We’ve completed the pilot phase for our study! In this phase we looked at all the different methods of testing stone bioreceptivity in the literature.

We then selected one to take forwards for looking at different stone types and with a few tweaks to the methodology we have a protocol which will work for most types of stone used in the heritage field. Next step is to start looking at adapting this methodology to give us a lab based test for biocides which will show whether they change the bioreceptivity of the surfaces, oh and get the pilot phase written up and published!
