[Histonet] Thanks Glycerin-Gelatine bubble-phenomen

From:"Barbara Bublava"

I want to thank all the people who responded to my question!

What finally did help was the treatment with a mixture of formalin and
sulfanilic acid.
No more bubbles - even after several days.

Thanks a lot
Barbara Bublava
