Sir Ellis! Back on stage! What a positive surprise!
What more to say I would do offline.
Thanks for advice, always distinct and worth saving. Like Bev, I've saved a lot from you. May make a book of your letters and make money. Like Moon Man. He-he..
Facts: I'll check with Dr K Wack (not joking). Think we have adequate equipment, 15 m long washingmachine with closed doors and lots of ventilation. Hmmm...just wondering about the dead seagulls on the roof...(now joking).
Have a nice and calm and relaxed day, will tell Paul Klasek and the others.
Ingemar

Vigon A200 is an excellent saponifier, but, like all saponifiers,
requires caution in its use. It is very basic and is quite toxic. Unlike
most organic saponifiers, it does not use MEA, but it does have an
analogic amine, with more carbon. Operator protection is a must. It is
also a VOC. I can recommend its use, but only in suitable equipment and
with correct operator protection and training.
