I'm hoping someone on clayart can advise about protecting a ceramic
sculpture, glazed with a low-fire matt lithium glaze, from excessive algal
growth and such? I'm presently working on a 3'6" Cycladic Goddess, (see
website www.amamenec.co.uk Goddess link for photos) that I'm hoping will
sell well to those who would like a lovely centre-piece to their gardens.
I'm also hoping to exhibit this piece in the grounds of Dartington Hall in
June. The lithium glaze I'm intending to use gives a weathered limestone
effect and is only just melted at 05; I fire to a high 06/low 05.
What I'd like to know is how to protect such a soft non-glassy surface from
excessive algal growth without damaging the glaze. I shall be painting this
sculpture liberally with water sealant, and I know this is ok with this
glaze. I don't know if that will retard algal growth in itself? I know some
algal growth and moss and such can look most charming, and I don't intend
this sculpture to stay pristine and white, but this is the damp South West
of England, and I don't want her to look like a shaggy green monster within
the year! Would an application of any of the off-the-shelf preparations
garden centres sell do this glaze any harm? Has anyone had experience of
this? Many thanks,
Ama Menec, Totnes, Devon, UK.
