Abstract

MAKER:    Design  and  Create  with  Natural  Dyes      Dyeing  with  natural  dyes  is  a  combination  of  science  and  art.    The  science  dictates  that  a  permanent  bond  requires  a  metal  ion  –  a  mordant  –  to  bridge  between  the  fabric  and  the  dye.    The  art  allows  a  multitude  of  colors.    By  varying  the  combination  of  dye  and  mordant,  and  the  purity  and  concentration  of  each,  a  nearly  infinite  number  of  shades  can  be  obtained.        A  course  open  to  all  students  explored  the  history  and  technology  of  dyes  and  the  dyeing  process.    Simple  exercises  allowed  students  to  extract  dyes,  discover  the  colors  obtained  by  combining  different  mordants  and  dyes,  and  note  how  fabric  type  contributed  to  the  shade.    Other  laboratory  exercises  introduced  resist  dyeing  techniques  from  Asia  and  Africa.    For  the  final  course  project,  each  student  designed  and  created  his  or  her  own  silk  scarf  using  the  techniques  learned  in  class.    The  scarves  created  by  the  students  were  outstanding  and  exhibited  their  willingness  to  try  a  new  design.    For  example,  Zach  wanted  to  create  the  illusion  of  a  branch  of  bamboo  growing  along  the  length  of  his  scarf.    He  planned  three  different  colors:    a  brown  foundation  representing  the  dirt,  followed  by  yellow  changing  gradually  to  green  and  finally  blue.      He  used  Shibori  techniques  to  design  the  bamboo  branch,  and  used  scraps  of  silk  to  determine  the  combination  of  mordant  and  dye  to  yield  the  shades  he  desired.        The  students  kept  the  scarves  they  dyed,  so  photos  of  them  will  be  displayed.    However,  the  author  dyed  silk  squares  in  various  combinations  of  mordant  and  dye,  and  and  crafted  a  quilt  from  the  squares.    The  quilt  demonstrates  the  range  of  colors  available  with  four  natural  dyes  and  five  mordants,  as  well  as  some  artistic  flair.
