Health and Safety

There are no acute or known chronic health hazards associated with the anticipated use of this product (most chemicals are not fully tested for chronic toxicity). Always protect yourself against potentially unknown chronic hazards of this and other chemical products by keeping them out of your body. Do this by avoiding ingestion, excessive skin contact, and inhalation of spraying mists, sanding dust, and vapors from heating. Conforms to ASTM D-4236.

Note: Some separation of pigment and medium may occur in Rublev Colours Watercolors and is a natural process when no stabilizers are added to paint to prevent this from occurring.
