for　use。
  191。　DIRECTIONS　FOR　USING　TORTOISE…SHELL　JAPAN
  Having　thus　prepared　the　varnish　or　japan；　clean　well　the　substance　which
  is　to　be　japanned；　then　lay　vermillion；　tempered　with　shell…lac　varnish；
  or　with　drying　oil；　very　thinly　diluted　with　oil　of　turpentine；　on　the
  places　intended　to　imitate　the　more　transparent　parts　of　the
  tortoise…shell；　when　the　vermillion　is　dry；　brush　the　whole　over　with
  black　varnish；　tempered　to　a　due　consistence　with　the　oil　of　turpentine。
  When　set　and　firm；　put　the　work　into　a　stove；　where　it　may　undergo　a
  very　strong　heat；　which　must　be　continued　a　considerable　time；　if　even
  three　weeks　or　a　month　it　will　be　the　better。　This　tortoise…shell　ground
  it　not　less　valuable　for　its　great　hardness；　and　enduring　to　be　made
  hotter　than　boiling　water　without　damage；　than　for　the　superior　beauty　and
  brilliancy　of　its　appearance。
  192。　TO　MAKE　CLOTH；　SILK　&c。；　WATER…PROOF
  Mix　equal　quantities　of　alum　and　acetate　of　lead；　and　dissolve　the　mixture
  in　1　1/2　gallons　of　boiling　water。　When　the　solution　has　cooled；remove　the
  supernatent　liquid　from　the　sediment；　which　consists　of　sulphate　of　lead；
  and　is　ready　for　use。　Any　article　of　dress；　when　well　saturated　in　this
  liquid；　and　allowed　to　dry　slowly；　bears　the　action　of　boiling　water；　and
  does　not　permit　it　to　pass　through；　although　steam　and　air　penetrate　if
  freely。
  193。　CROCKERY　CEMENT
  Dissolve　1　oz。　of　common　salt　in　1　quart　of　water；　bring　to　a　boil；　and
  put　in　1　1/4　lbs。　gum　shell…lac；　when　it　shall　have　dissolved；　pour　into
  cold　water；　and　work　like　wax；　make　into　small　sticks。　This　will　make
  crockery　as　firm　as　a　rock。　Directions：　…　Warm　the　stick；　apply　it　to　the
  broken　edges；　then　heat　the　edges；　place　them　together　and　hold　for　a
  minute；　and　they　are　firm。
  194。　A　CEMENT　FOR　CHINA；　GLASS…WARE；　&c。
  Take　a　thick　mucilage　of　gum　arabic；　and　stir　into　it　plaster　of　Paris　to
  form　a　thick　paste；　apply　to　the　edges　with　a　brush；　and　press　firmly
  together　and　confine　them　two　or　three　days；　and　you　will　be　astonished　at
  their　firmness。
  195。　ANGLER'S　SECRET
  The　juice　of　loveage　or　smellage　mixed　with　any　kind　of　bait；　or　a　few
  drops　of　the　oil　of　rhodium；　India　cockle；　also；　is　sometimes　mixed　with
  flour　dough；　and　sprinkled　on　the　surface　of　still　water。　This　intoxicates
  the　fish；　and　makes　him　turn　up　on　the　top　of　the　water；　when　he　is　taken
  and　put　in　a　tub　of　fresh　water　until　he　revives；　when　all　is　right；　he
  may　be　eaten　without　fear；　but　this　will　destroy　many　fish。
  196。　MORELLA　WINE

  of　water；　and　4　lbs。　of　coarse　brown　sugar；　let　them　ferment；　and　skim
  until　worked　clear；　then　draw　off；　avoiding　the　sediment　at　the　bottom；
  bung　up；　or　bottle；　which　is　best　for　all　wines；　letting　the　bottles　lie
  always　on　the　side；　either　for　wines　or　beers。

  best　on　which　to　apply　it。　As　soon　as　dry；　wash　out　well　with　soap。　Keep
  it　from　shirt　bosoms　and　face；　especially　No。1；　as　it　will　make　the　face
  sore　as　well　as　colour　it。　If　you　do　get　it　on　the　skin；　cyanide　（cyanuret
  is　the　same）　of　potassium；　1　drachm；　to　2　ozs。　of　water；　will　take　it　off。
  This　last　is　poison；　however；　and　should　not　touch　sore　places；　nor　be
  left　where　children　may　get　at　it。
  198。　TALLOW　CANDLES　IN　IMITATION　OF　WAX
  Purify　melted　mutton　tallow　by　throwing　in　powdered　quicklime；　then　add　2

  wish　a　scarlet　tint；　boil　an　ounce　of　saffron　in　a　quart　of　water；　and
  pass　over　the　work　before　you　stain　it。　The　article　must　be　very　clean；
  and　of　firwood；　or　the　best　sycamore。　When　varnished　over　this　stain　it　is
  most　elegant。
