Betty McLaren was taught to slip cast by Reg Preston after moving with her husband Gus McLaren to Warrandyte in the early 1950s. Gus and Preston had started designing and making whimsical earthenware animals and domestic ware under the name Regus and Betty joined the team. The couple lived with Preston for a time, then set up their own Yarraridge Pottery in Bradleys Lane. Over time, Betty took over operation of the slip casting and decorating process, as well as working on her own hand-painted pieces, supplying the Potters Cottage and other galleries in Victoria. In the early 1980s, Betty moved to Merimbula, NSW, leaving her daughter Kirsty to run the pottery at Warrandyte. After Kirsty left for London in the mid-1980s, Betty moved production to Merimbula where she is still producing slip cast animals to Gus's original 1950s and 1960s designs under the name McLaren Pottery. Betty's works are signed 'B Mclaren' or 'Betty McLaren'. McLaren Pottery works are signed 'MCL' or 'McLaren'.
