#MATERIAL TESTING ##Heat test 1: 50 - 110 degrees celcius I put them in the oven at the lowest setting of 50 centigrade for 10 mins, then for 45 mins. Then I turned the oven up to 70 degrees and again checked after 10 and 45 mins. | Sample | 50 C for 10 mins | 50 C for 45 mins | 70 C for 10 mins | 70 C for 45 mins | 90 C for 10 mins | 90 C for 45 mins | 110 C for 10 mins | | |-----|------------|---------|--------------|--------|---|---|---|---| | Alginate foil | - | - | more brittle | no change | no change | curls | turning yellow | more yellow, brittle, curled | Alginate composite | curls | no change | no change | no change | no change | no change | no change | no change | Agar foil | curls | - | slightly brittle | no change | no change | no change | no change | no change | Madder copper dye | - | - | - |no change | no change | no change | no change | no change | Kombucha paper | - | wax softened | no change |no change | very brittle, breaks upon touching | X | X | X | Biosilicone | melted | no change | no change | bubbles appear | no change | no change | no change | turns brown, bubbles have set | Biofoam | softens | wrinkles, slightly harder skin | softer inside, harder skin, wrinkles |no change | no change | no change | expands | shrinks and turns hard upon cooling | Bioresin | softens | no change | no change |no change | no change | gets brittle | softens | no change | Starch rubber | - | more brittle | softened|no change | dries, softens, edges get brittle | gets dry and brittle edges | no change | expands, turns darker, more brittle, cracks upon bending | Agar composite | - | - | - | - | - | - | - | - | | Mango leather | softens | no change | no change (beeswax slightly sticky) |no change | beeswax melts, very sticky | no change | stickier, softer | turned dark, brittle, breaks easily | Biolinoleum | softens | no change | no change |no change | no change | no change | softer | hardens again upon cooling, no change | Fish leather | - | curls up | no change | no change | shrinks, gets soft and flexible | no change| no change, stays flexible after cooling! | |Borax crystal| | | turns into opaque white | | |Alum crystal | | | turns into opaque white | | ##Water test 1: water resistant (spraying) I sprayed water onto the samples | Sample | with drying off | without drying off| |-----|------------|---------|--------------|--------| | Alginate foil | | | | Alginate composite | | | | Agar foil | | | | Madder copper dye | | | | Kombucha paper | | | | Biosilicone | | | | Biofoam | | | | Bioresin | | | | Starch rubber | | | | Agar composite | | | | Mango leather | | | | Biolinoleum | | | | **Other samples here!!!!** ||| ##Water test 2: submerged I submerged the samples in water at room temperature. | Sample | 30 mins | 1 hour | 2 hours | 4 hours |-----|------------|---------|--------------|--------| | Alginate foil | curls, turns thick and white | no change| no change | | Alginate composite | curls | no change| no change | | Agar foil | softens | no change | no change| | Madder copper dye | - | - |- | | Kombucha paper | softens | - | softens, color gets lighter | | Biosilicone | softens | soft and thicker | thickens | | Biofoam | softens, soaks up water a little| edges turn transparent |no change | | Bioresin | softens | soft and thicker| thickens | | Starch rubber | softens, like wet gouda cheese | no change | no change | | Agar composite | - | - | - | | Mango leather | softens and gets a little slimy | falls apart | X| X|X | Biolinoleum | softens a little| soft and flexible | thickens, softens | | Fish leather | expands, gets soft and somewhat flexible | | breaks when stretched | | Borax crystal| - | - | - | | Alum crystal | | starts to dissolve | | completely dissoved | Alginate string | - | absorbs water, becomes flexible | more flexible |
