Lawrence has been making copies of Roman mosaics since starting his training in Ravenna, Italy in 2002. His first instructional video on using the hammer and hardie was uploaded to Youtube in 2009 and since then he has added many more.
His use of these tools has been for cutting large volumes of marble tesserae, 5 - 6 hours of cutting was not unusual. On one occasion all 24,000 tesserae for one particular mosiac were hand cut from tiles ranging in size from 10cm to 30cm square and all 1cm thick.
Many years of practice and then teaching these skills has allowed Lawrence to understand all the mistakes that can be made and how to get people over them.
