Ar an gc\u00e9ad dul s\u00edos, d\u00e9anaimis labhairt faoina bhfuil i gceist i nd\u00e1ir\u00edre le cl\u00e1r sn\u00e1ith\u00edn ceirmeach.

Is iad na hair\u00edonna teirmeacha den scoth a fh\u00e1gann go bhfuil an t-\u00e1bhar seo chomh speisialta sin. Leagtar caighde\u00e1nach ag seasamh in aghaidh teasa sheasmhaigh suas go 1260\u00b0C (thart ar 2300\u00b0F), agus \u00e9ir\u00edonn leis na cinn n\u00edos l\u00e1idre ard-al\u00famanaim teocht suas go 1430\u00b0C n\u00f3 n\u00edos m\u00f3 a sheasamh. Is amhlaidh at\u00e1 s\u00e9 sin toisc go nglacann na sn\u00e1ith\u00edn\u00ed an t-aer isteach ar bhealach den scoth, rud a thugann seoltacht theirmeach f\u00edor-\u00edseal\u2014idir 0.08 agus 0.15 vata in aghaidh an mh\u00e9adair-Kelvin nuair a \u00e9ir\u00edonn c\u00farsa\u00ed te. Sa saol d\u00e1ir\u00edre, cialla\u00edonn s\u00e9 sin coigilteas m\u00f3r fuinnimh.

N\u00ed raibh aon teas ag sceitheadh amach a thuilleadh, rud a chialla\u00edonn bill\u00ed n\u00edos \u00edsle agus n\u00edos l\u00fa caitheamh ar an trealamh.<\/p>\n
Ach n\u00edl i gcruas teasa ach an t\u00fas. T\u00e1 na boird seo d\u00e9anta le maireacht\u00e1il i dtimpeallachta\u00ed garbh.

Anois, c\u00e1 bhfeictear na ruda\u00ed seo? I ngach \u00e1it i dtionscail ardteochta.
