 It could be epoxy and if so, prolonged insertion in boiling water may work. No 
 Do NOT use the XYL's best saucepans - trouble is definitely guaranteed if you 
do! Even if it does work, the saucepan may well not be fit for culinary use

  Subject: [Amps] E-core transformer
  Some time back, some one on this list had a suggestion for 
  dis-assembling the E-core ferrite transformers typically found in 
  switching power supplies. I've had good results using them in low band 
  SSPA's and would like to use more in my latest project.
  I have a quantity of salvaged transformers that I want to re-use but am 
  having a lot of trouble taking them apart so that I can rewind. I've 
  tried heating with a heat gun, but the ferrite falls apart before the 
  varnish gets soft. Any suggestions?
