Hi,
(Article extracted from the Rio Grande Philatelic Bulletin, Year V, no. 1, March 1999, p. 17-18) :
Inside the Brazilian stamp collecting, stamps called "marbled" are increasingly gaining new followers. Many philatelists are trying to complete your collection of marbled, but among the 148 known there are some very rare and scarce. Another major difficulty is that no one knows for sure what is the existing number of marbled many cataloged. It is said, in some cases, a sheet, but it is not known if the entire sheet was marbled or only part of it. So the doubts among collectors and even among traders are very large and this does not have a precise idea of the rarity and the great uncertainty of the real value of each stamp.
To define what is marbled paper, we reproduce part of an article published in the Newsletter Fontoura Wieth August 1990 and written by the late journalist philatelic JL de Barros Pimentel: "It is not different paper watermark or curious, but only defect papermaking. Visiting we did recently at Klabin Industries in Capital for special deference director of the firm, Mr. J. Klabin (veteran numismatist), and accompanied by one of the engineers of the firm, we were able to verify "in loco" the making of this paper, known as plastered or coated. still paper reel, humid, receives special machine in the bath milky substance consisting of kaolin and casein (fastener). After the bath, the sheet of paper undergoes the treatment of a variety of brushes, which acting in a constant back and forth that substance spread evenly. When, by chance, these brushes stop working a few moments, the substance is not spread out properly and paper then with that aspect congnominaram the "marbled".
This piece of coil with marbled paper has no fixed place, it may be the beginning, middle or end of the coil and the coil as is delivered to the Mint by the manufacturer, it is not possible to check it unfolds where the paper was flawed . This paper is ranked in the factory as "scrap". Meets the Mint, after the issuance of any stamp printed in that paper, separate the leaves that have coincided in part defective, incinerate them and not put them on sale with the rest of the issue, and then appear on the market for very high prices . "
Actually it is very difficult for the postal workers can identify one or more sheets that present rag inside a package of sheets. Only the watchful eye of a philatelist would be able to separate the sheets to present the characteristic of "marble shafts" that identifies this role.
Also, the "defect" may appear in part or in whole leaf which hinders further identification.
The first "marbled" appeared in 1956 (RHM 384Y) and the last in 1972 (RHM 769/72Y).
