Abstract
We report on submillimetre observations of three high redshift (z>6) quasars, made using the SCUBA camera on the JCMT. Only one of the sample was detected at 850um-- SDSS J1148+5251 (z=6.43). It was also detected (>3 sigma significance) at 450um, one of the few z>4 quasars for which this is the case. In combination with existing millimetric data, the submm detections allow us to place limits on the temperature of the submm-emitting dust, hence on the mass of dust to be synthesized under the time constraint imposed by the quasar's redshift.
