Minnesota Nice Posted December 31, 2016 Share Posted December 31, 2016 My first shot at prepping ANYTHING! I will describe by process with the hope of some constructive criticism. PIX 1: I used only dental picks for this Oreodont partial jaw as the matrix is soft. I also found that a Qtip with water, softened some of the tougher spots. PIX 2: I used a soft bristle brush to apply a dilute acetic acid which served well to remove the last of the residual matrix. PIX 3: I neutralized the acid with a soak in Sodium Bicarbonate PIX 4: Into the oven at 200 F for one hour to drive off all moisture. PIX 5: Into a 5% solution of Paraloid. I used Pyrex brand with a snap lid and seal that does not react with the Acetone nor does the lid seem to get gummed up with the Paraloid. The piece was still warm when I put it in the Paraloid solution and it bubbled vigorously for several minutes as the solution soaked in. All told the bubbles lasted for 1 hour. PIX 6: Cool shot of air escaping the piece. PIX 7: To slow down the evaporation of the Acetone, I sealed the piece in a ziplock and placed in at 25 F (note the snow!!! this is Minnesota) I could see the Acetone condensate on the bag. After 1 hour I opened the bag and let it dry completely. PIX 8: Finished and on the way to my 8 year old grandson in Florida!

jpc Posted December 31, 2016 Share Posted December 31, 2016 NIce. My one concern s that when you bake it, some trapped water could cause it to explode. That would be bad. I can't tell from the photo, but does the final product look shiny? Link to comment Share on other sites More sharing options...

The slow evaporating is supposed to help with the shine but I think I will give it an acetone buff. I will post an updated shot Frango Ut Patefaciam...I Break in Order to Reveal Link to comment Share on other sites More sharing options...
Ptychodus04 Posted January 3, 2017 Share Posted January 3, 2017 I prefer to allow the acetone on the specimen to evaporate quickly then apply acetone to the surface to reduce the shine.
