A frit manufacturer that used to publish chemistry

I was impressed with this frit company, Reimbold & Strick. Their frit data was educational, by studying the chemistry of their matte frits, for example, you could see the various mechanisms that produce the effect. But, it is no longer available. However, with a little determination you could likely find the pages at the internet archive (see link below).
