We dissolve the gum lumps in boiled but cooled (20C) water and when all
lumps are dissolved we strain it, check the Baume and then we add
formaldehyde. The gum we used was the best we have found during the years.
Bright lumps and when in solution still very transparent. This time we
wanted to try glyoxal but we did not get the chance....
The only difference this time was that "glyoxal was in the air". The gum
lumps were placed in a brown paper bag in another bag 5-7 meters away from
the sizing tray!

We have tried gum powder several times but the one we have used gives a
very brownish solution.
Thanks for your help
