+ | Gegoten op glazen toplaag van 200cm x 60cm. Krimp bij drogen. | ||
+ | Droogtijd minstens 1 volle week, in de winter met hulp van electrische blazer. | ||
+ | Snelle schimmelvorming bij trage droging. | ||
+ | De extra toplaag was niet echt nodig, de plastic is nu redelijk dik. | ||
+ | De sterkte komt pas bij volledige droging, dus bij omdraaien zeer voorzichtig zijn! Of versterkende vezels gebruiken. | ||

+ | Add agar, water and glycerine into a pot. | ||
+ | Cook over medium heat and stir until the solution starts to boil and becomes viscous. | ||
+ | With a spoon remove any froth, so that the bioplastic will have a glossy, smooth surface. | ||

+ | snakeskin with agar, first try: | ||
+ | - agar agar: 3 gr | ||
+ | - glycerol: 4,5 gr | ||
+ | - water: 100 ml | ||
+ | => 100ml is not enough to cover complete snakeskin. Agar takes time to dry and is very fragile. | ||
+ | The pink (beetroot) snakeskin, made with gelatine instead of agar, is much stronger | ||
