Debbie,

   I too have had this happen, With GI biopsies take them backwards through
the process. If you remove the parffin in the clearing agent and the
largest piece appears clear then reinfiltrate with parffin. If the largest
piece does not appear to clear then go back to 100% ethanol 2  changes
20-30 minutes room temp. then the clearing agent 20-30 minutes. Check the
tissue visually to make sure that it is clear before re-infiltrating with
paraffin. This works!
