Paraloid B-72 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.

Here are the suggested steps for using Paraloid B-72 to stabilize autunite:

  1. Clean the surface of the autunite using a soft brush or cloth to remove any dust or dirt.
  2. Document the weight of the specimen to be stabilized.
  3. Dissolve Paraloid B-72 in a suitable solvent, such as acetone or 100% ethanol, to create a solution with a concentration of around 10% This can be done by adding 10 grams of B-72 to r to 90 grams of solvent and stirring until it is fully dissolved.
  4. Apply the Paraloid B-72 solution to the surface of the autunite using a brush or dropper. Make sure to apply a thin, even layer and avoid creating any drips or pooling of the solution.
  5. Allow the Paraloid B-72 to dry completely, which can take several hours depending on the temperature and humidity of the environment. It will end up weighing up to a few hundred milligrams heavier than the pre-treatment weight.
  6. Repeat steps 3 and 4 as necessary to achieve the desired level of protection.
  7. Any remaining white or shiny residual B-72 can be removed with a quick rinse of solvent.
  8. Continue to monitor the weight of the specimen for dehydration as further treatments may be necessary.

It’s important to note that the use of Paraloid B-72 should only be undertaken by professionals with proper training and experience in the conservation and preservation of cultural heritage objects. Additionally, the specific method of using Paraloid B-72 to preserve autunite may vary depending on the condition of the object and the desired level of protection.
