block trimming indicator

From:Clarke Ian

Hi All,
I have been asked if anyone knows of a technique which would show how far a
wax block has been trimmed before the cutting stage.Like most people we
utilise knowledge and expertise to determine if the block has been trimmed
in far enough.However,we have been asked to try and quantify the procedure
for trainee's so that they are unable to trim too far into a block as there
would be a visual indicator present.
Someone suggested if there was a coloured marker present in each block of a
soft material/wax which would indicate levels within the block and not
effect the cutting properties of the block , one could embed it along with
the tissue.
I am looking for suggestions and hope someone in histoland might have come
across such a method.
