  Solution growth of single crystals from high temperature solutions often
involves the separation of residual solution from the grown crystals. For many
growths of intermetallic compounds, this separation has historically been
achieved with the use of plugs of silica wool. Whereas this is generally
efficient in a mechanical sense, it leads to a significant contamination of the
decanted liquid with silica fibers. In this paper we present a simple design
for frit-disc alumina crucible sets that has made their use in the growth
single crystals from high temperature solutions both simple and affordable. An
alumina frit-disc allows for the clean separation of the residual liquid from
the solid phase. This allows for the reuse of the decanted liquid, either for
further growth of the same phase, or for subsequent growth of other, related
phases. In this paper we provide examples of the growth of isotopically
substituted TbCd$_{6}$ and icosahedral i-$R$Cd quasicrystals, as well as the
separation of (i) the closely related Bi$_{2}$Rh$_{3}$S$_{2}$ and
Bi$_{2}$Rh$_{3.5}$S$_{2}$ phases and (ii) PrZn$_{11}$ and Pr$_{2}$Zn$_{17}$.
