Dear Martin Kastner,=20

I am uncertain about having the knowledge to answer your questions but =
first I would like to give you support by telling you I admire those who =
choose to be Designers.During my life I have enjoyed the company and =
friendship of many. Ted Renolds, who was Graphic Designer for Faber and =
Faber and Brenda Bentall who designed Carpets for a Scottish Company to =
name but two. Be proud of your skill and do not be put down by those who =
would seek to despise your calling.

Now to your question. Graphite will act as an oxygen scavenger but =
Charcoal might work better. Finely divided Magnesium metal powder will =
also react as temperature rises and will not create either Carbon =
dioxide or Carbon monoxide, which, if they escaped from a Sager, have =
the potential to damage the elements of an electric kiln. Only trials =
would show which would be the better option.

Best regards,

Ivor Lewis.

Ivor,
Thank you for your response. I appreciate your encouragement.
Can you elaborate on the Magnesium powder method? To my knowledge Magnesium
is a rather dangerous material as it is sensitive to both heat and moisture
and can become explosive.
Thanks,
