Butvar B-76 for Autunite or Fossil preservation – Ten Grams

Reversible-Can be removed

Butvar B-76 is a type of acrylic resin that is commonly used in the preservation and conservation of cultural heritage objects. It can be used to protect autunite, which is a type of mineral that is known to deteriorate over time due to exposure to light, heat, and dry air. B-76 will provide structural support but may not prevent dehydration.

Here are the suggested steps for using Butvar B-76 to stabilize autunite:

  1. Clean the surface of the autunite using a soft brush and water to remove any dust or dirt.
  2. Dry the Specimen for 24 hours by storing it a safe room temprature enviornment. (Wet autunite will not stabilize properly and a white residue will result.)
  3. Document the weight of the specimen to be stabilized.
  4. Dissolve Butvar B-76 in a suitable solvent, such as acetone or 100% ethanol, to create a solution with a concentration of aroundĀ  5%. This can be done by adding 5 grams of B-76 to 95 grams of solvent and stirring until it is fully dissolved.
  5. Apply the Butvar B-76 solution to the surface of the autunite. It can be done using a dropper, or the specimen can be dipped into the solution.
  6. Immediately after the B-76 application, use light puffs of canned air to blow away any excess solution and prevent pooling.
  7. Allow the Butvar B-76 to dry completely, which can take several hours depending on the environment.
  8. Any remaining white or shiny residualĀ B-76 can be removed with a quick rinse of solvent followed by air.
