jrengel21 Posted December 18, 2023 Share Posted December 18, 2023 Kids & I found corals fairly well preserved in the red clay/dirt & I soaked I water & small amount of vinegar. After cleaning with toothbrushes -They came out sparkly-like a crystalline cover. These are a couple smaller sections. Red clay is difficult to remove. Tips on removing clay without removing the sparkle? Are these worth anything or bother donating to museum. Thank you 2 Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 18, 2023 Share Posted December 18, 2023 Welcome to the Forum. You have a nice example of the extremely common coral Acrocyathus sp. This is a type of Colonial rugose coral, formerly called Hexagonaria. Lithostrotionella sp. We do not valuate fossils on the Forum, but this is extremely common, so it is of no monetary or scientific value. It is of course, very cool, and worthy of a place on a shelf or in a garden. The sparkle could be either calcite or druzy quartz. 2 1 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

I blame it on getting old and forgetful. 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Coco Posted December 18, 2023 Share Posted December 18, 2023 To remove clay from quartz or calcite, we have two main solutions: either put them in an ultrasonic tank (if the fossils do not have a crack) when they are dry, which will break the clay; or soak them once dry in a mixture of water + hydrogen peroxide, which will have the same result. You can repeat the operation if the result is not satisfactory, but in any case the fossil must be dry.
