Response to Tech Pan Developing Question for Martin Tai

> 100 lbs bags

The smallest size sold by Kodak is one-pound bottles; I found it as KOSSLB 1463538 $8.50 listed under Bulk Chemicals, and it's shown as special-order. They sure didn't make it easy to find.

A quick look at Photographers Formulary (www.photoformulary.com) turns up this: 0-1340 Sodium Sulfite 1 lb 4.95.

Also at Calumet (www.calumetphoto.com) Kodak sodium sulfite item # KP02074 $7.50.

Sodium sulfite is sodium sulfite, brand doesn't matter. It can also be obtained from some pool-supply dealers, but there's not much point in buying a huge quantity even if it's cheap because it's hygroscopic.

Also note that sodium sulf_ite_ is different than _ide_ or _bisulfite_.
