Re: Re Block storage

From:Amos Brooks

    Coating the block will not make any difference to the environmental
control factor. If the area gets too hot, the blocks will soften and
eventually melt together with or with out the coating. Oxidation, or similar
decomposition may be prevented but so will facing off the affected area
before cutting.
    Small specimens can't be faced off like this, but since it is difficult
to see the specimen when removing the coating, so facing through the
specimen still presents a problem.
