I told the owner of my lss about the chalk catseye inks and she wrote the company and asked for a statement to print and display by the inks so customers could decide for themselves if they whis to use them or not. The following is the reply she got:
Dear Linda,
Please publish the following:
COLORBOX Fluid CHALK inks are considered archival and safe for keepsake
projects. Although they technically test below "Neutral" on the pH
scale, they are within a range considered acceptable for Scrapbook
applications. The "Chalk" element contained in these inks is a Base
material (non-acidic) and serves to stabilize the inks once dried, much
as the various buffers and fillers used in modern papers are used to
neutralize acidic elements.
As with all stamping inks, make sure they are dry before enclosing them
in your project. If CHALK Inks are used on a coated or glossy paper,
you may want to buff them after drying with a clean tissue to remove any
chalky residue. COLORBOX Fluid CHALK Inks have been used extensively
for scrapbooking with great results and no reported adverse effects.They
are much more fade resistant and permanent than most standard dye inks
normally used for stamping.
