Buffered ragboard
Buffered ragboard is made of 100% cotton fibres and has the same high quality level as the normal museumboard. Also the ragboard has the addition of a very special sort of calcium carbonate to the cellulose results in an aid-free buffered ragboard with an alkaline reserve. Because of its composition this material is very aging-resistant.
The colours are natural, off-white and creme in several weights.
Non-buffered ragboard
Is also made of 100% cotton fibres, is specially made to storage or frame old black and white photo’s which can not endure an alkaline environment, because a buffering with calcium carbonate (CaCO3) gives a reaction with the silver oxides of black and white photo’s, that’s the reason why it’s unbuffered.
The colour is natural and it's available in several weights.
All our materials have to meet the highest quality-standards. Independant institutes will check our materials regularly.
