Trinitydraco posted a topic in Questions & AnswersOkay so I have some questions on what you can and can't do with your typical trilobite in shale fossils. To help direct the discussion, I am interested in setting a small trilobite in silver as a gift. I make silver jewelry both using PMC (Precious Metal Clay) and traditional cutting and soldering. So, first question: Can you use high percentage (70% or higher) rubbing alcohol to clean all the dust and debris before sealing a trilobite? If not, what should I use? (I know you shouldn't use water) Question 2: What sealants can/should you use on a trilobite? I am looking for something that will be both waterproof and help prevent chipping. Question 3: Does anyone have any experience exposing them to high heat? It is common in jewelry making for heat to be involved, from both direct flame and indirect radiant heat. Is there any kind of precautions I should take and if so, what? What type of heat did you expose them to and what was the result? Different minerals act differently so remember we are talking about soft-medium shale. Question 4: Do you have any other advice or precautions you can give me regarding the use of fossil trilobites in/from shale matrix regarding their use in mixed media projects? The information I gather on this will help dictate my methods and help me create a plan for my project. There are many different ways I can do this and want to get a better idea of my options. Thanks. Picture is not of the exact trilobite to be used. It's just a reference for the kind of material/fossil I will be using.
-Andy- posted a topic in Questions & AnswersAs above. I am used to my fossils looking a tad darker or shiny when I apply a sealant to them. I use matte artist varnish. To me it's simply the trade-off of preserving them longer. I was rather surprised when I applied the same sealant to my Lebanon squid, and the tentacles darkened a lot. This is a unique situation as the tentacles were almost invisible originally, but now they are obvious (not so much that they stand out against the rest of the fossil though). I am not a fan of painting over Lebanese fossils to enhance their looks, so turning my squid tentacle from almost invisible to highly visible made me feel somewhat guilty.
I have a question. Does anyone have any knowledge of anyone attempting to use color enhancing sealers for stone and tile to bring out the colors on a fossil? I did tile installation for about seven years and we used it to bring out the colors in travertines and such. It gave the tiles a "wet" appearance, without the shine. I know it wouldn't take the place of a consolidating sealant like Vinac or Paraloid, but it might make the fossil stand out against a matrix, if the colors of both are similar. Just a question I've had, bouncing around my skull for awhile...
