Another minor quibble some have is that microchamber is a >corrugated board (which sometimes provides a good hiding place for >insects to lay their eggs). I appreciate the kind comments from George Leake and Craig Jensen, however I would like to clear up a couple of misconceptions. MicroChamber paper is not a paper containing "activated charcoal". MicroChamber paper contains a combination of alkaline buffers and molecular sieves, or a combination of alkaline buffers, molecular sieves and activated carbon. Both the molecular sieves and the activated carbon we use were developed specifically for MicroChamber products. While MicroChamber products are available in corrugated boards, they are also available in .007" thick envelope/wrapping paper, .012" file and map/print folder paper, .043" and .065" thick solid fiber boxboards. We hope to have a very thin, translucent MicroChamber interleaving paper available soon. Also, MicroChamber technology museum mat and mount boards, rag and alpha cellulose, are available under the name "Artcare" from Nielsen & Bainbridge, (201) 368 9191. Finally, MicroChamber products surround the artifact and deal both with by-products of deterioration produced as a collection ages and with external pollutants, whether from indoor or outdoor sources. HVAC systems will not do this, and are not effective with such common pollutants as NOx.
