What they have in common is the step, not the chemistry: a builder measures and combines components, pours the result into or over a form, and waits for it to set.\n\nThis page is a pointer. It carries no build instructions, quantities or costs — each material below has its own page where those live.\n| overview = {{TissueDB Material Class Table\n| rows = <tr>\n<td>[[TissueDB/Materials/Silicone, Castable|Silicone, Castable]]</td>\n<td>Two-part elastomer, platinum or tin cure</td>\n<td>The two parts are combined and poured into a mould.
